THE CANADIAN ENTOMOLOGIST. 



nothing positive to distinguish it from the other group represented by 

 Gangarides and Cnethocampa. 



The larva of torrefada certainly possesses a fine development of 

 secondary hairs ; but so does Datana and, to a less degree, Malalopha. 

 Unfortunately, the secondary coating is so well developed that the vi^arts, 

 even if present, are obscured, and I cannot make out their arrangement 

 on the thorax. On the abdomen, the pale spots representing the wart 

 areas rather suggest the retaining of wart iv. at the expense of v. ; but 

 the character is so faint that nothing definite can be argued from it. 



Thus we see that nothing at present contradicts the position assigned 

 to Apatelodes by Mr. Schaus; though, on the other hand, nothing positive 

 confirms it. Shall we add the family Eupterotid?e to our lists on this 

 evidence ? 



I would like to remark that if it should turn out, as I now suspect, 

 that the Lasiocampidae belong to the Lymantriid section of the Noctuina, 

 and that Mr. Schaus is right in assigning Apatelodes to the Eupterotid^e, 

 then the close resemblance of A. angelica larva to a lasiocampid, to 

 which I have referred [See Ann. N. Y. Acad. Sci., Vol. VIII., p. 229], 

 may be better understood. 



A FEW POINTS IN COLLECTING ICHNEUMONID^. 



BY G. C. DAVIS, AGRICULTURAL COLLEGE, MICH. 



The Ichneumonidte have habits and peculiarities as distinctly their 

 own as other families and orders of insects. In collecting them one 

 will find, after a little experience, that certain species or even groups will 

 frequent certain places where conditions are favourable and their host is 

 likely to be found. 



The Phnplmce, with long ovipositors, should be sought for in a 

 wooded region around dead or diseased wood, where their hosts, the 

 borers, are at work. One of the best places I have found for collecting 

 them is around piles of dead block-wood cut the preceding winter. 

 They are most common in Michigan in June and early July. 

 Xylonomtis and Grotia may often be found as pups in the hollow stems 

 of shrubs in the spring, where they have already destroyed their host and 

 are securely wrapped in a papery case of their own. The portion of the 

 subfamily with shorter ovipositors, such as Pinipla and Glypta, apparently 

 work on caterpillars, and are quite as common during the fall as in the 

 summer. The Ophionince are much the most common in the fall. The
