there is much doubt. The elvtron is prettv well an-hed, equal nearly to 

 the tip, thru rapidlv rounded nil', indicating an ovate beetle with the shape 

 uf a IIv<lri>liius <>r a shorter insect, and of about the si/'- of Helophoruslineatus 

 Say. Ki-ht faintly impressed uniinpunctured stride are visible, the outer 

 one, ami to some extent the one next it, deeper ; these two unite close to the 

 tip, curving strongly apically ; the next two curve slightly near their 

 tivmity, but an- much shorter, not reaching the fourth stria from the suture. 

 which, like the remaining three, pursues a straight course to the seventh 

 stria. The surface between the stria; is nearly smooth, piceous. 



Length of fragment, 2.4 mm ; breadth of elytron, 1.35 mni ; distance apart 

 of the stria-. 0.15

A single specimen exhibits the dorsal surface, but with part of the th 

 gone. It represents a species a very little larger than II. fuscipes < 'urt of 

 California, and is apparently allied to it, though slenderer; the head and 

 eyes an- as in that species; the thorax shorter and the elytra longer and 

 more tapering at the tips, the extremities of which, however, are not pre- 

 served ; they are furnished with ei^ht d.-licate stria?, in which the punctures 

 are scarcely perceptible even when ii u Lfu i tied : the surface, otherwise ap- 

 pears to In- smooth, but is not well preserved. The scutelhim is as in the 

 recent .-.pecie* mentioned.
