Descriptions of iiffcy New Species of the Genus Stigmodera. By 

 Edwaed Saundees, Esq. Communicated by W. "W. Saunders, 

 Esq., V.P.L.S. 



(With two Plates.) 



[Eead November 7, 1867.] 



The present paper contains characters and figures of fifty unde- 

 scribed species of the genus Stigmodera from Australia. There 

 still, however, remain a large number of apparently new species 

 requiring description and further study ; for, since there is 

 great modification to be observed, both in the form and colour- 

 ing of many of the species, it is very desirable to obtaiu long 

 series of those wliich are closely allied before giving their specific 

 characters. 



In the species I now bring forward, I have had this in view, 

 and have described only those which I think will not prove to be 

 varieties of each other, leaving the more doubtful ones till further 

 evidence shall prove the specific value of their characters. 



All the species described in this paper are in my own collection. 



Stigmodera Mnizechii. (Plate IX. fig 1.) 



Viridi-nigrescens, thorace nitidissimo ; elytris rugulosis, fascia prope 

 apicem sanguinea ; subtus nitida. 



Dark greenish black. Elytra with a transverse sanguineous band near 

 the apex. Antennae purple. 



Head deeply punctm-ed, with an impressed line between the eyes, 

 covered with short whitish hairs. Thorax, once and two-thirds as 

 broad as long; anterior margin produced, half as long as the base; 

 sides shghtly rounded ; base with a shallow median lobe ; surface 

 shining and smooth, sides largely punctured neai- the lateral margins, 

 disk with a faintly impressed dorsal hne, median basal lobe terminated 

 on each side by a short longitudinal slit. Elytra once and two-thirds 

 as long as wide, sides shghtly sinuate above the middle ; apex of each 

 elytron somewhat diagonally truncate, outer angle of truncature 

 slightly dentate; disk striate and very largely punctured; as they 

 approach the sides the punctures become confluent, so as to give a 

 rugose ap])earance, especially on the shoulders. Beneath of thorax, 

 breast, first abdominal segment and legs, punctured, and slightly 

 hairy. The rest of the segments polished, with a slight impression 

 on each of their sides. 



Length 15 lines, breadth 7.

Stigmodera Bonvouloirii. (Plate IX. fig. 2.) 

 Capite thoraceque cyaneis fortiter punctatis et rugulosis, elytris sangui- 

 neis duabus maculis cyaneis notatis, subtus cyanea.
