112 Mr. F. P. Pascoe on some new or Uttle-Jcnown 



front, with a narrow margin at the side. Elytra elongate, subparallel. 

 Legs short; coxae distant; tibiae smooth externally, dilated at the 

 extremity, and terminated by two or three spurs ; tarsi stout, the first 

 three joints subequal. Abdominal segments equal. Prostemum con- 

 tinuous with the mesostemum. 



I believe this genus will be found to include that portion of 

 Erichson's Pycnomerus which is characterized by its eleven-jointed 

 antennae. Dechomus, distinguished by having eight only, has been 

 recently separated by M. Jacquelin du Yal. The two European 

 species, P. terebrans and P. inexsjpectus, with ten joints, will, there- 

 fore, alone represent the true Pycnomeri, The species described 

 below has very slightly impressed antennarj^ grooves, a character 

 which, among the Pycnomerinae, does not appear to be of generic 

 importance. 



Penthelis^a joorosa. 



P. elongata, subdepressa, rufo-picea ; prothorace fortiter punctato ; ely- 

 tris punctato-striatis. 



Jfab. Brazil (Rio). 



Elongate, subdepressed, reddish-pitchy; head slightly convex in 

 front, moderately punctured; prothorax longer than broad, a little 

 narrowed posteriorly, covered with large and somewhat remote punc- 

 tures ; scutellum indistinct ; elytra coarsely striate -punctate, the striae 

 very narrow, with the punctures oblong; legs smooth, the internal 

 border of the tibiae towards the extremity, especially of the anterior, 

 slightly spinulose ; body beneath pitchy-brown, with large shallow 

 punctures. Length 2 lines. 



Hyberis [Colydiidae]. 



Head short, transverse, immersed in the prothorax nearly to the eyes. 

 Antennae of moderate length, arising beneath the lateral border of the 

 head, moderately thick, ten-jointed, the joints ovate-elongate, setigerous, 

 the first rather incrassated, the third longest, the tenth forming a pyri- 

 form club. Eyes lateral, round, rather prominent. Mentum nearly 

 quadrate. Palpi claviform, terminal joint of the maxillary much larger 

 than the others, shortly ovate, truncate, of the labial oblong-ovate. 

 Prothorax transverse, bisinuated in front, rounded and strongly ser- 

 rated at the side, narrowed behind. Elytra much wider than the pro- 

 thorax, broadly ovate, convex. I^egs moderate ; coxae distant ; femora 

 robust; tibiae fusiform; tarsi short, the basal joint longer than the two 

 following. Abdominal segments nearly equal. 



As the only specimen I have seen of this insect belongs to the 

 British Museum, I am unable to give any account of its oral 

 organs ; but there can be no doubt that it is nearly allied to 

 Ajpeistus, and it would therefore be interesting to know if it be
