Ferruginea ; facie, scutello, post-scutello, metanoti basi, 

 late, mesopleuris, petioloque, flavis ; pedibus rufis ; alis hya- 

 Jinis, nervis stigtnateque nigris. $ . 



Long., 13 mm. 



Head rufous, below the antennae yellow. Mandibles 

 yellow, their teeth black ; palpi rufo-testaceous. The de- 

 pressed front smooth and shining, the sides and lower part of 

 the ocellar region striated ; the upper part of the front with 

 a wide furrow. Face distinctly and closely punctured ; the 

 clypeus much more sparsely and indistinctly punctured. 

 Thorax rufous ; the lower half of the propleurae, the upper 

 part and apex of the mesopleuraa, the base and lower part of 

 the metapleurae more broadly, the space at the sides of the 

 scutellums, the central apical area, and the sides at the apex 

 of the metanotum, black ; a spot on the base of the propleurae, 

 the greater part of the mesopleurae, of the metapleurae, the 

 scutellum, post-scutellum, and the base of the metanotum to 

 the top of the apical slope, yellow. Mesonotum and scutellum 

 sparsely punctured \ the basal half of the median segment has 

 mo areae ; on the apex are three, the central being slightly 

 wider at the top than at the bottom ; pleurae smooth and 

 shining. Legs uniformly rufous. The recurrent nervure is 

 received shortly beyond the middle. Abdomen smooth and

Degithina hectori, sp. nov. 



Capite thoraceque brunneis, flavo-maculatis, abdomine

Antennae black, slightly brownish beneath towards the 

 apex ; the apex of the scape rufous beneath. On the dark 

 mahogany-coloured head, the clypeus, lower part of the face, 

 the front, the ocellar region, and the occiput are black ; the 

 sides of the face broadly, the upper orbits on the inner side 

 broadly — the marks obliquely narrowed from the middle 

 towards the base and apex — and a large mark near the centre 

 of the outer orbits — rounded and slightly narrowed behind — 

 yellow, mixed with chocolate. The face is distinctly, but not 

 very closely, punctured, more closely and distinctly in the 

 middle than at the sides ; the clypeus is sparsely punctured ; 

 the projecting clypeus is smooth, except for a narrow band of 

 minute punctures on the apex ; it is rufous, and fringed with 

 long fulvous hairs. The front and vertex have a few scattered 

 punctures in the middle ; the former is deeply furrowed 

 down the middle. There is a deep furrow surrounding the 

 front ocellus. On the dark-chocolate thorax the following
