90 PIIILICUS DIALLOIDES. 



lateral! fere obsoleta. Elytra cuueiforraia , apice extus spi- 

 uosa. Frosternum transversuni , elevatum ; mesosternum haud 

 productum. 



I am reluctantly compelled to propose a new gene- 

 ric name for the species described below, and which 

 at first sight 1 did not hesitate to refer to Diallus\ it 

 differs, however, in all the characters which separate 

 that genus from Cereopsius , while from the latter it is 

 distinguished by the form of the prothorax — /, e. the 

 absence • of the transverse ridge and of the lateral 

 spine , and in the mutic mesosternum. 



Philicus dialloides^ sp, n. 



P. niger, subnitidus, prothorace basi lateribusque niveo- 

 pilosis, elytris maculis sex majusculis, pilis uiveis formatis, 

 notatis. — Long. 4 lin. 



Black and somewhat glossy; sides and base of the pro- 

 thorax and six largish spots on the elytra formed of den- 

 sely set snow-white hairs; numerous hairs also covering 

 the face ; top of the head and disc of the prothorax pu- 

 bescent ; scutellum semicircular ; elytra wedge-shaped , finely 

 punctured, a raised dorsal line terminating at the apex ex- 

 ternally in a prolonged apiculus ; body beneath delicately 

 pubescent , gradually becoming courser at the sides ; fifth 

 abdominal segment with a well-marked spine on each side 

 at the apex; metathoracic epimera carinated. 



Of three specimens before me two have the prothorax so 

 covered with hairs as to leave only a part of its disc bare 

 or apparently so , the pubescence being only visible under 

 a lens. The fifth abdominal segment is apiculate in 

 all , and is probably characteristic of the male sex.
