l(i(i. Aderpas lineolatus (Chevr.). 

 Guld Coast. This species, placed in Acdiithocinus in tlie IVIunicli CatalofTue, 

 agrees in all generic characters with the other species of Aderpas. 



101. Aderpas griseus Thorns. 

 Kuilu. 



162. Aderpas subfasciatus sp. nov. 



A. piceo-uiger ; antennis, abJomiue peJibasque rufesceutibus ; griseo-albo- 

 pubescens. Capita et prothorace fere aequabiliter pubescentibus ; antennis articulis 

 basi griseis ; scntello triaugnlare, lateribus rotnndato : elytris basi grosse, apicem 

 versns minute pnnctatis, albo-variegatis, fascia transversa, el}1;ris commuui. aute- 

 mediana, sat Inconspicua, et maculis dnabiis postmedianis transverse dispositis 

 olivaceo-brunneis ; infra minutissime densissime pnnctatus. 



Long. 10| mm., elytr. 7^, lat. :ii. 



This species is closely allied to ^-1. (/rUeas Thorns. ; but it may be known by the 

 dark pitchy colour of the boily, with the antennae, legs and abdomen reddish, by the 

 even pabescence of head and prothorax, and by the more slender and less convex 

 elytra with a iliiferent style of markings. The elytra have a transverse olivaceous 

 brown band before the middle, abbreviated at the sides, and two spots of the same 

 colour behind the middle of each elytron ; the white spots are very small, whilst 

 A. f/rixeus Thoms. has two median and one anteapical spot somewhat enlargt^d. 

 A. lineolatus (Chevr.) is also closely allied, and differs chiefly in the fulvous 

 grey pubescence, in the co.arser punctuation of the elytra, and in the apex of the 

 latter being feebly emarginate, with the outer angles somewhat produced. 



163. Aderpas punctulatus sp. nov. 



A. brunneo-niger, sparsim griseo-albo-pnbescens. Antennamm scapo articulo 

 tertio jiaulo lougiore; prothorace pnnctulato, lateribus snbrotundato, inermi; scutello 

 snbrotundato, apice medio minute angnlato, albo-marginato ; elrtris densissime 

 grosse puuctatis, minute albo-maculatis, maculis uonnnllis post scutellum et ]JOst 

 medium sitis parnm conspicuoribus ; tibiarnm ajncibus tarsisque nigro-pilosis. 



Long. 7 mm., elytr. 5, lat. 2^. 



Base of the antennae and the tibiae more reddish than the remainder of the 

 body. The pubescence is rather sparse, and forms indistinct and very small white 

 spots on the elytra ; one or two of the s]5ots before the miildle of each elvtron, and 

 some more beyond the middle and at the sides are more conspicuous. The very 

 dense punctures of the elytra are arranged in rows here and there ; one regular 

 row at the suture extends from the middle to the apex. 



Hab. Knilu. 



The dense punctuation of the elytra is the principal character, by which this 

 small form may be easily distinguished from the other species of the genus hitherto 

 known.
