322 Coleopterological Notices. 



elytra have each five fine ridges, the intervals being finely, sparsely 

 and sublinearly punctate. The epipleurse are extremely narrow and 

 do not occupy the entire inflexed sides except at the humeri where 

 they become rapidly dilated as in many Tenebrionides. The meta- 

 sternnm is extremely long, the side-pieces rather wide anteriorly, 

 but rapidly narrowing thence to the apex, where they are generally 

 more or less covered by the elytra. The lateral margins of the 

 prothorax are marked by an extremely feeble fold which is generally 

 completely obsolete near the apex. In the presence of a fine longi- 

 tudinal line near the sides of the pronotura Narthecius exhibits a 

 line of consanguinity with the true Cucujinas, and the synthetic 

 nature of the genus is proved in addition by several other structural 

 characters. 



The sexual modifications of the Passandrinse are not very con- 

 spicuous and are generally extremely feeble, in marked contrast to 

 the Cucujinaj where these differences become extreme. I have but 

 little doubt therefore, that the characters which are employed in the 

 following table will be found practically independent of sex. The 

 three species before me may be thus distinguished : — 



Median apical process of epistoma broader, bifid at apex. 



Head very long ; occiput with a distinct broadly impressed median groove 

 toward base ; antennse scarcely as long as the head ; nuchal constric- 

 tion distant from the eye by ner.rly twice the length of the latter; 

 supra-orbital carinse extending behind the eye a distance far exceeding 

 its length. Prothorax much shorter than the head : pronotum un- 

 evenly punctate, more coarsely near the middle, finely so elsewliere. 

 Elytra shorter than the head and prothorax together. Length 2.8 mm.

Head scarcely longer tlian wide ; occiput without median groove ; nuchal 

 constriction distant from the eye by scarcely more than tlie length of 

 tlie latter ; supra-orbital ridge arcuate, obsolete at less than the length 

 of the eye behind its posterior margin ; antennse nearly one-half longer 

 than tlie head, the basal joint mucli longer than wide, convex, last 

 joint oval, longer than wide, much narrower than tlie tenth. Protliorax 

 longer than tlie head, longer than wide, nearly as in grandiceps, but 

 evenly and very densely punctate througliout. Elytra distinctly longer 

 than the head and prothorax together. Length 2.6 mm. California

 present time, which are in conflict with the language or delineations of the 

 revision referred to, must be considered as abrogating the latter.
