596 SEERICORNIA. 



Dicranopselaphus is extremely closely allied to Uctopria, Lee, but differs from it in 

 the dilated and lobed fourth tarsal joint, and the bi-appendiculate apical joint of the 

 maxillary palpi. The thorax and elytra are, as in Ectopria, very peculiarly sculptured. 

 The antenna? are pectinate in the males and serrate in the females. The general 

 structure of the mouth-parts, antennae, &c. is very beautifully illustrated by Guerin. 



a. Antenna; ( $ ) pectinate from the fourth joint, the pectinations arising from the 



apex of each joint ; elytra with pale linear markings. [Furcipalpus, Guer.] . lesueuri. 



b. Antennae ( ^ ) pectinate from the third joint, the pectinations arising from before 



the apex of each joint. [Dicranopselaphus, Guer.] 



a'. Antennae black, with the two basal joints yellow ; elytra almost unicolorous . rufescens. 



V. Antennas black, with the two basal joints reddish-brown*; prothorax ferru- 

 ginous, with a black patch on the middle of the disc in front, the basal 

 impressions shallow; elytra with two broad angulated, transverse fasciae, 

 connected laterally, and the apical margin, broadly, testaceous pictus. 



c'. Antennae black, with the apical two or three joints testaceous or flavo-testa- 

 ceous ; prothorax with deep basal impressions ; elytra with two very narrow 

 angulated, transverse fasciae, connected laterally, the anterior one not reaching 

 the suture, and some lines at the sides, testaceous, these markings only clothed 

 with pallid pubescence venosus. 



d'. Antennae testaceous, the basal four or five joints sometimes slightly infuscate ; 

 prothorax with deep basal impressions ; elytra very much as in D. venosus, 

 but with the pallid pubescence extending over a great part of the surface . . flavicornis.
