and species of Pselaphidcc and ^Scjjdmcenid^B. 511 



Mas, pedlbus intermediis tumidis; metasterno pro- 

 mmnlo medio ciliato; abdomine segmento basali ventrali 

 medio lortiter transversim constricto-depresso, foveoldque 

 parva ; pygidio apice impresso. ^ 



The short aiiteiina3 are a little longer than the short 

 head ; thej are slender at the base, much thickened in the 

 middle, the truncate extremity not quite so broad as the 

 middle. Ihe pimctuation of the front parts of the body 

 IS coarse and close, coarser in the female than in the male • 

 the thorax is small, about as long as broad, the sides 

 straight m the female, very slightly narrowed behind in 

 the male. The legs are short. The intermediate legs in 

 the male are enormously swollen, the thighs being short 

 and extremely thick, their basal portion produced down- 

 wards ; the tibitB broad and extremely short, and capable 

 of being accurately adapted to the under surface of the 

 femur. 



West Australia : five specimens, collected by Mr. Du 

 Boulay. 



Articerus Pascoeus, n. sp. Flavo-ferrugineus, antice 

 fortiter punctatus, elytris evidenter setulosis, antennis 

 brevibus, capite paulo longioribus, intus extusque simila- 

 riter rotundatis ; prothorace parvo, quadrato, dorso foveo- 

 lato. Long. corp. \^ mm. 



Mas, tibiis anterioribus apice calcari armatis, tibiis 

 intermediis extus infi'a medium angulatis, intus apice 

 unco acuminato ; posterioribus apicera versus leviter dila- 

 tatis ; abdomine apice fortiter deflexo ; metasterno medio 

 apice penicillo parvo. 



The short antennas have a slender basal portion, and 

 beyond this are dilated into an oval form, but with the 

 extremity truncate; the base of this oval is thin and 

 laminate, and its surface is impressed. The head is 

 short, being scarcely longer than the thorax, but the eyes 

 are placed at a little distance from its hind part. The 

 thorax is small and narrow, and about only half as broad 

 as the elytra, quite as long as broad. The elytra arc 

 much narrower at the shoulders than at the apex. 



Found in West Australia by Du Boulay. 



In the male of this species the calcar at the extremity 

 of the front tibi* is easily overlooked, as it is placed behind 



the tarsus. ^ -r> -p
