Head with rather dense and sharply defined punctures; 

 median line slightly impressed. Prothorax about twice as 

 wide as the median length, sides strongly rounded; punctures 

 dense and small. Elytra moderately long, sides gently 

 rounded ; punctures slightly larger and somewhat sparser 

 than on prothorax; striae fairly distinct on sides, absent, or 

 almost so, elsewhere. Abdomen with a large apical fovea. 

 Length, 375-4 mm.

 Type, I. 10954. 



An oblong-elliptic species, with general outlines as in 

 tifjnnui<, signifer, simplex, and similar species, and varying 

 considerably in its colours. By the table given by Chapuis 

 it could only be referred to Elaphodes or Ditropidus, and as 

 it is clothed all over and the joints of the club are rather 

 elongate, I prefer to refer it to the former genus; in general 

 appearance it strikingly resembles many small Coccinellidae, 

 especially of the genas Rhizohius. There are six females^ 

 before me, of these the type and another specimen have the 

 extreme base of prothorax, scutellum, and elytra (except tips) 

 black, all other parts (except that some of the antennal joints 

 are infuscated) being red ; two others differ in having a wide 

 median fascia (connected along the sides with the tips) on the 

 elytra also red (on the two first specimens the fascia is hardly 

 indicated, but in part may be traced from certain directions) ^ 

 the other two have the prothorax entirely black, and only the 

 extreme tips of the elytra red, with the sterna partly 

 infuscated. 



COENOBIUS. 



The species of this genus in general are close to 

 Ditropidus, but differ in having the antennal club composed 

 of six instead of five joints, and the scutellar lobe not notched; 

 the latter character, however, is not very satisfactory, as it 

 frequently happens that in the small dark species of 

 Ditropidus the notch is very indistinct. I have not referred 

 to Ditropidus, however, any species with the club six- join ted, 

 or to Coenohius any with it five- jointed. 



COENOBIUS LUCIDULUS, Chp. 



A male from Darnley Island appears to belong to this 

 species, but has the legs of a rather dingy flavous. Math the 

 four hind femora somewhat darker; two other males (from 

 Northern Queensland and Port Douglas) differ from it in 

 having the legs entirely dark. A female, from Cairns, has 

 also entirely dark legs, but differs from the males in being
