NEW SPECIES OE CURCULIONIUAE. 167 



half scarcely smaller than those at the base, with a shallow elongate median fovea 

 above the insertion of the antennae, and with a smooth median line on the apical 

 half only ; the sides clothed in the basal half with spatulatc scales that are fringed 

 at the apex ; (^ without any projection on the submentum. Antennae with joint 1 

 of the funicle about as long as the next three together, 4-6 subequal and as long as 

 broad, 7 densely squamose and a little longer than its apical width. Prothorax 

 nearly twice as broad as long, broadest at the base, the sides gently rounded and 

 markedly constricted near the apex, the dorsum closely set with low convex 

 granules, except the apical area, which is strongly punctate ; each granule bearing 

 a forwardly-directed seta (usually bifid) on its anterior edge, and the sides of the 

 apical area with numerous fan-shaped plumose scales, a few of which occur also on 

 the median basal lobe. Scittelhim small, transverse, tilted forwards, and not at all 

 enclosed in front by the elytra. Elytra broadly heart-shaped, scarcely longer than 

 the width at the shoulders, which are obtusely prominent ; the striae containing 

 round, deep punctures, which are for the most part separated by more than their 

 own width and become much shallower behind ; the intervals broader than the 

 striae, convex, transversely rugose, but not granulate, and sparsely set with small 

 setiform scales, which are often bifid, trifid or quadrifid. Lci^s comparatively short 

 and stout, and thinly clothed with narrow, cleft scales ; the hind legs unusually 

 short, so that when outstretched the femur reaches only the apex of ventrite 6 (4th 

 visible), and the tibia exceeds the elytra only by its apical third ; the tooth on the 

 front femora of very unusual shape (fig. 3), being in the form of an irregularly trifid

lamina, that on the mid-femora truncate at its apex and with two minute teeth on its 

 external edge, that on the hind femora very small and simple ; the front tibiae with 

 a stout median tooth on the inner edge and a subapical one of almost equal size, 

 the mid-tibiae with a subapical tooth but no median one, and the hind tibiae simple. 

 Venter clothed with cleft scales, which only partly conceal the integument; ventrite 7 

 (last visible) with a large rounded median impression in the ^. 



Length, 6 -5-7 -2 mm. ; breadth, 4 -25-4 -8 mm. 



United Provinces : Dehra Dun, bred from seeds of Dipterocarpus, vii.1911. 



Described from four specimens. 



The rhomboidal outline and general structure make this species look like a very 

 small A. crassus, Pasc, from the Andamans ; but the latter differs, inter alia, in 

 having a median internal tooth on all the tibiae, the intervals on the elytra are quite 

 smooth and sparsely punctate, the tooth on the fore femora is triangular with a 

 denticulate outer edge, and the (^ has two tufts of setae on ventrite 7. 



There are several closely ahied, and apparently undescribed, species in Malaya, 

 from all of which A. dipterocarpi may be distinguished by the peculiar form of the 

 tooth on the front femora (fig. 3).
