194 ENTOMOLOGICAL NEWS. [October, 



The genus Cephaloon has for its type lepturides Newm.. which 

 is distinguishable at once from any other species of the family by 

 its short clavate antennae. It inhabits the lake regions of North 

 America. 



The species of Sponidium are somewhat numerous, and are 

 exclusively western, inhabiting the true Pacific coast faunal prov-, 

 ince. Those before me may be separated by the following char- 

 acters from the female throughout : 



Eyes separated on the front by about their own width; antenna;- much 

 longer than the head and prothorax together, the eighth joint but 

 little longer than the ninth. Washington (State) . tenuicorne Lee. 

 Eyes separated on the front by very much less than their own width;, an- 

 tennae but little longer than the head and prothorax, with the 

 eighth joint generally much longer than the ninth. 

 Head shorter, the basal part, including the eyes, distinctly wider than 

 long, the distance, from a vertical viewpoint, from the posterior 

 limit of the eyes to the neck but little greater than the distance 

 from the same point to the inner limit of the eye; prothorax but 

 little longer than wide, broadly impressed along the middle ante- 

 tenorly. British Columbia (Caraboo District) . . piceum Horn. 

 Head more elongate, the basal part as long as wide, qr very nearly; 

 distance from the posterior limit of the eyes to the neck much 

 greater than to the inner limit of the eye; prothorax distinctly 

 longer than wide, generally unimpressed. 



Neck broader, as wide as the interantennal distance, the nuchal con- 

 striction nearly straight across the dorsal surface. Idaho. 



ornatum Csy. 



Neck more slender, distinctly narrower than the interantennal dis- 

 tance, the nuchal constriction strongly arcuate. 

 Tempora straight; distance from the epistomal suture to the eyes 

 almost as great as the length of the epistoma; body testaceous, 

 the elytra black throughout. Coast regions of middle California. 



bicolor Horn. 



Tempora broadly and just visibly sinuate; distance from the epis- 

 tomal suture to the eyes much less than the length of the epis- 

 toma; elytra generally pale, with the suture narrowly blackish. 



Rocky Mountains versicolor Csy. 



A specimen of versicolor, sent recently by Mr. Fuchs, is labeled 

 ' British Columbia (Caraboo District)." The species may pos- 

 sibly extend along the Rocky Mountains as far to the southward 

 as Colorado. 



Cephaloon ungulare, of LeConte, is the type and only species 

 of Typitium; it is of unusually slender form and occurs in the 

 northern Atlantic regions of North America.
