• 



cylindrical style, at the tip of which there is a minute bristle. Proboscis 

 short, thick, )btuse; palpi strongly clubbed, densely hairy. Thorax 

 large, broad, only gently convex above, thickly pilose, as in Dasyllis 

 Abdomen short, not twice the length of the thorax, very broad, depressed, 

 gently convex above, broadest at the base, the sides thence gently con- 

 vergent to the tip of seventh segment, which is very broad, the abdomen 

 thus appearing nearly truncate. . Legs short, stout, the front and especially 

 the middle femora thickened, the hind pair only a little elongated, less 

 thickened, cylindrical, of nearly equal thickness throughout (a very little 

 thicker on the proximal half), not clubbed as in DasylUs; hind tibiae 

 thickened and arcuate. Pulvilli small, narrow. Anterior cross-vein of 

 wings a little before the base of the fourth posterior cell and very near 

 the base of the discal cell ; the first posterior cell hence very long, very 

 narrow and closed a little before the tip. Anterior branch of the third 

 vein strongly curved forward, so as to meet the costa only a little beyond 

 the tip of the first vein. Fourth posterior cell closed a little before 

 the border ; anal cell acute, closed a considerable distance before the border. 

 The type of HypereckUi is Laphria xylocopiformis Walker, (List, etc., 

 ii, 385) from British India, and so far as I am aware but two other 

 species are known, viz : H. (^Laphria) robusta (Wied.) v. d. Wulp, whose 

 habitat is unknown, and H. /era v. d. Wulp, from Borneo.

9. — Very large, robust, black, densely clothed with black and yellow hair. 

 Hair of the face long, dense, brownish black ; on the first two joints of- the anten-

 the hair of the occiput dense, but not very long, together with that of the palpi 

 deep black. Dorsum of thorax with thick, light yellow pile, longer and more 

 abundant on the posterior part and on the scutellum. Pile of pleurae black : in 

 front of the halteres a very conspicuous and dense tuft of long yellow pile. Abdo- 

 men thickly clothed with erect, rather short blai-k pile; longer, bushy, and yellow 

 on the sides of the second segment just behind the halteres. Legs with black pile ; 

 on the front, hind, and more especially the middle coxae, the middle femora behind 

 and the hind femora in front, longer and yellow. Tibiae and tarsi reddi.sli black. 

 Wings nearly h valine, with a strong yellowish tinge in front. Length 22 mm.;
