130 THE CANADIAN ENTOMOLOGIST 



Do the cool and warm conditions during the flying season work their opposing 

 effects on the adult or the larva, or both? The female Halicti pass the winter as 

 adults, but live on until summer when they raise their brood. They have short 

 coats and are of small size. The honey-bee raises its brood and passes the night 

 in activity under the conditions of all seasons in an artificial heat provided by 

 the colony. The European species of Andrefia, A. gwynana Kirb. has two broods 

 in the season. The spring-flying adults raised the previous summer hibernate 

 as adults and are more robust with longer coats than the summer flying adults 

 which are raised in the spring and have the slender, feeble appearance of the few 

 species of Andrena found in the tropics. 



Queens of the Italian bee that have been chilled in the pupa stage have the 

 orange part of the integument darkened, and queens of Bomhiis lapidarius L. that 

 slowly passed the pupa stage in the lowest temperature that could support life, 

 had their black and red coat changed to brown. 



How far the fact that British forms have a larger number of close allies 

 on the Pacific Coast than in Eastern Canada is due to migration via Asia and how 

 far to the action of similarity of climate cannot be estimated until our 

 knowledge of Siberian forms, at present meagre, is greatly increased. The 

 hairs clothing the body are of value to the bees for gathering pollen for which 

 they are admirably adapted, being branched but unbranched in wasps. Their 

 value for keeping the insect warm in chilly weather is apparently of secondary 

 importance because wasps are almost as scantily clad in the north as in the 

 south, and the parasitic bees are scantily clad. Bright colours and striking 

 patterns, whether of coat or tegument, for instance in Bomhus and many parasitic 

 bees and many wasp genera, are usually of the warning kind and therefore are 

 liable to regional convergence. In England, most of the species of Bomhus 

 have a white or a red tail. In Canada the only white or red-tailed species 

 are in the western mountains and the north. 



CATOCALA ULALUME, A CORRECTION. 



BY G. H. FRENCH, CARBONDALE, ILLINOIS. 



It may be unfortunate that Mr. Herman Strecker did not figure all of the 

 new species that he described, for his descriptions, like those of some of the 

 rest of us, were not always clearly drawn. Another unfortunate thing, for me, 

 is that during a few years in which I was compelled to drop entomological work 

 some of my material was lost, among which was C. ulaliime. The specimens 

 upon which were based my note in the Canadian Entomologist of January, 

 1919, page 16, were Dr. Holland's C. Carolina, and that is really a variety of 

 C. flehilis. This species is too small for C. nlalume. 



Since writing the above-mentioned note I have seen material from several 

 localities outside of Southern Illinois, containing a number of forms of C. lacry- 

 mosa and C. dejecta. One of these, I think from Kentucky, has the bluish sheen 

 of C. dejecta, with no noticeable brown except a narrow subterminal shade of 

 very dark brown, not noticeable except under the lens. This specimen had 

 t. p. dentation of C. lacrymosa, but lacks the white along the t. a. and t. p. lines 

 near the posterior margin of the wing that is so prominent in C. lacrymosa. 

 The whole wing is pretty evenly dusted with black atoms.
