238 THE CANADIAN ENTOMOLOGIST. 



some process. I find it very satisfactory to collect them alive and to place 

 them on the slide of the microscope in a drop of chloroform, which quiets 

 them for a minute, and when reviving the antennae and legs are extended 

 slowly and may be seen rather better than by dissection. 



Raised from the same wood with the above was a specimen of Hadi'o- 

 bregmus .18 inch long with eleven jointed antennae, which \i not pumilus 

 is a new species, the size constituting the principal difference observed. 



Several examples of Xyletinus peltatus were likewise bred from this 

 wood. 



Purpuricenus axillaris Hald. (Tr. Am. Phil. Soc, X., 31). — This fine 

 species is not uncommon here, and this season numerous examples were 

 bred from hickory wood deadened two years and one-half ago. In the 

 catalogue it is set down as a variety of humeralis Fab., but the reason is 

 not very obvious. It is smaller, .45 to .65 inch, (Haldeman gives, .50 to 

 .75 inch, but in over 100 examples I never saw one over .65 inch, .50 to .55 

 inch being the usual length) ; cylindrical in outline ; thorax moderately 

 foveate-reticulate ; elytra sparsely moderately punctured on the basal 

 third, which is mostly of a pale lemon color to orange yellow ; the apical 

 two-thirds is entirely black, the anterior portion of which is punctured a 

 little more finely than the yellow portion, and the posterior very finely 

 and densely ; a black hair arises from each puncture forming a dense pile 

 that completely conceals the punctuation \ the underside is moderately 

 finely sparsely punctured ; the black and the yellow portions of the 

 elytra are separated transversely by an irregular border, though the 

 black has no tendency to advance along the suture, but rather the 

 reverse. 



Hiiineralis is larger, .70 to i.oc inch, considerably depressed and 

 broader in proportion to the lengths ; the thorax is very rugosely foveate- 

 reticulate ; the elytra on basal third are coarsely sparsely deeply punc- 

 tured ; the punctures on the apical black part are somewhat finer but not 

 dense, and are not concealed by the black hairs ; the underside is coarsely 

 punctured ; the apical black of the elytra advances normally along the 

 suture to the scutellum, leaving a triangular basal space on each side 

 extending to the marginal third of a bright scarlet color, but sometimes 

 orange. In some individuals the basal spot becomes dilated posteriorly 

 so as to be separated only by a black sutural line, and then the specimen
