132 MISCELLANEA ENTOMOLOGICA, NO. IIL 



Carenum purpureo-marginatum, n. sp. 



Of broad sub-depressed form, black and sub-nitid with the 

 thorax and elytra margined with bluish violet. The head has the 

 frontal sulci almost parallel, and the clypeus thick and bi'oadly 

 and lightly emarginate. The thorax is transverse, slightly broader 

 than the head, and rounded at the base and posterior angles. 

 The elytra are broad and oval and faintly striate with two 

 strong punctures on each elytron as in C. Bonellii, a small cluster of 

 punctures on the base near the humeral angles and a close row of 

 them in the lateral margins. Legs very strong and much ciliated. 



Length, 11 lines. 



Hah. — Coonabarabran. 



Laccopterum lacunosum, n. sp. 



Like L. Spencei, but smaller ; the head as in that species ; the 

 thorax black bordered with bluish green, transverse, the posterior 

 angles a little emarginate and the base distinctly lobed. Elytra 

 scarcely so broad as the thorax, about twice as long as wide, 

 squared at the base, the humeral angles prominent and the sides 

 nearly parallel, with four rows of distinct fovese on each elytron, 

 each row of about six fovese, the sutural row of fovese smaller 

 than the others, but all with a brilliant bright blue bottom, the 

 rows are separated by slightly rounded costte, and there is a deep 

 lateral groove occupied by a row of strong pimctures. 



Length, 7 lines. 



Ilab. — Coonabarabran. 



The other sub-family of Scaritidse^ that with curved and 

 acutely pointed maxilla?, is not so numerously represented in 

 Australia as the Carenides, and is moi'eover not so exclusively 

 Australian. The described Australian species consist of 6 species 

 of the genus Geoscaptus, a genus formed by Baron de Chaudoir 

 for some insects closely resembling the true Scarites ; 3 species of
