notes on the genus Hilipus. 585 



H. apiatus, 01., to which this species may be con- 

 veniently compared, has a narrow prothorax, longer 

 elytra, transversely rugose or ridged (the ridges formed 

 by more or less closely connected granules), and the two 

 basal joints of the funicle equal. Found at Para by 

 M. de Mathan, who collected for M. Bene Oberthiir, to 

 whom I owe my specimen. 



Hilipus angusti colli s. (PI. XVI., fig. 3). 



H. elongatus, fusco-piceus, elytris maciilis mimerosis silaceo- 

 squamosis ornatus ; prothorace fere cylindrico, quam latitudine 

 dimidio longiore. Long. 8 lin. 



Hab. Cayenne. 



Elongate, dark pitchy, the elytra crowded with numerous small 

 round spots of silaceous scales ; eyes rather small, round ; rostrum 

 stout, strongly striate-punctate as far as the commencement of the 

 scrobes ; antennae pitchy ; first joint of the funicle somewhat 

 longer than the second, the remainder transverse ; prothorax 

 almost half as long again as broad, subcylindrical, flattish above 

 and coarsely punctm-ed, the punctm-es divided by raised transverse 

 lines, the middle with a short ridge, each side with a band of 

 silaceous scales ; scutellum punctiform, glossy black ; elytra nearly 

 three times as long as the prothorax, and much broader through- 

 out, the apex broadly rounded ; body beneath dark pitchy, nearly 

 free from scales ; fore-tibiae entire. 



The contour of H. lactarius, but spotted as in H. 

 apiatus. It is the H. angusticollis of Dejean. 



Hilipus tetraspilotus. (PI. XVI., fig. 2). 

 H. eUipticus, aeneus, capite femoribusque nigris ; elytris seriatim 

 punctatis, singulis maculis magnis rufo-fulvis ornatis. Long.

Hah. Parana. 



Elliptic, brassy, head black, closely punctured ; rostrum mode- 

 rately stout, with five more or less distinct, interrupted, raised 

 lines ; antennae ferruginous ; second joint of the funicle longer 

 than the first, the remainder transverse ; prothorax much broader 

 than long, closely punctured, the intervals granulate, each punc- 

 ture with a silvery hair ; scutellum subtransverse ; elytra scarcely 

 broader than the prothorax, gradually rounded at the sides, seriate- 

 punctate, punctures coarse, apex rounded, each elytron with two 

 large reddish-tawny spots — one before the other behind the middle ;
