My first work with the comrnon mantid, Stagmomantis carolina John began accidentally. One afternoon in early May, at Dallas, Texas, a number of egg masses of the mantid were placed on my desk for inspection. In looking them over I noticed that several had been parasitized and that in others the nymphs had already emerged. I paid very little attention to the unhatched eggs. The next morning May 7, 1927, my desk was covered with numbers of ungainly little brownish green creatures that raced madly about and made frantic efforts to hide behind books and papers. Thirty of these mantid nymphs were captured and placed under a glass lantern globe. A week later a second egg mass hatched. These two broods, together with a stray nymph I found, furnished me with material for observations throughout the summer.

Through the courtesy of Dr. J. McDunnough I was recently privileged to examine the collection of Anthidiine bees in the Entomological Branch of the Canadian Department of Agriculture, including both identified and unidentified nraterial. The list of species determined or confirmed follows, with comments.

B1ack, antennae partly ancl the palpi apically, reddish; face and cheeks yellow. Superficially very sinrilar to daemon Wiedmann from Brazil but at once distinguished by the short, fine yellow hair on the parafacials and cheeks and the shape of the male genital forceps, which are ridged as in apicilera Walker. Length, 11.5 to 13 mm.

The following species are described as new:

Arctocorixa compressoidea sp. n.

Size: 5.4 mm. long.

Color: Dark. Seven light bands of pronotum narrower than the dark ones and caudal ones deeply impressed; third and fourth bands often united on ends ; longitudinal median pale line on pronotum. Pale transverse bands of clavus oblique and entire on basal half ; apical ones slender, broken, crooked and few in number. Pale lines of corium also slender, broken, sometimes mere transverse dashes arranged in longitudinal series. Membrane smoky brown, pattern almost obliterated. Elytral suture, line between corium and membrane and embollium reddish yellow. Vertex in all my specimens more or less darkened. Limbs and venter pale.
