of hairs, similar to those on the sterna, overlapping the base of 

 the scutellum. The flabellum at first glance appears to be 

 but five- jointed, as the produced part of its basal joint is 

 much shorter than that of the following one, and from some 

 directions is concealed. To the naked eye the elytra appear 

 to have vague remnants of discal costae, but these disappear 

 under a lens. One of the specimens before me bears Black- 

 burn's name label " Rhopaea hirtuosa, Blackb." and in fact 

 it strikingly resembles that species, but it belongs to a different 

 section of the genus, as the flabellum, including the first short 

 one, consists of but six joints, instead of seven. Of the males 

 of the group AAA, it is distinguished from verrecmxi by the 

 shorter third joint of antennae, with the produced part of the 

 fifth longer and more acute, the apical joint of the palpi is 

 also much narrower; mussoni has the ramus of the fifth joint 

 considerably longer and wider, and the palpi different; rugu- 

 Josa has the upper-surface almost glabrous : from the descrip- 

 tion of dub items it differs by the sides of the prothorax not 

 being angular in the middle ; by the table the third joint not 

 "considerably longer than wide" should distinguish it from 

 con sail guinea. 



Paralepidiota cavifrons, n. sp. 

 PL xxvi., fig. 50. 



d" . Pale flavo-castaneous, elytra and antennae paler, 

 tibial teeth blackish. Head, prothorax, and scutellum with 

 snowy-white, rounded or elliptic, depressed scales, becoming 

 thinner and more or less setiform on elytra, abdomen, and 

 parts of legs ; sterna and parts of legs with dense, whitish hair. 



Head strongly convex, and with rather large and dense 

 punctures, becoming smaller and sparser in middle of base. 

 Clypeus bilobed, margins strongly elevated. Antennae ten-, 

 flabellum seven- jointed, first joint of the latter about one-fifth 

 shorter than the others. Apical joint of maxillary palpi wide, 

 with a wide shallow median depression. Prothorax strongly 

 convex, sides widely rounded and finely serrated, all angles 

 obtuse; punctures sparser than on head, and much sparser 

 about middle. Elytra slightly dilated to beyond the middle, 

 apices obliquely truncated; punctures fairly dense and moder- 

 ately large, becoming smaller and sparser in parts, discal 

 costae lightly defined. Pi/c/idium rather strongly margined, 

 apex feebly bilobed ; punctures rather numerous. Front 

 tibiae strongly tridentate, hind tibiae with unequal spurs at 

 apex, the larger one dilated to beyond the middle, and then 

 narrowed to apex. Length, 20-21 mm.
