ridge terminating posteriorly in an acute tooth directed obliquely 

 backwards, between the ridges and the eyes there is on either side a 

 rather deep longitudinal excavation, rounded in front and bordered 

 posteriorly by another shorter tooth directed obliquely backwards, 

 both median and lateral excavations filled with pale pubescence; with 

 numerous moderately defined punctures; antennae of moderate length, 

 club of three joints, apical joint pointed. Prothorax broader than 

 head, sides much widened on their apical halves and recurved into 

 the form of a strong spine which is itself toothed, and which is 

 directed upwards, a little outwards and a little backwards. On either 

 side of prothorax is a v/ide, deep excavation, which forms a rather 

 sharp edge with the uppersurface, thus making the whole discal area 

 look like a raised shield; with puncturation as on head. Elytra a 

 little transverse, sutural striae deep, dorsal well marked to about 

 apical third; puncturation irregular, and not very distinct. Abdomen 

 at widest wider than elytra, second and third segments with a very 

 short black carina on either side, placed nearer the outer margin than 

 the centre. Legs unarmed. 



Length, 2.5 mm. 



Habitat. — Victoria: Ringwood, Beaconsfield, Healesville, (F. E. 

 Wilson). 



Type in author's collection. 



This insect is undoubtedly congeneric with C. scitlvticeps, Lea2, 

 although its second abdominal segment is not tricarinate. The armed 

 prothorax and different abdominal carination readily distinguishes it 

 from that species. The antennal club differs greatly from Mr. Lea's 

 species, the ninth and tenth joints being much less markedly trans- 

 verse, and the eleventh joint being pointed instead of widely rounded. 

 Owing to the rather dense pubescence it is somewhat difficult to see 

 the sculpture of the head and prothorax. All my specimens were 

 taken in damp moss growing on the ground. 



SCHISTODACTYLUS AliMlPECTUS, n.Sp. 



S Castaneous, elytra and appendages paler; antennal joints 7-10 

 inclusive strongly infuscated; somewhat sparsely clothed with pale 

 decumbent pubescence. 



Head about as long as broad, lightly impressed between antennae, 

 with two somewhat indistinct inter-ocular foveae; with dense, very 

 clearly defined, punctures, becoming more sparse on disc near base; 

 antennae with joint 1 cylindric, longer than 2 and 3 combined, 2 

 broader and scarcely perceptibly longer than 3, 4, 5, 6 and 7 decreasing 

 in length, 8 wider and a little shorter than 7, 9 much wider than 

 8 and slightly longer, 10 wider and shorter than 9, 11 subovate, longer 

 than 9 and 10 combined, and forming with them a three jointed club. 

 Prothorax about as long as wide, widest at about apical third, sides 

 strongly rounded to their widest part, thence almost straight to base 

 which is subequal in width to apex; puncturation as on head. Elytra
