NOTES ON CICINDELIDM AND CARABID^, AND DESCKIPTIONS 

 OP NEW SPECIES (No. 16). 



BY H. W. BATES, P.L.S. 



Ctenostoma ebukatum, 11. sp. 



Ni(/errimii7n, nitidum ; elytris hiimeris distinctis^ 2'^^^^^^^ ''^^^ dila- 

 tatis nee injlatis, usque ad apicem scahroso-punctatis, nullo viodo rugoHis ; 

 fasciola curvata prope hasin, alteraque pone medium, alb is, fere impunc- 

 tatis. Long. Q\ lin. $ . 



Very similar in colours and form to Ct. luctuosuni ; body above 

 and legs clothed, as in that species, with very long, erect, black bairs. 

 Distinguished by its basal elytral fascia, which is narrow, and curves a 

 little from the shoulder towards the suture, which it does not reach. 

 The median white fascia is similar to that of Ct. luctuosum, but does 

 not touch the lateral margin, and is narrowed and hooked at its termi- 

 nation near the suture ; the apex of the elytra is narrowly bordered 

 wdth whitish. In form, the apex (in ? ) is rounded and dehiscent at 

 the suture ; the surface of the elytra is very coarsely scabrose-punctate 

 without transverse wrinkles, and the punctuation continues, but much 

 less strongly, to the apex. The antennse are tawny, with pitchy marks 

 on the first four joints. The forehead is coarsely punctured, and 

 clothed with hoary hairs. 



Taken by Mr. Rogers in the interior of S. Brazil. 



In Mr. W. AV. Saunders' collection, and my own. 



CiCINDELA DITISSIMA, U. sp. , 



L(ste viridis, capite tlwraceque creherrione subtilifer scahroso-punc- 

 tatis, opacis ; elytris velutino-opacis, sutura Uneaque siih-marginali 

 nitidioribus, ut7'inque vitta mediana Jlavo-ochracea ; lahro Jlavo, nigro- 

 marginato, in utroque sexu elongato, antice truncato, valde tridentoto, 

 dente mediano robusto, apice bifido. Long. 7^ lin. ^ ? . 



Approaches nearest C. aurofasciaia, but much more elongate and 

 narrower. The head and thorax are much more finely shagreened 

 than in that species, and the labrnm differs in form fi'om all the 

 species of the group, being only 5 -dentate, with the lateral tooth on each 

 side broad and scarcely prominent, and the three apical teeth project- 

 ing from a straight anterior truncature of the organ ; tliey are very 

 much dfflexed in the ? , and the middle one is long and bifid at its 

 apex. The head is broader behind the eyes, and more exserted than 

 in C. aurofasciaia. The thorax is very similar in form to the same 

 segment in that species, but is narrower than the head. The elytra are.
