PHYTOPHAGOUS COLEOPTERA FROM MENTA WEI 135 



underside flavous, legs rather darker, the posterior tibiae with 

 a stout spur, the first joint of the posterior tarsi, as long as 

 the following two joints together, prosternum extremely narrow, 

 the anterior coxal cavities closed. 



Hab. Sipora, Sereinu, Si-Oban. 



This species makes the impression as being immature , on 

 account of the very faint elytral bands, which in some specimens 

 are scarcely visible , but there is no difference in this respect 

 amongst the individuals before me , so that it is no doubt the 

 normal colouring of the insect, it is nearly allied to A. dimidiata, 

 Baly. 



12. Acrocrypta fulvicollis , Jac. — In my original description 

 of this species (Notes Leyden Mus. 1884) I have given the an- 

 terior coxal cavities as open , this is either incorrect or if not , 

 the species does not belong to Acrocrypta in which the cavities 

 are closed. There was only a single specimen before me at the 

 time, which is contained in the Leyden Museum, so that I cannot 

 verify my statement now ; the specimens sent to me by the 

 late M. Duvivier from the island of Bodjo and which he looked 

 upon as a variety of my species represent probably another 

 form, as the elytra are very strongly punctured and the antennae 

 are of different colour. I give here the description. 



13. Acrocrypta Duvivieri, sp. n. — Fulvous, the antennae (the 

 basal joints excepted) black, thorax finely punctured, elytra 

 violaceous, strongly and closely punctured. 



Length 2 lines. 



Head impunctate , fulvous , frontal tubercles small , clypeus 

 triangular, antennae black and pubescent, the lower three joints 

 fulvous, the following ones broadly and gradually dilated, tho- 

 rax strongly transverse, three times broader than long, the sides 

 nearly straight, narrowly margined, the anterior angles obliquely 

 thickened, the posterior margin broadly produced at the middle, 

 the surface very finely and not very closely punctured, scutellum 

 fulvous, elytra very strongly and closely punctured, the inter- 

 stices slightly rugose and minutely punctured, underside and 

 legs fulvous.
