carina towards each side of upper surface, and rather longer 

 but less distinct than in preceding species ; under surface with 

 a feeble impression in middle of second segment, and a similar 

 one on third. Metasteriium strongly impressed along middle. 

 Legs long and thin ; front tibiae strongly curved and somewhat 

 thickened in middle, the middle pair moderately curved near 

 apex, the hind pair almost straight. Length 2 mm.

 nitidus (H. W. Davey). 



The head has a peculiar appearance, as of having a spine 

 over the base of each antenna, when viewed from the side, as 

 in formicinus, but it differs from that species in being smaller, 

 with cephalic foveae more, and the abdominal ones less, pro- 

 nounced and the clothing shorter and sparser. The size and 

 clothing are much as in macleayi, but that species has the 

 tenth joint of antennae very distinctly shorter than the ninth. 

 The palpi are much as in the preceding species, but the antennae 

 (especially the basal joint), ai)dominal impressions, clothing and 

 shape are different. 



Each elytron at the base has a strong impression, its inner 

 wall from some directions appearing carinated posteriorly, 

 but the impression terminates before the middle, and could 

 scarcely be regarded as a stria. The type has been described 

 as a male, as its ventral impressions, although faint, are quite 

 distinct. 



T ))iesi pliorus hrevicornis, n.sp. 



Dark reddish castaneous, elytra club and tarsi paler, palpi 

 still paler. With very short pale pubescence. 



Head transverse ; with two small inter-ocular foveae ; with 

 a deep impression between antennary ridges ; with a short 

 spine behind each eye on the side; densely and rather coarsely 

 punctate. Antennae rather short and stout, scarcely extending 

 to base of prothorax, first joint from above apparently slightly 

 shorter thaxa second, l)Ut really about twice as long, second to 

 eighth transverse, ninth considerably longer and wider, but 

 feebly transverse, tenth the width of but shorter than ninth, 

 eleventh briefly ovate. Prothorar strongly convex, slightly
