276 GUY A. K. MARSHALL. 



larger and more numerous than on the rest of the elytra, forming a large thin apical 

 patch ; a small spot of similar scales before the middle on interval 6 ; the lower 

 surface with the yellowish scales rather more numerous than above and mingled 

 with larger white scales that are bifid at the apex. 



Head with coarse confluent punctation, without a fovea on the forehead, the supra- 

 ocular furrow immediately adjoining the margin of the eye. Rostrum a trifle shorter 

 than the prothorax, with large, longitudinally confluent punctures and finely 

 tricarinate, the median carina being slightly higher, the lateral sulcus deep. Antennae 

 with the two basal joints of the funicle subequal, joints 3 and i about as long as 

 broad, 5-7 transverse. Prothorax as long as broad, the sides subparallel from the 

 base to the middle, thence roundly narrowed, and constricted at the apex ; 

 base shallowly bisinuate, the dorsal apical margin slightly arcuate, and the post- 

 ocular lobes feeble ; upper surface uneven, irregularly and unevenly granulate in 

 the middle, some of the granules coalescing to form larger elevations, and with a short 

 prominent carina in the middle of the central line ; the apical area with shallow 

 confluent punctures and scattered irregular granules ; the sides confluently reticulate, 

 the ridges between the foveae bearing small setigerous granules. Scutellum as long 

 as broad, strongly convex, with shallow confluent punctures and thinly pubescent. 

 Elytra broadest at the roundly rectangular shoulders and thence very gradually 

 narrowed to beyond the middle, with a very prominent posterior callus and the 

 apices separately pointed ; the disk with slightly irregular rows of large subquadrate 

 foveae as far as the declivity, where these are replaced by shallowly punctate sulci ; 

 the intervals uneven and irregularly granulate, interval 3 having an elongate granular 

 elevation near the base and a less conspicuous one about the middle. Sternum 

 finely coriaceous, the metasternum laterally with large, moderately close, shallow 

 punctures with raised edges, the punctures in the middle small and scattered, and a 

 longitudinal lance-shaped smooth area in the middle of the base. 



Length, 7J-9 mm. ; breadth, 3|-4J mm.

Very like a small D. (Hylobius) clathratus, Pasc. ; but in that species the rostrum 

 is 7-carinate and the central carina is not more raised than the others ; the forehead 

 bears a deep fovea ; the prothorax is closely set with regular rounded tubercles and 

 the post-ocular lobes are strongly developed ; the scutellum is flat ; and interval 

 3 of the elytra is regularly costate and without granular elevations. 



The adults of this species were also observed to be puncturing apple fruits. 



Subfamily Alcidlnae. 

 Alcides mali, sp. nov. (PI. xvii, fig. 3). 



$. Colour shiny dark reddish-brown ; the head, rostrum, apices of the femora 

 and all the tarsi black ; the elytra with the following slightly paler markings : a 

 narrow transverse band across the top of the declivity, a similar oblique band from 

 behind the shoulder to the middle of the suture, and an indistinct apical patch, all 

 these markings with a thin covering of pale plumose scales ; the lower surface reddish 

 brown, with the presternum, mesosternum and coxae blackish. 



Head with coarse confluent punctation and an impunctate curved furrow at a 

 little distance from the hind margin of the eye, the forehead flattened. Rostrum ( $)
