on lateral lobes and with caudal portion of disk light grape green, 

 ventral margins of lateral lobes rather broadly cream color. Teg- 

 mina grape green, this weakening in areolae and heaviest toward 

 the pale oblique transverse veins of the discoidal field and pale 

 oblique veinlets of the scapular fields, the entire costal margin 

 cream color, this rather broad proximad. Limbs buffy with a 

 greenish tinge, the tarsi somewhat embrowned. Ovipositor 

 ochraceous-buff, with distal portion blackish brown. In the 

 allotype the transverse veins and veinlets are less contrastingly 

 paler and, as a result, the distinctive coloration of this insect is 

 seen to be far less pronounced in the male sex.

The pronotum in this specimen is not densely granulose, as later 

 described by Brunner. The median carina is decided and irregu- 

 larly tuberculate, the tubercles in places forming two irregular 

 adjacent lines; 66 the other portions with scattered, minute tubercles, 

 except the ventral margins of the lateral lobes, which are more 

 strongly tuberculate. 



The presence of a longitudinal spurious vein, running througn 



the narrow anal field to near the tegminal apex, combined with 



other striking characters, will probably oblige separation of this 



species from Morsimus, when the forms here assigned are better 



known. 



CHONDRODERELLA new genus 



The present genus is erected to include the new species, C. sex- 

 guttaia and very probably rubromarginata (Haan), of which it is 

 likely that borneensis (Brunner) is, at least in part, a synonym. 



Genotype. — Chondroderella sexguttata new species. 



Agreeing very closely in all other features with Chondrodera 

 Karsch, this genus may be separated by the following characters. 

 Tegmina with anal field lacking a spurious vein; discoidal and 



66 This shows some slight divergence toward the genus Chondrodera.
