Poclontia Dalmani. 



P. elongata, parallela, posticc vix attenuata, pallide picea, nitida ; 

 thorace basi biimpresso, disco medio longitudinaliter sulcato, 

 utrinque late foveolato, antice utrinque (a margine apical i ad 

 foveam lateralem) longitudinaliter impresso ; elytris ante medium 

 gibbosis, fortiter punctato-striatis, r.igro-piceis, flavo irroratis, 

 singulatim plaga basali, fascia lata prope medium alteraque ante 

 apicem flavis, punctis super partes flavescentes piceis ; femoribus 

 posticis modice incrassatis. 



Long. 6 lin. 



Hob. Lombok, Siam. 



Poclontia rufo-castanea. 



P. subelongata, convexa, subtus cum antennis (bis basi excepta) 

 nigra, nitida, corporc supra et thorace infra rufo-castaneis ; thorace 

 basi obsolete biimpresso ; disco utrinque profunde foveolato ; ely- 

 tris ante medium gibbosis, distincte sed tenuiter punctato-striatis ; 

 femoribus posticis modice incrassatis. 



Long. 6 lin. 



Hob. India. 



This and the preceding insect were originally described by 

 me as varieties of P. 14<-punctata (Journ. Ent. i. p. 451). Sub- 

 sequent investigation, however, has convinced me that they are 

 entitled to the rank of distinct species. 



Poclontia congregata. 



P. oblonga, convexa, pallide rufo-piceo, nitida, capite elytrisque ful- 

 vis ; his ante medium gibbosis, punctato-striatis, maculis numerosis 

 rufo-piceis, prsesertim ad latera et apud suturam congregatis, or- 

 natis ; thorace ad latera foveolato, basi breviter bisulcato, ante 

 medium utrinque longitudinaliter impresso ; femoribus posticis 

 modice incrassatis. 



Long. 5\ lin. 

 Hab. " ?. 



Subfam. Gallerucin.e. 



Genus Dircema, Clark. 



The Rev. H. Clark, in his description of Dircema cinctipennc, 

 has included five or six closely allied but distinct species : their 

 diagnoses (together with those of several others entirely new) I 

 have given below. The males of Dircema may be known from 

 having the apices of the intermediate tibia? armed with a short 

 tooth or acute process; both sexes have the anal segment of the 

 abdomen notched ; in the $ this notch is large and angular, its 

 extreme apex being impressed with a distinct fovea; in the $ 

 the notch is smaller, somewhat variable in shape, although usu- 

 ally linear, and the apical fovea is obsolete.
