Hal. Old Calabar. 



This species strongly resembles the West African A. 

 disparilis in size and form, but is easily distinguishable 

 by its black legs and short rounded clypeus. It is more 

 cylindrical and much less hairy beneath than the other 

 species of this group and the puncturation of the elytra 

 is more regular. 



The following new species is the representative of the 

 third type of claw-structure already referred to : — 



A. calcarata, sp. n. 



Breviter ovata,flavo-testacea; capite laevi, vertice bimaculato, clypeo 

 impunctato, margine valde reflexo ; prothorace parvo antice fortiter 

 contracto, parum punctato, medio linea impressa ; scutello brevi 

 obtuse angulato, laxe punctato, apice profunde impress© ; elytris 

 irregulariter punctato-striatis, versus extremitates ampliatis ; corpore 

 subtus cum pedibus longe ac dense villosis, tibiis anticis fortiter 

 bidentatis, posticis brevibus triangulariter crassatis, extremitatibus 

 latissimis, calcaribus duobus longis singulo armatis ; tarsis elongatis. 

 Long. 16 mm. 



^ . Corpore brevi ; clypeo late ; unguiculis omnibus simplicibus. 



5 . Corpore magis elongato ; clypeo minus lato ; pedum anterio- 

 rum unguiculis externis apice emarginatis. 



Rah. South Africa, Cape of Good Hope {Eeiche). 



This species occupies an isolated position in the genus 

 by its many structural peculiarities. It is shorter and 

 more ovate than any other testaceous species known to 

 me. The head and clypeus have only a few scattered 

 punctures. The thorax is broad behind and strongly 

 lobed in the middle. The elytra are coarsely punctured, 

 the punctures, which are sometimes confluent, being 

 chiefly arranged in irregularly placed striae. The hind 

 tibise are short, very slender at the base and regularly
