A Note on Chanopterus, Boh. 

 By Geoege H. Horn, M. D. 



This genus was founded by Bobeman (Eugenies Resa Ins. p. 98) 

 on the heteromerous coleopter collected at the Straits of Magellan. It is 

 about .3 inch long, brown or piceo-teslaccous in color, shining. Mv 

 attention was called to it, more especially, by its resemblance in form to 

 ^gialitcs, although larger and differently colored. Through the kind- 

 ness of Mr. Chas. O. Waterhouse a specimen was given me from the 

 collection of his father, in which it boic the wwxnsd Chitoniscus hrevipcnnis, 

 probably unpublished. 



In studying the species more closely, it was found that Chanopterus 

 had comparatively little in common with /Egialites. The anterior coxal 

 cavities are widely open behind, removing it from any relationship with 

 the TenebriomdcB. The head being rather broad behind the eyes and the 

 thorax without distinct lateral margin the affinities are decidedly in the 

 direction of the i\Ichiiidrvi(Lc and PythicLe, to the latter more especially. 



At this time it is not necessary to discuss the propriety of retaining 

 the two cited families as distinct but I have already expressed the opinion 

 that there is not that fundamental difference in structure which should 

 separate families. 



Chanopf ems paradoxus was placed by Boheman in the Tenebrionide 

 tribe Helopini. As the insect was unknown in nature to Lacordaire he 

 merely mentions it in the supplement to the fifth volume and the Munich 

 Catalogue adds no further opinion. 



From the study at present given, it seems an undoubted Pythide, as 

 the family now stands, and while not closely related to either of the tribes 

 proposed by Lacordaire it seems most nearly allied to Lalpingus although 

 forming a tribe apart. 



Mr. J. B. Smith's Monograph of the Sphingidce is in press and will 

 be ready for publication at no remote date. It will be published by the 

 Am. Ent. Soc. It will be the most exhaustive and valuable work on die 

 subject.

Mr. Hy. Edwards is hard at work on a bibliography of the adolescent 

 stages of Lepidoptera, and as we are informed expects to complete the 

 same some time during the Summer.
