species as other tlian aberrant members of that genus. The 

 rostrum, when seen from the side, appears to be very thin 

 (much thinner than in Eristua setosus or bicolor), but from 

 in front appears to be very wide. Four specimens of 

 eiicalyiJti have their mandibles unclenched, and these are 

 seen to be acutely bidentate at the apex. 



Only one specimen of the genus was sent by Mr. Bryant, 

 but I have associated with it another species of which there 

 are several specimens under examination, and another also 

 represented by a single specimen. Tliey may be tabulated 

 as follows : — 



Eyes close together and elytra glabrous eucalypti. 



Eyes moderately separated and elytra clothed. 



Legs uniformh' pale Jlavipes. 



Femora much darker than tibise and tarsi .^ . . sobrinus, 



Eristinus eucalypti, sp. n. 



^ . Black ; rostrum, antennae, and legs fluvous. With 

 some whitish hairs on head, piothorax (the disc glabrous), 

 and under surface ; dense only on sides of mcsu- and of 

 metasternum. 



Head with a few distinct punctures near eyes. Eyes large, 

 close together, and coarsely facetted. Rostrum Avide, thin, 

 and almost parallel-sided, about twice as long as wide ; with 

 distinct but not very dense punctures. Scape short, some- 

 what curved, much shorter than funicle ; first joint of the 

 latter stout and moderately long. Prothorax moderately 

 transverse, sides evenly rounded, base lightly bisiuuate and 

 not much wider than apex; with numerous punctures of 

 rather small size, clearly defined on disc, but obscured on 

 sides. Scutellum small but distinct. Elytra much wider 

 than protliorax and about thrice as long, shoulders feebly 

 rouuded, sides slightly dilated to beyond the middle, and 

 then widely rouuded to apex; with rows of punctures, fairly 

 large at the base, but becoming much smaller posteriorly. 

 Abdomen with small punctures, two basal segmenis rather 

 large, in male flattened across middle, in female convex, 

 second, third, and fourth directed slightly backwards at sides. 

 Legs rather short and stout; femora edentate. 



Length 1^-2 mm.

 Tambourine (C J. Wild). 



The elytra are quite glabrous; their punctures are in 

 regular rows, but not striae, although in places traces of 

 same may be noticed.
