tlic sides) on the apical margin of the first six abdominal 

 yegments, a small spot on each side of the epipygium at the 

 apical angles, the anterior tibige and tarsi in front, and the 

 base of the intermediate and ])osterior tibite pale yellow ; the 

 aj)ex of the mandibles and the legs pale dull ferruginous ; 

 the antennse fusco-ferruginous, paler towards the apex. 

 Wings hyaline, nervures black, the stigma ferruginous.

 Expedition). 



Type in B. M. 



The difference from typical Myzine in the neuration and 

 antennaj is marked, showing some approach to Iswara, but 

 the ocelli are only very slightly enlarged. In the slender 

 form it resembles Plesia rather than Myzine, the basal 

 segment of the abdomen being somewhat longer and flatter, 

 with a longer petiole than in typical Myzine.

? . Mandibles smooth and shining, with a shallow groove 

 near the inner margin and a very feeble tooth on the inner 

 margin near the apex, the outer margin fringed with sparse 

 ferruginous hairs. Clypeus transverse and extremely short ; 

 head smooth and sliining, quadrilateral, nearly half as broad 

 again as long, the front produced over the base of the an- 

 tennae, forming a broad feebly bilobed prominence. Antenna} 

 smooth, the scape alone with a few fulvous hairs beneath, 

 shining and impunctate ; the first joint of the flagellum 

 narrowed at the base, the second joint fully half as long again 

 as the first. Eyes oblique ; the posterior ocelli very small, 

 placed nearer to each other than to the posterior margin of 

 the head. Thorax and propleuro} smooth and shining ; the 

 pronotum nearly as long as broad, rounded at the anterior 

 angles, with a few setigerous punctures along the lateral 

 margins ; mesonotum with two longitudinal sulci on each 

 side, very short, not more than one-third of the length of the 

 pronotum ; the scutellum as long as the mesonotum ; mcso- 

 ])leur£e sparsely punctured. Median segment shining at the 

 base, with a median longitudinal sulcus finely crenulate at 

 the posterior angles, longer than the mesonotum, truncate 

 posteriorly and transversely striated on the surface of the 

 truncation ; the sides of the segment concave and finely 

 obliquely striated. Abdomen shining, very sparsely punc- 

 tured ; tiie petiole of tiie basal segment a little longer than 

 broad, the apical segment almost impunctate, with a very
