The following brief account of the formation and growth of the Lyman Entomological Museum, and of some of the main figures associated with it, is not intended to be complete in detail. For those readers who wish further information a list of references is included. These are not referred to in the text.

Entomology began in this country, and indeed in most countries, as a direct result of the efforts and interest of amateur naturalists. The Lyman Entomological Museum began in this way. Henry Herbert Lyman was a pioneer entomologist of Canada, and although his busines commitments were extensive, he still made time to follow his primary interest, studying and collecting Lepidoptera.

Seventy-one species of Tabanidae from Quebec are listed.

Ramakrishnaia is a south Indian genus of Pyrgomorphidae related to Colemania. A lectotype for the type species of the latter, C. sphenarioides, is here designated. Two species of Ramakrishnaia have hitherto been described: the type species, R. notabilis (for which a lectotype is here designated), and R. raoi. R. gracilis, a new species from Coorg, is described. R. raoi, on the basis of its phallic structures and external morphology, is removed to a new genus, Nilgiracris.

The Pyrgomorphidae represent a distinctive family of acridoid Orthoptera comprising 127 genera and over 400 species. The systematic history of the group is outlined and its name is discussed. On the basis of external morphology and phallic structures it has been found possible to divide the family into tribes. Most of these have been recognized previously, but several new ones have been erected to accommodate anomalous genera or parts of former tribes that have proved to be heterogeneous. The genera fall into no fewer than 29 tribes and 8 subtribes, which reflect the antiquity of the group; phylogenetic relationships remain rather obscure. An extensive key to the tribes and subtribes (incorporating both external and phallic characters) is given and the genera belonging to each are listed. Diagnoses of three new genera and a new subgenus are appended. Geographical distribution is discussed. The great majority of Pyrgomorphidae are found in the Old World tropics and subtropics, but some are American and a few reach temperate latitudes both north and south. A very high degree of endemism amongst genera is shown by all regions in which the group occurs, except the Palaearctic. The African and Malagasy faunas are the richest, but the group probably originated further east. Madagascar, Australia, the Papuan subregion and C. and S. America all have their own very distinctive tribes and genera. No genera are common to Old and New Worlds. The latter was probably invaded from Asia at least twice. Pyrgomorphidae appear to be comparatively recently incursive into the Palaearctic region. A new Palaearctic fossil genus is proposed.

The specific name curtipennis (Harris) is reinstated for North American Chorthippus, which is not (as erroneously supposed) conspecific with an Old World species. A neotype is designated and described for C. curtipennis (Harris), and a lectotype is chosen for C. montanus (Charpentier).

The status and the condition of the type specimens of Orthoptera described by the Abbé Léon Provancher, the pioneer entomologist of Québec, are discussed.

Records of captures of Schistocerca in Canada are listed from sources in literature and from specimens in collections. Synonymy of the species in question is given. S. americana occurs rarely in southern Ontario and S. emarginata in the southern Prairies.

The genus Gryllita Hebard is redefined on the basis of the internal genitalia and external morphology. Three additional species from Haiti are described: G. bondi, G. arndti and G. uhleri. A description is given of the external morphology of Hispanogryllodes rehni.

On the basis of the relative size of the spermatophore sac the subfamily Gryllinae is separated into two tribes, Gymnogryllini and Gryllini, this structure being small in the former and very large in the latter. Each tribe is further divided into two subtribes on the basis of consistent differences in the shape of the epiphallus. Six new genera are added.

The presence of styli on the epiphallus of species of Turanogryllus Tarbinski is suggested as evidence for the origin of the male genitalia from the segmental appendages. Possible homologies of the structures of the male genitalia of Grylloidea and Acridoidea are suggested.

A new species of the genus Arachnoscelis Karny (Orthoptera: Conocephalidae), A. rehni, from Costa Rica is described and compared with A. magnifica Hebard from Panama.
