t'le licad broadly cmnr^inate posteriorly ; pronotum narrowed 

 anteriorly, the pot^terior angles elevated, subtuberculate ; 

 uiesonotum short. A depressed transverse line, smooth and 

 .shinini:, at the base of the scutellum. Median segment sub- 

 (juadrate, flat above, obliquely truncate posteriorly, rugose 

 aibovc, the lateral margins raised, forming carinai ; a median 

 carina from the base, extending along both the dorsal surface 

 and the surface of the truncation to the apex, a carina on 

 cacli side converging from the base and meeting before the 

 truncation, forming an equilateral triangle, the space included 

 longitudinally striated ; the surface of the truncation trans- 

 versely striated. Abdomen sub|)etiolate, sharply pointed at 

 the apex ; shining, the segments almost smooth at the base, 

 linely punctured along the apical margins. 



Opaque black ; the median segment metallic blue-green ; 

 the abdomen shining bronze-green ; the mandibles, the scape 

 and two apical joints of the antennaj, the mesopleura?, the 

 i-ides of the median segment, the prosternum, the base of the 

 first abdominal segment, and the legs ferruginous. The 

 femora and coxae marked with green-bronze above. Wings 

 hyaline, crossed by two fuscous bands, one crossing the base 

 of the discoidal cell, the other broader and close to the apex.

'i lie joints ot the maxillary palpi are much longer in this 

 species than in coruscans \ the three aj>ical joints are elongate 

 as in the genus Aij/ielotoma, Westw. 



Auchenophorus fulvicornisj sp. n. 



^ . Head opaque, finely reticulate, the eyes converging 

 towards the vertex, the ocelli placed between the eyes near 

 their apex. Antennae as long as the head and thorax united, 

 the scape short, the two apical joints stouter than the others. 

 The three terminal joints of the maxillary palpi much elon- 

 gated. Pronotum short, much depressed anterioi ly, broadened 

 iiosteriorly, the angles prominent but not spined. J\leso- 

 iH^tum finely reticulate, opaque, not reaching the posterior 

 uiargin of the tegulae. Median segment short, flat above, 

 obliquely truncate posteriorly, the margins of the dorsal 

 surface raised, forming an enclosed space, rounded at the 

 apex and longitudinally striated within; the surface of the 

 truncation obliquely striated at the base, smooth at the apex. 

 Abdomen subpetiolate, shining, the two basal segments 

 fcuiooth, the rest very finely and closely punctured.
