104 Mr. David tSharp on the 



DiALLOBirs, n. gen. 



Generis Phyllobii proxime affinis. Rostrum apice lato, ptery- 

 giatum, angulis anterioribus acutis, breviter recurvatis. 



This genus has the facies of the densely scaled specips 

 of Pliyllohius — P. pomonpe — e.g., but the peculiar 

 dilatation of the apical part of the rostrum, by which the 

 scrobes are made anterior and entirely exposed in front, 

 is diagnostic. The structure of the parts of the mouth 

 appears to be much the same as that of Phyllohins, the 

 mentum is, however, rather less slender, so that the 

 maxilloB are not exposed ; the minute labial palpi are, 

 however, seated on the front of the mentum and quite free. 

 There is no trace of either vibrissse or ocular lobes. 



The species of this genus seem to be of great rarity. 



1. DlaUohius iriornatus, n. sp. 



Dense argillaceo-squaniosus, vix variegatu?, antennis rufia, 

 femoribus dentatis. Long. 4^-0 mm. 



Antenna rather stout, scape scarcely surpassing the front 

 margin of the thorax. Chib, rather short, oval, solid, but with the 

 sutures visible. Rostrum very densely and evenly squamose, eyes 

 rather large, scarcely prominent, separated by a long distance from 

 the thorax, this latter short, slightly curved at the sides, and 

 evidently narrower in front than at the base. Elytra very densely 

 squamose, without any pubescence, the series of fine punctures 

 very distinct notwithstanding the sqiiamosity. Under surface also 

 densely squamose, but the clothing is on the abdomen less perfect, 

 on the apical segment there being merely hairs, or rather setae, 

 instead of scales. Legs rather stout, all the femora with a 

 definite tooth. 



Two specimens found by the late Mr. Fryer. The 

 smaller specimen is probably the male. 



2. DlaUohius mundus, n. sp. 

 Dense squamosus, pallidu.^, subviridis, antennis rufis; femoribus 

 iutermediis et posterioribus fortiter dentatis. Long, bh mm. 



Similar in appearance to the European P. pomonsf 

 and allies ; extremely densely covered with adpressed 

 scales, of a pale colour, with a very slight tinge of green, 

 and here and there slightly iridescent or metallic. In
