The genus Elsiamis is a member of the subfamily Helmin^e 

 (Elminas) separated by Dr. Sharp from the genus Elmis and its near- 

 est alhes by the mesosternal groove being hmited anteriorly by two 

 distinct raised lines and the longer maxillary palpi. 



Helmis ornatus, new species. 



Oval, black, underside and legs pale ; elytra with large transverse humeral 

 and ante-apical pale spot. 



Prothorax broad, gradually arcuately narrowing to apex ; apical and basal 

 angles acute ; disk on each side with two longitudinal carinae of which the 

 outer one is short and the inner one long, reaching from base to very near the 

 apical margin, surface finely punctate. Elytra at base scarcely wider than the 

 thorax at base, sides arcuate ; strial punctures distinctly impressed ; intervals 

 feebly convex and finely punctate ; surface feebly pubescent. Length 2 mm. 



Montana. 



From our similarly marked oval species this new species will be 

 readily known by the entire inner thoracic stria or carina and from 

 those possessing an entire stria by its oval form anrl ornate elytra. 



Family Lampyrid.ii.

 1823. 



The figure of Lycostouuis liticicollis Chev. in Biologia Cent. Am. 

 Col., Vol. III. pt. 2, pi. I, fig. 4, and the description agree very closely 

 with Say's species and I have very little doubt that the two are the 

 same. 



Gorham. in treating the Central American species in the Biologia, 

 does not mention the genus Rhyncheros, which is, in my opinion, not 

 well founded, as most of the species of Lycostomus in our list have 

 a more or less short beak. 



Lycostomus femoratus, new species. 



Resembles in coloration and form fnlvellus Lee. but differs in having less 

 arcuate hind tibiae, femora in great part yellow and only near apex black ; 

 median thoracic spot much smaller, the thorax wider and more distinctly' tri- 

 sinuate in front, alternate elytral costse distinctly more elevated than the 

 others especially in apical half. Length 14 mm. 



Huachuca Mts., Arizona. 



This is the species I reported in my list of Lampyridoe from the 

 Huachuca Mts., Arizona^ as fulvellus but having seen lately Colo-
