THE CANADIAN ENTOMOLOGIST. 297 



puncture supports a hair, and, curiously enougli, the finer the punctures, 

 the longer are the hairs, so that the Pacific coast females, with comparative 

 sparse punctuation, are not conspicuously liairy. European examples are 

 before me which are in no way distinguishable from those taken on the 

 Pacific coast. To what extent individuals vary in Europe is unknown, 

 but, regardless of sex or locality, there is much variation here. The 

 following observations are made from a study of about 30 examples from 

 Canada, Custer and Conejos counties, Colo.; Las Vegas Hot Springs, 

 New Mexico, and various places on the Pacific coast, namely : The eyes 

 are not uniform in size, depth of emarginalion, nor distance apart either 

 above or below ; the same joints of the antennae are not always of the 

 same length, and their united length is much greater in some individuals 

 than in others ; the antennae differ also in the degrees of compression, 

 coarseness, fineness and density of punctuation, while in some examples 

 the outer joints seem glabrous ; in others there is an evident microscopic 

 pubescence ; the thorax is variable in every way, and in few examples is 

 there more than an approximation in every respect ; the degree of angula- 

 tion of the sides of the thorax varies from very strongly defined to 

 scarcely any, and in some examples the angular point is before the middle 

 in others behind it, while in the majority it is about the middle of the 

 margin ; the thoracic spine at the angle may be small or large, obliquely 

 vertical, or sometimes directed anteriorly or posteriorly ; the margin of the 

 thorax behind the spine is narrowed in some individuals by a straight line, 

 till it meets the margin of the base in nearly a right angle ; in others it is 

 either sinuate or arcuately rounded, forming no angle at its conjunction 

 with the base ; the surface may be nearly equal with a dorsal channel, 

 more or less deep, but usually it has many irregular inequalities ; thf' 

 punctuation varies from the exceedingly dense (almost granulate) r.ud 

 rather fine, to that which is sparser and coarser, with the punctures well 

 separated. The scutellum is also variable, sometimes large and equi- 

 laterally triangular, and again transverse and rounded at apex. There are 

 no well defined races. The species is widely distributed through eastern 

 and western Siberia, the countries along the Amur, and the mountainous 

 parts of Central Europe. 



Another species of Tragosoina, in some American collections for 

 many years, has lately been described by Mr. T. L. Casey, from the male, 

 under the name spiculum ; of this I have not seen the female, which is 

 probably Mr. C^sty's pilosicornis, in which case, if the locality is correct,
