portion bent downwards. The portion of the margin on which the 

 teeth are situated might perhaps be more correctly described as a 

 very broad apical margin. Clypeus shining, depressed and trans- 

 verse, deeply depressed on the middle of the apical margin giving 

 the appearance of a narrow emargination with a low tubercle on each 

 side at the base of the emargination. The maxillae are slender, the 

 galea small with the usual dividing membranous line rather indis- 

 tinctly marked ; the first joint of the maxillary palpi is very short, 

 the three apical joints rather longer and more slender than the 

 second and third ; the labial palpi are four-jointed, the basal joint 

 much the longest ; the labrum is short and transverse, broadly 

 truncated and ciliated at the apex, expanding from beneath and from 

 the angles into a depressed, subconcave and rounded process, pro- 

 jecting far beyond the true apical margin. Antennae about as long 

 as the head and thorax without the median segment, nearly as far 

 from each other at the base as from the eyes, the six apical joints 

 arcuate. Head, thorax and sides of the abdomen with thin grey 

 pubescence, cinereous on the front. Head finely and very closely 

 punctured, with an obscure, longitudinal, frontal carina not reaching 

 the base of the clypeus. Pronotum narrower than the head, short and 

 narrowed anteriorly, the anterior margin slightly raised. Mesonotum 

 and median segment closely and finely punctured ; scutellum shining 

 and sparsely punctured, slightly raised above the mesonotum. 

 Median segment rounded, with a faintly-depressed line from the 

 base not reaching the apex ; a short, deeply-impressed, longitudinal 

 sulca on each side at the apex. Abdomen elongate, nearly half as 

 long again as the head and thorax combined, shining and very 

 sparsely punctured ; the first segment with a deep sulca from the 

 base to the middle ; the segments are not constricted at the base. 

 Hypopygium narrow and rather long, rounded at the apex, the sides 

 almost parallel. 



Black ; the mandibles, except the margins very narrowly and the 

 apex, the clypeus, a large triangular spot between the eye and the 

 base of the antenna, an oblique spot above the base of each antenna, 

 a small spot on the inner orbit near the summit of the eye, the 

 cheeks with a narrow continuing line broadly interrupted in the 

 middle on the posterior margin of the head, the margins of the 

 pronotum narrowly interrupted in the middle, the anterior margin 

 broadly interrupted on the sides, a spot on the disc of the mesonotum, 

 a curved line above the tegula?, an irregularly-curved band on the 

 mesopleurse, a spot before the base of the intermediate coxae, a large 

 spot on the scutellum and a small spot at tlie anterior angles, a line 

 on the postscutellum narrowly interrupted on the sides, a broad 

 longitudinal and slightly oblique band on each side of the median
