at all impressed, not very coarsely, ratlier feebly, evenly, sparsely punctate, 

 the basal fovese broadly impressed, distinct. Elytra a little more than three 

 times as long as the prothorax and scarcely at all wider, gradually, acutely 

 ogival in apical two-fifths ; sides parallel, nearly straight ; disk very coarsely, 

 deeply striate, the strial punctures unusually coarse and deep toward base 

 but totally obsolete toward apex, the intervals rather convex, finely, sparsely, 

 confusedly punctate. Abdomen finely but strongly, sparsely punctate. Legs 

 slender ; basal joint of the hind tarsi equal in length to the remainder. 



31ale. — Not examined. 



Female. — Eyes separated by their own width ; third and fourth antennal 

 joints equal ; tarsal characters similar to those of punctulata. 



Length 7.5 mm. ; width 2.7-2.9 mm. J . 



Connecticut; Pennsylvania. 



The present species is chiefly notable for its extreme northern 

 habitat. The eyes are much smaller than in any of the others here 

 enumerated, and it is also remarkable in having the punctures of 

 the elytral strias unusually coarse and conspicuous toward base; 

 but, as is often the case, they become completely obsolete toward 

 apex. 



HYMENORUS Muls. 



The two genera Lobopoda and Ilymenorus are peculiarly Ameri- 

 can, and together comprise probably more than one-half of the 

 entire family in our continent, the former being essentially tropical 

 but entering the southern parts of the United States in moderate 

 number, and the latter northern in its distribution but overrun- 

 ning Mexico with many species. Hymenorus is a nearctic, and, to 

 some extent also, a palsearctic genus, while Lobopoda is entirely 

 neotropical. Hymenorus is one of the best defined of our genera, 

 although the species are comparatively diversified in facies. The 

 species are as a rule much smaller than those of Lobopoda. 



The lobes of the tarsi in Hymenorus generally differ from those 

 of Lobopoda in being small, and never more than two in number 

 on the two anterior and one on the posterior pair. The last joint 

 of the maxillary palpi is usually in the form of a right angled tri- 

 angle, with the apex and the outer side subequal in length, but rarely 

 it becomes more dilated and quite similar to the prevailing type in 

 Lobopoda and Allecula. The anterior coxse are always separated 

 by a narrow but distinct prosternal process, and the posterior by a 

 narrow acutely angulate abdominal projection, the entire structure
