not much smaller than those in the rows, so that the discal rows from some direc- 

 tions appear to consist of double the usual number. At a glance it looks close to 

 D. labial lis. but the prothorax is non-strigose throughout. The abdominal fovea is 

 unusually large, and is nut margined with hairs as on the females of many species. 



DITROPIDUS STRIATIPENNIS sp. nov. 



9 Metallic purple, elytra dark and metallic green, legs coppery or coppery- 

 purple, under-surface darker, labrum and basal half of antennae (the club 

 infuscated) reddish. Head, under-surface, and legs with comparatively long, 

 white pubescence. 



Head with dense but partially concealed punctures ; median line distinct. 

 Eyes moderatel}' distant. Prutliora.v at ape.x about as wide as the median length, 

 sides strongly rounded ; with dense and sharply defined but not very large punc- 

 tures in middle, becoming crowded and larger, but not confluent on sides. Elytra 

 witii sides gently rounded and narrowed posteriorly; with rows of fairly large 

 punctures, nearly all set in deep striae ; interstices impunctate or almost so. 

 Abdomen with a large, round, deep, apical fovea. Leys rather short. Length, 

 3-3 -25 mm. 



Hab. Queensland: (jood and Thursday Islands (G. E. Bryant). Type, L 

 10902. 



In size and outlines somewhat like /'. insiiUiris. and with prothoracic punc- 

 tures about the same size, but elytral sculpture very different, eyes larger and 

 closer together than in the female of that species, and under-surface more densely 

 clothed. I know of no really close ally. The prothoracic punctures frequently 

 ha\e a coppery glitter, as also have many on the elytra ; the elytra from some 

 directions appear entirely purplish : almost all their striae are deep, so that the 

 interstices at the summit of the apical slope are all separately convex, the only 

 series of punctures that are not in distinct striae are the two short ones on each 

 side of the suture. The distance lietween the eyes is about equal to the length of 

 the tliree apical joints of the club. 



DITROPIDUS VENTRALIS sp. nov. 



d Black, upper-surface cojjpery-bronze. six basal joints of antennae, 

 except upper-surface of first, reddish. Under-surface, pygidium, and legs with 

 sparse, whitish pubescence. 



Head with fairly dense punctures at base. Eyes large and almost touching. 

 Prothora.v at base decidedly less than twice the median length, sides strongly 

 rounded: with \ery minute (scarcely \-isible I punctures, except for a few large
