LISPINUS Er. 



L. aequipunctatus, niger nitidus, supra fere aequalifcer punctatus, fronte bi- 

 foveata, thorace basi utrinque lougitudiualiter impresso, qnadrato, latitudine 

 vix longiore, lateribus parum rotundatis ; antennis piceis, pedibus obscure fer- 

 rugiiieis, abdominis segmentis ventralibus postice tesfcaeeo-marginatis. Long. 

 4-5 mm. 



Under pine bark at Canada de los Diefjos, New Mexico. The punc- 

 tures of the head are a little smaller than those of the thorax and ely- 

 tra, but those of the dorsal surface of the abdomen are quite as strons^ 

 as those of the thorax, though not as rugose as those of the elytra. 



This species differs from all previously described by the strongly 

 jnarked punctures of the dorsal abdominal segments. 



OLIBRTIS Er. 

 0. nigricollis, ovalis, convexus, capite tboraceque nigris, boe longitudiiie du- 

 ple latioro, antrorsum magis angustato, basi medio subtiliter marginato, ely- 

 tris laete rufo-flavis, striis internis duabus distiuctis; subtus piceo-testaceuo 

 pedibus testaceis, antennis flavis. Long 3 mra. 



One specimen. New Mexico. Of the size of 0. bicolar, but some- 

 what broader and more regularly oval: the rows of punctures of the 

 elytra are very fine, and scarcely visible. This species belong.'? to the 

 same division of the genus as 0. bicolor. having the metastermum con- 

 nate with the mesosternum, and protuberant between the middle coxie.* 



OCHODAEUS Lep. 



In the vicinity of Caiion Blanco, New Mexico, I collected six spe- 

 cimens of this genus, which flew into m}' tent attracted by the light 

 of the lantern. They difter greatly in size, and in the sculpture of the 

 head and elytra, and in comparison with other specimens before me 

 from the collections of Mr. Ulke and myself, indicate that the species 

 of North America are more numerous than has been heretofore suspec- 

 ted. Much larger series of specimens must be obtained before the .study 

 of the genus can be regarded as even moderately perfect. 



The six specimens represent four distinct forms, none of which are 

 precisely like the three species previously in my collection. J have 

 endeavored to define the most prominent difi'erences between tliem, and 

 two additional ones now before mc, in the following table : 



* I avail myself of the present opportunity to describe a beautiful species of 

 OUbru.i, found by Mr. Ulke in the interior of the state of New York. 



O. VITTATUS. liitiiH ovalis, convexus, supra nisro-piceus nltiduB, marsinibua rufo-piccis, thorace longitu- 

 dine duplo latiore, antrorsum inagid angustato, biiai meilio subti'iter marginato ; elytrir? margine vittaque 

 utrinque doraali lata rufu-tcatacea, striie internlB duabus distinctis; subtus tcstacous, autL-nui;> pcdibusqu** 

 fere flavis. Long. -2 mm. 



Belongs also to the same division as 0. bicolor, but is more broadly oval, hav- 

 ing nearly the outline of Phalacrufs politus. The outlines of the two broad ely- 

 tral vittae- are not very well defined, and they almost meet at tlie ijutiire n>-ar 

 the tip.
