minatiug uear apex in small elongate tubercles, the 2ncl widely interrupted in 

 middle. Ditmensions : 7i x 2 mm. 



ifab. —Dorrigo, N.S. Wales. (Mr. A. E. Stephen). 



I am indebted to my friend Mr. Stephen for this addition to an interesting 

 group. It is mure nearly allied to E. cra-fsicornis Pase. than to E. lunatus Pasc. 

 --both of which I have from Tasmania, as well as two examples of the fonner 

 from Mount Wilson (Blue Mountains) — but it is quite distinct from both in 

 the form of antennae and prothorax, besides being larger. The specimen had 

 been kept in a cyanide bottle so that it had little chance of retaining any pale 

 coloured fascicles, if any existed. Type in Coll. Carter. 



Platydejia limbatum, n. sp. 



Oval, convex; whole surface, above and below, black suffused with red, 

 nitid; elytra with a pale lateral band, antennae and leg's red. 



Head and prothorax thickly and rather coarsely punctate, head unanned; 

 antennae with apical seven joints enlarged. 



Prothorax truncate at apex, base bisinuate, trout corners widely rounded, 

 liind angles rectangulai-, sides nearly straight, with narrow horizontal margin, 

 deeply bifoveate at base, disc without a sign of medial line or channel. 



Scutellum triangular, punctate. Elytra ovate, moderately convex, of same 

 width as prothorax at base, gi-eatest width behind middle, striate-punctate, the 

 seriate punctures round and regular, intervals flat and very iinely punctate. 

 Underside minutely punctate; leg-s slender. Dimensions: 3 x IJ (vix) mm. 



Hab. — Murray River, South Australia. (Mr. A. H. Elston). 



Three examples courteously sent by the discoverer can only be confused — 

 so far as colour goes — with P. linmcella Pasc. and its close ally P. abdominale 

 Geb. ; but the species is at once separated from both by much smaller size, less 

 convex form, unarmed liead of <?, more slender antennae, differently shaped 

 thorax and flat elytral intervals. It is the smallest of the Australian species 

 and in foi-m like P. oietoriae Blackb. The red colour is most prominent on the 

 head and pronotum, on the elytra showing only at the margins and shoulders. 

 Types in Coll. Carter. 



I have lately received from Mr. G. F. Hill of the Tropical Institute of 

 Medicine, Townsville, several examples of what I take to be P. deplanatum 

 Champ.; also an example of P. aries Pasc. without the usual red markings at 

 the apex of elytra. 



PlaTYCILIBE TRICLAVATUM, n. SJJ. 



Shortly ovate; head, prothorax and underside pale red, antennae and tarsi 

 testaceous. 



Head and pronotum distinctly, not closely punctate, antennae short, with 

 the last three joints enlarged into a club. 



Prothorax convex, slightly produced in middle at apex, truncate at base, 

 sides nearly straight and narrowing to apex; all angles subreetangidar ; lateral 

 border narrowly horizontal, disc without medial channel or foveae, with a row 

 of larger lateral punctures besides the somewhat sparse and deep punctures on 

 disc. 



Scutellum arcuate-triangular, witli about six large punctures. 



Elytra of same width as prothorax at base, oval; seriate-punctate, with 

 tome large confused punctures near base in humeral region; the surface other-
