414 Coleopterological Notices, V. 



Elytral punctures distinct and mucli less sparse. 

 Abdomen black. 



Elytra piceo-fuscons pilosellum 



Elytra flavate, with a triangular scutellar spot of blackish. 



sciitatum 

 Elytra clear and uniform pale flavate throughout. 



piibcruliim 



Abdomen flavate, more or less clouded with piceous toward the middle 



and apex ; elytral punctures very strong flavescens 



Species of the Atlantic region. Polished ; prothorax transverse, subimpunc- 

 tate ; elytra piceous in the male, with paler side margins, frequently 

 wholly flavate in the female, the punctures sparse, feeble and ill-defined. 



laevicolle 

 Punctures of the elytra exceedingly dense. 



Elytra normal, large, one-half or more longer than the prothorax. 



Dark in color, the sides of the elytra sometimes feebly and indefinitely 

 paler and the lateral and basal edges of the pronotum testaceous. 

 Ocelli small, clearly defined, more prominent and less distant. 



Prothorax in the female less transverse, two-fifths wider than long, 

 more strongly narrowed toward apex, the sides more narrowly flat 

 and explanate near the basal angles ; elytra in that sex one-half 



longer than the prothorax Opacillum 



Prothorax in the female nearly three-fifths wider than long, less 

 narrowed toward apex and with the sides of the disk near the 

 basal angles more broadly concave and reflexed ; elytra in that sex 

 nearly three-fourths longer than the prothorax (veterator Csy. 9 )• 



modes til in 

 Ocelli large, sufl'used and distinctly more distant ; pronotum more 

 strongly punctate ; antennae noticeably more incrassate. 



crassicorne 

 Pale in color and more rufous ; elytra often feebly infumate along the 

 apex ; abdomen blackish ; pronotum very densely and distinctly punc- 

 tate nearly like the elytra pallidlllU 



Elytra small, quadrate, distinctly less than one-half longer than the pro- 

 thorax ; body dark, piceous-black in color, the sides of the elytra and 

 base and side margin of the pronotum in basal two-thirds paler. 



alutaceiim 



The Australian species assigned to Amphichroum, with their 

 transverse antennal joints, will in all probability also have to be 

 separated generically. 



P. flavescens n. sp. — Rather broad, depressed, polished throughout, 

 flavate, the a))domen black ; posterior portions of the head piceous ; antennae 

 feebly infumate toward apex ; pubescence very minute, sparse and incon- 

 spicuous. Head one-half as wide as the elytra, slightly wider than long ; eyes 

 convex, well developed ; vertex and front flattened, the two divergent grooves
