210 Arthur M. Lea : 



finely serrated, but otherwise parallel-sided to near apex ; with 

 close, regular rows of large punctures. Under surface densely 

 punctate. Legs rather short ; femora stout. Length 3^ — 3 2-3 

 mm. 



Hab. — Victoria: Birchip, in nests of Crematogaster laeviceps 

 (J. C. Goudie) ; N.S. Wales : Clarence River (G. Compere), 

 Forest Reefs, under a log close to an ants' nest (A. M. Lea). 



Several s^^ecies of the genus are known to have short setae, 

 but on this species the clothing is decidedly long. The teeth on 

 each side of the prothorax vary in number from four to six, 

 exclusive of those (which are usually much smaller) on the pro- 

 duced front angles. 



Kershaivia rugiceps. Lea. 



Occurs in nests of Iridomyrmex nitidus. 



Both Messrs. Goudie and Davey have sent a bright red larva 

 as belonging to this species. It is of an almost blood-red colour, 

 and subopaque, with the head shining and dark brown, except 

 the muzzle, which is somewhat reddish ; on the first thoracic 

 segment there is an infuscate shining M ; on each of the two 

 following segments there are two rounded, infuscate, shining 

 spots. Tlie apical segment on its upper surface is shining, the 

 colour of the head, and with two long pale acute processes 

 curved at their apices. Scattered all over the upper surface 

 and sides are some long yellowish hairs ; the under surface 

 has much shorter but similarly coloured hairs. The length of a 

 full-grown larva is 6 mm. 



Bothrideres tibialis, Blackb. 



Mr. Davey informs me that he has taken numerous specimens 

 of this species under the bark of Eucalyptus trees, in the nests 

 of Colobopsis gasseri. They were probably there by accident, 

 however. 



Tretothoracidae, n. family. 



Antennae teu-juinted, non-clavate. Mentum wide, entirely 

 concealing mouth parts. Metaslernum elongate. Four front 

 tarsi five-jointed, the others four-jointed, subapical joint of each 

 not bilobed.
