28 Prof. J. O. Westwood's descriptions 



turn is deeply notched in front, with the lateral lobes 

 rounded ; it is very hairy, and the labial palpi (of which 

 the apical joint alone is visible from the outside) are 

 slender (fig. Ic). The cui'ious digitation of the posterior 

 tibia3 (whence the name of the genus) aj) pears, from the 

 corrected description given by M. Lacordaire, to be con- 

 fined to the female sex. The genus is well characterized 

 by the small flat glabrous elytra, having the suture and 

 the lateral margins elevated into strong cariutB. The 

 following is the description given by Mr. Blanchard of the 

 type species of the genus : — 



Calometojjus senegalensis, Blanch. 1. c. 



Niger, capite medio rufo, prothorace omnino rufo seu 

 obscuro ; scuto (scutello) rufo nigro-limbato ; elytris fulvis, 

 margine externo nigro ; sutura carinaque laterali elevatis, 

 pygidio nigro rugoso maculis fulvis binotato, abdomine 

 nigro, maculis lateralibus albis; pedibus fulvis, tarsis tibia- 

 rumque apice nigris. Variat femina elytris fere omnino 

 nigris. 



Long. 1.3—15 mill. 



According to M. Lacordaire the male is dull black 

 above, shining beneath, and the female fulvous, with the 

 forehead, the sides of the elytra beyond the middle, the 

 breast, abdomen and tarsi black ; these colours possibly 

 being variable in both sexes. As the specimens which 

 I have seen from Nyassa are uniform in their colours, 

 I have not hesitated to consider them as forming a dis- 

 tinct species from the Senegal one. 



Genus Valgus, Scriba. 

 Valgus furcifer, n. sp. (PL I. fig. 2.) 

 Niger punctatissimus luteo nigroque squamosus, pronoto 

 subquadrato, antice supra caput parum rotundato-producto, 

 angulis anticis lateralibus rotundatis, posticis extus parum 

 acute productis; disco in medio longitudinaliter paullo 

 canaliculato, tuberculisque duobus dorsalibus in medio 

 instructo, margine postico curvato et ad basin scutclli 

 rotundatim-producto : elytris latis subquadratis, lateribus 

 deflexis, dorso subplanis : basi fulvescentibus, singulo prope 

 scutellum nigro 4-striolato, striolis curvatis : fascia abbre- 

 viata transversa nigra pone apicem scutelli ; dimidio postico 

 elytrorum lutescenti, fascia transversa pone medium nigra, 

 postice prope suturam extensa; plaga lutescente transverse- 

 ovata apicali in singulo elytro relicta, maculam uigram
