flagellutn at base and apex brownish beneath. Face closely, 

 the clypeus more sparsely punctured ; palpi pale yellow ; 

 labrum fringed with long fuscous hair. Vertex below the 

 ocelli closely transversely punctured; front smooth and 

 shining. Mesonotum closely punctured. Scutellum not dis- 

 tinctly depressed at base and apex, its keels sharp and extending 

 to the base of the apical third and depressed on the inner 

 side ; scutellum bifoveate at the base. Basal area of meta- 

 notum large, aciculated,, obliquely narrowed towards the 

 apex ; areola nearly as long as wide, the sides at the base 

 obliquely narrowed, its apex slightly roundly turned in- 

 wardly ; posterior median area smooth, of uniform width 

 and rounded at the base ; the other arese closely punctured, 

 opaque ; the spiracular and the tooth-bearing area? more 

 strongly, irregularly, and not so closely striated. Propleura? 

 above closely punctured, the apex broadly, in the middle 

 longitudinally striated ; the base with a broad yellow band, 

 broader than the upper one on the pronotum ; mesopleurje 

 closely punctured, the middle-behind coarsely aciculated, the

 aciculated. Gastrocceli shallow, striated; the base rufous 

 striated. 



Alyathia robusta, sp. n. 



Is very similar in form and coloration to A. maculiceps ; 

 may be known from it by the yellow scutellum, by the 

 strongly striated front and vertex, by the areola being dis- 

 tinctly defined and the posterior median area not at all, 

 and by the apex of the hind tibiae and the metatarsus being 

 black.

 sternum, the apices of the first to fourth abdominal segments, 

 and the apical entirely, yellow. Four front legs fulvous,
