liv Airniuu ii. LEA. 387 



Var. a. Some specimens (from Sytlney, Maitlaml and Aimidale) differ in 

 being of a darker and less coppery-g-reen, and with the legs entirely dark; but I 

 can tind no structural differences from the tyi)ical foi'm. 



DiTROPIDUS PUNCTULDM Clip . 



This species ranges 1.25 — 1.5 mm. in lengfh. The eyes are rather widely 

 separated in the male, still more in the female. There was a ootype in tlie Black- 

 burn collection and otiiei' specimens before me are from Queensland { Hribie 

 Island), South Australia (Mount Lofty, Port Lincoln and Murray Bridge), and 

 Western Australia ( Swan River) . 



DiTHOPiDU.s co.vvExiuscuLus Clip, (formerly Elaphodes.) 



Two specimens, from Bowen, appear to belong to this species, described, with- 

 out the sex of the type being noted, originally as an Elaphodes. The antennae 

 of the male are lirokeii, but those of the female are slightly shorter and stouter 

 than in T). ctimuHs, referred by Chapius to Ditropidus. The male has a conspicu- 

 ous cross of white pubescence on the pronotum, on the female the cross is present 

 but less distinct ; the female has a conspicuous median fascia of white pulicscence 

 on the elytra, but on the male this is not di.stinct, owing to their clothing being 

 almost entirely white. In appearance the sjiecies is fairly close to cumrnis, l)ut 

 differs in having the jirothorax scarcely gibbons, not shagreened, its punctures 

 more sliari)ly defined and not at all elongate, and the elytral striae distinct only 

 near the sides. 



DiTROPIDl'S COJIAXS Chp. 



On this species there is usually, but not always, a distinct median fascia of 

 W'hite clothing on the elytra, the prothorax is gil)boHS in front, and at the middle 

 is either glabrous or very sparsely clotlie<l, allowing the dense punctures and finely 

 shagreened surface to be clearly seen . The distance between the eyes is about 

 equal to the length of the basal joint of the antennae in the male, considerably 

 more in the female; the length ranges 1.5 — 3 ram. The species occurs from 

 Dalby, in Queensland, to the Swan River, in Western Australia. 



DiTROPIDUS PUBICOLLIS Chp. 



Recorded by Chapius without exact locality ; specimens before me agreeing 

 with his description are from New Soutii Wales (Goulliurn, Tamworth and Wind- 

 sor) and Soutli Australia (Quorn and Lucindale) . 



DiTROPIDUS PUBKRULUS Clip. 



A specimen from Geraldton (Western Australia) possibly belongs to this 

 species; it is a male (the type was a female) and differs from the description in 

 being slightly smaller (2.25 mm.) and in having the parts flavous that were noted 

 by Chapius as ferruginous, except that the Joints of the club are infuscated at 

 their tips. 



DiTROPIDUS ilACULICOLLlS Clip. 



A s])ecimen from Brisbane (the type was from Sydney) agrees well with 

 the description of this species; its abdomen is more strongly convex than is usual 

 in males, and the tip of the jivgidium is not encroaching on the lower surface; but
