tinguish it from Colpochila except the conic form and unusual 

 brevity of the apical joint of the labial palpi and the somewhat 

 peculiar labrum (slightly approaching that of Glossocheilifer ), 

 which viewed from above appears as a lamina projecting to a 

 moderate degree from the lower part of the vertical front face of 

 the clypeus, and having its free outline broadly rounded. In the 

 unique male before me the abdomen is remarkably short but this 

 may possibly be the result of distortion merely, and I also observe 

 that the bristles forming the apical fringe of the hind tibiae are 

 unusually short and thick. 



A. color atus, sp. no v. Brevis, sat latus ; sat nitidus ; supra sat 



glaber sed prothorace pilis timbriato, subtus in sternis 



femoribusque pilosus ; rufus, elytris nigro-piceis ; clypeo 



subtil ius crebrius, capite postice magis fortiter, prothorace 



ut clypeus sed minus crebre, elytris crebrius fortiter, pygidio 



subtiliter sparsim, punctulatis ; clypeo antice rotundato sat 



fortiter reflexo; prothorace postice marginato, fortiter 



transverso, antice fortiter angustato, angulis anticis acutis 



minus prominulis posticis (superne visis) fere rectis, basi 



utrinque vix sinuata ; elytris parum distincte striatis (striis 



geminatis), interstitiis planis; tarsorum posticorum articulo 



basali quam 2^*^ vix breviori. Long., 5 1.; lat., 2^ 1. 



This small species is notable for its coloring, the whole insect 



laeing of a somewhat full red color except the elytra which are 



black (or nearly so), with a little tendency to rufescence about 



the shoulders. 



S.W. Australia; Eyre's Sand Patch. 



COLPOCHILA. 



C. Roei, Burm., is certainly, I think, identical with 

 C. crassiventris, Blanch. The latter is the older name. 



PETINOPUS (gen. nov. Sericoidarum).
