and the tips of the others are also more or less reddish. The median length of 

 the prothorax is slightly more than the apical width. 



DiTROPIDUS LATICOLLI.S, n.Sp. 



?. — Black; labiiiui, basal lialf of antennae (the club infuscated) and palpi rather 

 obscurely tlavous; elytra with sides and apex widely tiavous, elsewhere infuscated; 

 leg's in parts obscurely diluted with red. Under surface and legs slightly pubescent. 



Head shagreened and with dense, fine, aciculate punctures, more distinct on 

 clypeus than elsewhere. Eyes rather widely separated. Antennae short. Pro- 

 thorax more than twice as wide as the median length, apex scarcely half the width 

 of base; shagreened and with dense, tine, aciculate punctures, becoming crowded 

 in front angles. Elytra scarcely as long as wide, sides moderately rounded; with 

 rows of distinct but not very large punctures, becoming larger and set in deep 

 striae on the sides ; interstices with dense and very fine punctures, or feebly 

 shagi'eened. Abdomen with a large, round, deep, apical fovea. Length, 2.75^ 

 3 mm. 



Rah. — Queensland: Duaringa (G. Barnard). 



A curious round species of which I know no close ally. On two speci- 

 mens the elytra have the sides widely tlavous, from the base to and across the 

 apex (but there is a slight infuscation on the sides above the abdomen), thus 

 bounding on three sides a large, subc^uadrate, deeply infuscated patch; on a third 

 specimen the infuscation is extended so that the tlavous parts (which are consider- 

 ably reduced in intensity) are confined to the vicinity of the shoulders and apices; 

 on the third specimen the median line of the head is very distinct, on the others it 

 is feeble. The distance- between the eyes at their nearest is about eciual to the 

 length of the three basal joints of the antennae, but it would be less in the male. 

 The pronotum has a vague bronzy gloss, but it could hardly be regarded as me- 

 tallic; from some directions it appears to be very finely pubescent, but under a 

 compound power it is seen to be quite glabrous ; the hind angles from above ap- 

 pear to be quite sharply acute, but from the sides they are seen to be rectangular; 

 the notch of the scutellar lobe is very feeble. The intercoxal process of the pros- 

 ternum is almost twice as wide as long, truncated in front, and feebly incurved 

 behind . 



DiTROPIDUS IMPCXCTICOLLIS, n.sp. 



?. — Black; lalirum, basal half of antennae (the club infuscated), pa]];.i, ab- 

 domen, legs, and a variable amount of elytra tlavous. Under surface and legs 

 vei-y feebly pubescent. 



Head shagreened and subopaque; median line feeble. Eyes widely separated. 

 Prothorax about thrice as wide as the median length, sides stiiongly narrowed to 

 apex; impunctate. Elytra about one fifth longer than wide, sides moderately 

 rounded : with rows of rather small but distinct punctures, on the sides set in dis- 

 tinct striae. Abdomen with a large, round, deep, apical fovea. Length, 1.75 — 2 

 mm. 



Tlab. — Western Australia: Karridale (A. M. Lea). 



A minute species without punctures on tlie prothorax, even on the sides. 

 The hind end of the prosternal process is almost truncated, but as the scutellar 

 lobe is notched, the scutellum minute, and club five-jointed the species was re- 

 ferred to Ditropidiis without hesitation. Of the two specimens under examina-
