ACHTHOPHORA. 



Achlhophora, Newman, The Entom. i. 292. 

 Stegenus, Pascoe, Trans. Ent. Soc. ser. 2, iv. 104. 

 Caput antice supra angustius ; tuberibus antenniferis validis, 

 crectis, contiguis, apice intus prodiictis. Oculi parvi, ore 

 remoti. /intennce corpora vix longiores, articulis (ultimo 

 excepto) cylindricis, quatuor basalibus aliquando hirsutis; 

 scapo mediocre ; articulis tertio et quarto longioribus ; 

 caeteris brevioribus et gradatim decrescentibus, ultimo subu- 

 lato, curvato. Prolhorax cylindricus, utrinque dente minuto 

 instructus, capite baud latior. Elytra subdepressa, apicem 

 versus sensim angustiora, humeris supra producto-lobatis. 

 Pedes breviusculi, intermedii minores ; tarsi aequales. Vro- 

 sternum elevatum. Mesosternvm productum. 

 When I proposed Stegenus I stated that it differed from Achtho- 

 2^hora chiefly in its antennae, the first four joints being clothed 

 with stiff hairs instead of only the apex of the fourth. In other 

 respects it agrees so closely with Achthop/tora, that after a re- 

 newed comparison, I think it is desirable to unite them. Achtho- 

 phora alma has the prothoracic spine tolerably well developed ; it 

 is smaller in A. tristis, the type, and least of all in A. dactylon, in 

 which it is scarcely noticeable. Mr. Newman considers that 

 A. alma may be only a variety of A. tristis, but the typical spe- 

 cimens, which are the only ones I am acquainted with, do not in 

 my opinion justify such a conclusion. A. dactylon, which is appa- 

 rently rare in Borneo, seems to be a common species in Penang. 

 The other two are from Manilla. My original specimen was en- 

 tirely of a dark brown, except the apex of each elytron, which 

 had a peculiar finger-shaped patch of buff, but all those from 

 Penang have numerous small very clear spots of yellow on the 

 elytra, and some indications of paler or more greyish spots else- 

 where, particularly on the prothorax.
