Coleopierological Notices, III. 13 



Elyti-a with series of large rounded shallow punctures, the intervals each with 



a single series of small coarsely setigerous punctures striatlis 



Elytra without series of large shallow punctures, the punctuation however 

 having a more or less distinct serial arrangement. 

 Apical angles of the prothorax rounded. 



Prothorax longer than wide, not or extremely feebly and narrowly im- 

 pressed ; body ferruginous opRCtllUS 



Prothorax quadrate. 



Ferruginous ; pronotum broadly, rather strongly impressed. 



cavicollis 

 Black ; i^ronotum more shining, more sparsely jiunctate, less convex 



and less impressed along the middle planicollis 



Prothorax much wider than long, nearly as wide as the elytra ; l>ody 



black ltai*TlllllS 



Apical angles of the prothorax not rounded. 



Larger species; eyes large; elytral series well marked cai'Oliiiae 



Small species ; eyes small ; elytral series more feebly defined. 



californiciis 

 Elytra with the punctures denser, confusedly arranged or without distinct 

 serial arrangement; apical angles of the protliorax not rounded. 

 Prothorax as long as wide or extremely nearly so ; anterior coxae widely 

 separated. 

 Anterior tibiae gradually much broader from base to apex, not everted 

 externally ; basal angles of the prothorax narrowly rounded. 



ciirtiilits 

 Anterior tibiae slender, gradually but slightly broader, and finely, exter- 

 nally everted at apex ; basal angles of the j^rothorax not rounded. 



parallelopipediis 

 Prothorax much wider than long pilllCtattls 



In the genus Lyctiis the slight serricorn affinity indicated perhaps 

 through some extinct or undiscovered genus allied to Psoa, is par- 

 allel to the melyride affinity of Berginus, as shown by its general 

 habitus, and means nothing more, the two affinities being about 

 equally pronounced. 



Li. caroliliaB n. sp. — Parallel, moderately slender, rather convex, ferru- 

 ginous, the head and prothorax darker than the elytra ; integuments shining, 

 the vestiture rather inconspicuous, yellowish. Head rather coarsely, moder- 

 ately densely punctate ; antennae slender, one-half longer than the head, the 

 club moderate, joints three to five subequal, nearly twice as long as wide. 

 Prothorax about as long as wide, the apex distinctly wider than the base, 

 evenly, strongly arcuate throughout ; base broadly but less strongly arcuate ; 

 sides feebly convergent from the apical to the basal angles and just visibly 

 sinuate throughout ; apical angles feebly, laterally prominent, right, very 

 slightly blunt but not rounded; basal angles slightly obtuse but not at all
