398 DESCKIPTIOXS OF XEW SPECIES OF AUSTRALIAN COLEOPTERA, 



Strongly rounded; punctures very minute. Elytra short, sides beyond middle 

 stronjilv rounded. Length, 1.2 — 1.3 mm. 



2.— Differs in the usual particulars of eyes, legs and abdomen. 



//a^._-\Vestei-n Australia: Geraldton and Swan River (A. M. Lea). Dirk 

 Hart og Island (Dr. Michaelsen). 



In general appearance very near punctulum, but slightly narrower and elytra 

 shagreened, on that species the head and prothorax. but not the elytra, are shag- 

 reened. the shagreening is not so pronounced as that of the head and prothorax, 

 but is (]uite distinct ; from some directions vague lines reiiresenting series of punc- 

 tures may be seen on the discal parts, and even the lateral striae are very feeble, 

 on several specimens only the marginal stria on each side is present: an incon- 

 spicuous depression traverses the base of the seutellar lobe; the median line of 

 the metasternum is diliited at the base so as to form a fairly large but shallow 

 fovea . 



DlTROPIDUS TRAXQUILLUS, n . sp . 



d".— Black, labium, basal half of antennae (club infuscated) palpi and parts 

 of legs more or less reddish or flavous. Glabrous. 



Head evenly convex; with small, but rather sharp punctures; median line 

 scarcely traceable. Eyes rather widely separated. Prothorax more than twice 

 as wide as the median length, sides strongly rounded; with rather dense and small, 

 ))ut sharply defined punctures. Elytra subquadrate; with series of small punc- 

 tures, on the sides set in deep striae. Length (c?, ?), 1.75 — 2 mm. 



9. — Differs in the usual particulars of eyes, legs and abdomen.. 



Ilah.—'tiew South Wales: Sydney and Como (A. M. Lea). 



Slightly larger and more compact tlian D. ragans, and elytral jninctures almost 

 the same, but prothoracic punctures slightly smaller, and all parts of the upper 

 surface shining and nowhere shagreened or opaque ; the prothoracic punctures are 

 much smaller than on D. rotuncliformi.-i, and the legs are paler. There are dense 

 and sharply defiiied punctures on almost the whole of the under surface. The 

 knees, tarsi, and hind femora are usually d.Trker than the rest of the legs, some- 

 times the hind femora are only partly dark, occasionally the tibiae are scarcely 

 paler than the tarsi. 



DiTROPIDUS RUFISr.\NUS, H.Sp. 



d". — Black; clypeus, labrum, most of inter-ocular space, l)asal half of an- 

 tennae (the club infuscated) palpi, front legs (knees infuscated), middle and hind 

 tarsi, more or less red. Under surface and legs with \-erv sparse pubescence. 



Head subopaque; with small and fairly dense punctures; median line liglitly 

 impressed. Eyes rather widely separated, rrothora.r about twice as wide a.s the 

 median length; with very small but sharply defined punctures. Elytra briefly 

 suboblong, with rows of rather large punctures, becoming much smaller posteriorly, 

 and set in deep striae on the sides. Fmnl h'l/s slightly longer than hind ones. 

 Length (c?, $), 2—2.2.5 mm. 



$. — Differs in being more rol)ust, eyes more apart, inter-ocular space, clypeus 

 and front femora black, seriate punctures of -elytra smaller, front legs no longer 

 than hind ones, and abdomen larger, more conve.x, and with a large, ajiical fovea. 



Wa!*.— South Australia: Mount Lofty (A. M. Lea). 



In some respects fairly close to the description of D. farialif, but middle (ibiae 

 dark, on the head of the female only the labrum is pale, the sides of the metas-
