16. ACANTHOSOMA BINOTATA. 



Tcslacea,lon(/i-ovala,fuscopunctala; caput elont/alttm, antlce f/labruin ; 

 anleniue gracilcs, corporis dimidio breviores ; thorax fascia f/labra 

 anlice testaceo pallida marginala, villa lateribusque pallida tcslaceis, 

 spinis longis subrecvrvis ; sciilelliDii testaceo pallido univiltalum, 

 plagis duabui laleraiibus apiccqne fuscis ; venter fusco maciilariler 

 bivitlaliis, spina coxas medias attingente ; al<e anticce macula pallide 

 testacca fusco inarginata. 



Testaceous, elony:ate-oval, roiicflily punctured ; punctures Lrown. 

 Head elouj^ate, smooth m front; middle lobe hardly extending beyond 

 the lateral lobes. Eostrnsn extending to the hind coxa? ; lip black. An- 

 tenmc slender, less than half the length of the body ; juims successively 

 increasing in length ; first extending a little in front of ilie head. Thorax 

 iu front with a smooth band, of v.'liich the fore bonier is a curved pale tes- 

 taceous line; sides and a slender stripe also pale testaceous ; hind angles 

 forming two long acute slightly recurved spines. Scutcdlum with a slender 

 pale testaceous stripe, on each side of which there is a brown patch ; tip 

 also brown. Pectoral keel well developed. Abdomen beneath slightly 

 keeled, with two incomplete macular brown stripes; spine extending to the 

 middle coxee. Fore wings clouded with brown around a smooth transverse 

 pale testaceous spot in the disk ; membrane cinereous. Length of the 

 body ;5:f lines. 



It has most affinity to A. punctata, from which it may be distinguished 

 by the spines of the thorax.

17. ACANTHOSDMA ASPEEA. 



Testacea, longi-ovata, nigra punctata ; caput elongattim, loho medio lohox 

 lalerales perpaullo superanle ; thorax spinis duabas ru/is loni/is 

 vatidis vix recurvis ; xienter subcarinalus, coxas medias atliugens ; 

 pedes sat graciles ; membrana cinerea.
