2. — PolyyTia brevipen^iU. 



Polyuria hrevipennis Pic, Bull. Soc. Ent. Fr., 1902, pp. 166, 167. 



Elongate, shining ; brown oi- ferruginous, the eyes black, the prothorax 

 and the lateral portions of the elytra sometimes infuscate, the under surface 

 piceous in the darker individuals, the antennae and legs ferruginous or testa- 

 ceous ; above and beneath closely, moderately coarsely punctate, thickly 

 clothed with rather long, decumbent, cinereous hairs. Eyes very large, coarsely 

 facetted, narrowly separated in ^ . Antennae strongly serrate from joint 3 in 

 <? , serrate from joint 4 in $ . Prothorax transverse, rounded at the sides 

 anteriorly, the latter converging and slightly sini^ate posteriorly, the three 

 foveae on the disc large, shallow, the anterior one strongly transverse, the 

 narrow space between the two basal impressions sometimes with a short, 

 smooth longitudinal carina in the centre. Elytra moderately elongate, sub- 

 cylindrical, much wider than the head and prothorax, the suture depressed 

 near the apex. Beneath closely, the proJ)leura densely, punctate. Length 4f-7, 

 breadth 1^-2^ mm. ( ^ ? .) 



Hah.: Brazil {BolU -. type in coll. Pic; Lacerda, Mus. Brit.), 

 Pernambuco (Gomielle), Bsdnaj, San Antonio (Fry), Eio Grande do Sul 

 (Br. Iliering) ; Argentina, Ocampo on the Eio Las Garzas ( Wayner') . 



Ten specimens, varying a good deal in size and colour : the two 

 from Bahia have the antennae (the third joint included) more 

 strongly serrate than the others, and the eyes more approximate, and 

 are therefore assumed to be males. More closely and less coarsely 

 punctate above than P. lateralis and P. cmx-rufa, the three prothoracic 

 foveae shallower and the elyti'a much less elongate than in P. lateralis, 

 the elytra without definite markings, this last-mentioned character 

 separating the present species from the three other members of the 

 genus. Pic mentions a variety from Jatahy with the punctuation 

 more scattered on the disc of the prothorax : this he names hrunnescens. 



Laccodbrus, n. gen. 



Head short, deeply inserted into the prothorax, obliquely narrowed behind 

 the eyes, with distinct frontal groove, the epistoma very little longer than the 

 labrum, the antennae inserted beneath the sub-angularly raised orbits, short, 

 sub-serrate or serrate ; eyes large, distant, rounded, entire ; maxillary palpi 

 stout, the terminal joint sub-triangular, that of the labial pair oblong-oval, 

 truncate at tip ; mandibles cleft at apex ; prothorax short, sub-quadrate, with- 

 out lateral carina, margined at the base, with two large foveae on the disc ; 

 scutellum small ; elytra long, confusedly punctate, widened posteriorly in $ , 

 the epipleura not reaching the apex ; anterior coxae conical, exserted, con- 

 tiguous, the cavities open behind ; intermediate coxae narrowly separated ; 

 legs rather short, slender ; tibiae with niiuute spurs ; tarsi narrow, the penidti-
