154 Mr. H. W. Bates on the 



curious abnormal structure presented by Ohrium and many 

 allied genera. The genus has much general similarity to 

 Ceresiunij except in the long slender legs and abruptly clubbed 

 femora. The exserted anterior coxfe bring it, so far, within 

 the definition of the Gracilides (Lacord.) ; but the tightly 

 closed middle sockets exclude it from that group. 



Stenodryas clarigera^ n. sp. 



/S. angusta, fulvo-testacea, sparsira pubescens ; antennarum scapo, 

 femorum clava tibiarumque apice piceo-nigris ; capite supra 

 rugoso-punctato ; thorace siibsparsim punctato, subopaco, plaga 

 elongata mediana Isevi, disco utrinque insequah ; eljiris passim 

 sequaliter discrete punctatis. Long. 4| lin. c? .

Stenygrixum, nov. gen. 



Facie generis Stenygrce, gen. Ceresio affine. Thorax cylindricus, sed 

 femoribus abnipte valde clavatis et tibiis intermediis fortiter cur- 

 vatis. Corpus elongatum, sparse setosum. Caput, cum oculis 

 convexis, thorace paulo latius ; palporum articulo ultimo dilatato 

 triangulari, maxillaribus elongatis. Antenyue robustse, liHformes, 

 articvilis o^-lO"" apice extus productis, articulo quarto parvo, quam 

 tertio vel quinto dimidio breviore. Coxce anticse globosae ; pro- 

 sternum inter coxas modice angustum ; mesosteruum planum. 



This new genus is closely allied to Ceresium, and still more 

 so to the Australian genus Betheh'um, from which latter it 

 differs in the cylindrical (instead of cordate) thorax and less 

 hirsute antennse. The elytra are similarly coloured to the 

 Tropical- American genus Stenygra^ and they are also distin- 

 guished by two oblique depressions on each, one near the 

 suture towards the base, and the other on the posterior part of 

 the disk. The legs are rather short and stout ; the femora of 

 all abruptly and strongly clavate. The intermediate tibiae are 

 strongly bent outwards, as it appears, in both sexes. The 

 antennte in the (J are a little longer (in the $ a little shorter) 

 than the body. 



Stenygrinum quadrinotatum^ n. sp. 



8. elongatum, convexum, sparse setosum, rufo-castaneum ; elytris 

 medio fusco-nigris, maculis duabus utrinque discoidalibus flavo- 

 testaceis, una paulo ante, altera apud medium ; thorace juxta 

 apicem constricto, ante medium paululum dilatato, subcrebre baud 

 profunde punctulato, punctis majoribus rugulisque intermixtis, 

 linea dorsali Isevi ; elytris punctis pihferis discretis, versus apicem 

 minutissimis. Long. 5 lin. d ? • 

 Ipongi ; three examples.
