Goleopterolofjical Notices, VI. 7i)l 



1. P. iiotatus Lee.— Pioc. Acad. Nat. Sci., Phila., 1855 p. 276 (Xylo- 

 philus). 



The unique type of this species is not before me at present, but 

 from a sketch made some years ago, the posterior pale spot of the 

 elytra is situated at about apical third ; this, in conjunction with 

 LeConte's statement " capite thoraeeque opacis, confertira punc- 

 tulatis," and the fact that the type was taken in Habersham 

 County, in the extreme northeastern and submountainous parts 

 of Georgia, a region zoologicall3^ altogether distinct from the 

 tropical southern tip of Florida, leads me to believe that notatus 

 will prove to be quite distinct from amicus. The generic diagno- 

 sis is taken from the latter. The type of notatus is 1.4 mm. in 

 length ; width 0.05 mm. 



2. P. amicus n. sp. — Oval, convex, polished, rufo-piceous, the legs and an- 

 temite pale fla\ate; elytra black, graduallj' pale toward apex, each with a 

 large irregular and transversely reniforni spot at basal fourth, extending at the 

 sides to the humeri, and another large subquadrate spot at apical fourth, of 

 pale flavo-testaceous; pubescence moderately long, rather close, coarse and 

 distinct. Head feebly convex, shining, subimpunctate; eyes separated by 

 about one-half more than their own width; antenuie barely two-fifths as long 

 as the body, gradually incrassate through the six or seven outer joints, third 

 and foui'th equal and very slender, eleventh moderately large, compressed, 

 obliquely and abruptly pointed. I'rothorax slightly narrower than the head, 

 transverse, fully one-third wider than long, the sides gradually and very 

 feebly convergent from near the apex to the base, the latter margined through- 

 out the width with an extremely fine elevated bead; apex broadl}^, feebly ar- 

 cuate; disk rather linely but strongly, moderately closely punctate. Elytra 

 about one-third longer than wide, nearly twice as Avide as the prothorax, par- 

 allel and broadly arcuate at the sides, semi-circularly rounded at apex; humeri 

 rounded but somewhat widely exposed at base ; disk not evidently impressed 

 near the humeri, convex, not coarsely but strongly, rather sparsely punctate, 

 the punctures becoming verj' fine and relatively remote toward apex. Abdo- 

 men convex, shining, the legs slender. Length 1.3 mm.; width 0.65 mm. 



Florida (Biscayne Bay). Hubbard and Schwarz. 

 The type, which is one of two specimens, is a female and is 

 somewhat mutilated. 



YANOIVUS n. gen. 



The body in Yanonus is moderately elongate and subparallel, 

 clothed with ver}' short decumbent pubescence, the head trans- 

 versely truncate and moderately elevated at base, with the eyes vari- 

 able but always semi-nude, the setoe being extremely minute; they
