362 DESCRIPTIONS OF NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



EROTYLIDAE. 



Episcaphula tetrasticta^ n. sp. 



MetaDic purple; elytra with four flavous spots, under surface except sides of 

 presternum, palpi and parts of leg-s reddisb-flavous, rest of legs and antennae 

 blackish, but in places obscurely diluted with red. 



Head with distinct but not very large or dense punctures, becoming smaller 

 and denser on elyjieus. Third joint of antennae more than twice the length of 

 fourth. Prothorax more than twice as wide as long, sides diminishing in width 

 from base, front angles produced but not very acute; punctures somewhat smaller 

 and sparser than on head; submarginal line deep. Elytra slightly dilated- from 

 shoulders to about basal fourth, and then narrowed to apex; with rows of dis- 

 tinct, but not very large punctures, the interspaces with mucli smaller ones. 

 Abdomen with coxal lines traceable to apex of basal segment, but rather faint 

 posteriorly. Length, 5.75-6 mm. 



Hab. — Queensland: Cairns (E. Allen). 



A smaU, rather wide species, allied to E. inclusa, but smaller and elytra 

 with four isolated, pale spots, placed a-s in the angles of a square : two basal and 

 two median, each of the latter occupies the space between about six lines of punc- 

 tures, each of the former between about four. 



Thallis basipennis, n. sp. 



Chocolate-brown ; elytra, under surface, leg's and palpi paler. Densely 

 clothed with pale pubescence, becoming conspicuously golden on base of elytra. 



Head with crowded punctures of moderate size. Antennae with third joint 

 about once and one-half the length of second; club not very large. Apical joint 

 of each palpus scarcely larger than basal joint of antennae, and not securiform. 

 Prothorax about once and one-fourth as wide as long, apex widely truncated, 

 scarcely notched near each side, sides gently rounded, front angles scarcely pro- 

 duced, the hind ones acute; with crowded but not very large punctures, many 

 of which are slightly confluent longitudinally. Elytra no wider than prothorax, 

 and scarcely twice its length; with regular rows of punctures in distinct striae, 

 interstices gently convex, separately narrowly elevated at base, with dense punc- 

 tures. Prosternum witii intercoxal process narrow, its hind end truncated. Coxal 

 lines of abdomen faintly traceable to apex of basal segment. Length, 4.5-5 mm. 



Hab. — North Western Australia: Upper Ord River (R. Helms). 



The elj'tra appear to be fasciate at base, the fascia interrupted at suture, 

 but this appearance is really due to the Inight golden pubescence there; at the 

 base they are very narrowly elevated, and the scutellum is elevated in the same 

 line. Owing to the convexity of the pronotum the impressed line on each side 

 is only visible at base and apex from directly above. One specimen has the 

 elytra no paler than the prothorax, and the basal fascia of pubescence hardly 

 golden. The species may be eventually transferred to a new genus, as the base 

 of its elytra and apical joint of each palpus are aberrant. 



EuxESTUS ventralis, n. sp. 



Black ; bead, apex of elytra, and epipleurae obscurely reddish, legs, an- 

 tennae and palpi eastaneo-flavous. Glabrous. 



Head with dense and small but sharply defined inmctures, a small fovea on 

 each side of clypeus. Antennae short, ba.sal joint large, club slightly wider than
