The description of the larva of Plaiythyris by Clemens reveals un- 

 expected resemblances to Thyris, both in form, quality and habit. When 

 the immature stages present so many points of agreement it is incorrect 

 to say that the genus contradicts nearly every family character. The 

 points wherein the moth contradicts Thyris have been comparatively- 

 given by us. We lay stress upon the thoracic and antennal characters as 

 being very different from Thyris — so much so that we consider it to be- 

 long to a distinct tribe. Mr. Smith uses the characters we give. He 

 emphasizes the fact that we do not describe the venation. Of our type 

 we could not well denude the wings, but Dr. Clemens describes the 

 venation fully (]. c. p. 349 seq.) and it would seem that putting what 

 Dr. Clemens says and what we say, originally and subsequently, a pretty 

 full statement could be compiled as to the structure oi Plaiythyris. Joined 

 to this we figure the moth, from both sides, and Boisduval, as Say, very 

 probably figures a second species oS. Plathythyris as a Thyris, Subsequent 

 descriptions of North American Platythyrince are also extant; the species 

 except ocidatuna (^fasciaid) are unknown to me in nature. 



Collecting Notes. 



By Chas. Liebeck. 

 I have noticed, while looking over my last volume of Ento, Am. 

 lately, an article by Mr. A. M. Weeks entitled "Capturing Carabus ser- 

 ratus. " In this locality as well as in the neighborhood of New York 

 City, it is infrequently met with, an occasional specimen during hibernat- 

 ing season, and must be collected methodically. The idea of collectmg 

 them by sugaring is a very good one, but we have never tried it. Our 

 method of collecting them will be explained by the following account of 

 one of our trips. On the loth of April Mr. Wenzel and myself made a 

 trip to Franklinville, situated on the outskirts of the upper end of Phila- 

 delphia, on the banks of the Wingohocking Creek. At the point of our 

 operations the creek runs between two lines of hills with moderately slop- 

 ing sides. Here we commenced our search by scraping among the loose 

 earth, dead leaves, and general debris left over from the fall season. From 

 about half way up, to the top of the hills, after a diligent search, w-e 

 found about 16 specimens of CVc^r«5 5/^«05/o»/«5 and a number of species 

 o{ Pterostichus. While near the waters edge at the foot we found about 

 25 specimens of Crt/'a<^«5 5^r;'a/z/5, a like number oi limbatus and the 

 common tmictus. C. sylvosus, the only other species of Carabus found 

 in this vicinity, has also been taken here in the same way, but not on this 

 occasion. We also found besides the above species Olisthopus parmatiis, 

 Atranus pubesceiis, Platyiius octopimctatus, Diccelus ovalis, and numbers 

 of species of the commoner Carabidse.
