140 ON THE SCARITID^E OF NEW HOLLAND, 



species. But the thorax is the most remarkable feature of the 

 insect, for it is broad, rectangular, and truncated, and there is no 

 curve behind, as is the case in all the other groups into which 

 the genus may be subdivided. 



In addition to the above new species, Mr. Waterhouse's collection 

 contains specimens of Carenutn tinctilatum Newm., C. laevipenne 

 mihi., G. loculosum Newm., and G. tuberculatum mihi., and a 

 species of Scarites, which seems to be identical with the species 

 described by me in my former Paper, as S. Damastes. 



I take this opportunity of giving the descriptions of ten new 

 species of Garenum, six of them in the collection of W. S. MacLeay, 

 Esq., of Elizabeth Bay, and the remainder in the Australian 

 Museum. They all belong to the tridentate section, with the 

 exception of C. scituhim, affine, and pundulatum, which have the 

 fore tibise bidentate. 



10. — Carenum deauratum. 



Cupreum subnitidum cyaneo-marginatum subtus chalybeum, 



thorace transverse antice truncato postice rotundato 



basi late marginato, elytris subtiliter seriatim punctatis 



foveis quinque seriatim impressis, tibiis anticis extus 



tridentatis. 



Long. 6| lin., lat. 2| lin. 



The upper surface of this insect is of a rather dull coppery 



red, margined wdth blue ; the under surface is a brilliant steel 



blue. The head is rather flat, and is marked near the hinder 



margin with a transverse groove, from which the two facial grooves 



take their rise ; these are deep and nearly parallel for some 



distance, when they turn outwards towards the anterior angles of 



the head. The thorax is broader than long, almost truncated 



in front, rounded behind, and broadly margined at the base ; the 



medial line is deeply marked and the anterior margin is a 



little corrugated. The elytra have the humeral angles large and 



prominent, and are rounded behind. On each elytron there are 



six rows of minute punctures, and one row of round foveae ; 



in the specimen before me, there are five of these fovejB on the 



right elytron and four on the left. The fore tibife are tridentate 



externally, the upper tooth being much smaller than the other two. 



This beautiful and unique insect was sent lately from the
