rather less variegated, and on the under-surface the scales are 

 much the same as on the upper-surface ; but on the present 

 species the scales on the under-surface are decidedly smaller 

 than those on the upper, and the spur on the front and middle 

 tibiae is inserted at the top of the apex and continuing to its 

 length, diverging from it at an angle of nearly thirty-five 

 degrees (fig. 4). 



CHRYSOMELIDAE. 



Edusa pulchea, n. sp. 



o* . Metallic-green or greenish-blue with a coppery gloss 

 in parts; labrum, palpi, antennae, and legs castaneous; the 

 apex of palpi, apical joints of antennae, and last two joints of 

 tarsi infuscate ; the labrum and sides near eyes furnished with 

 pale depressed setae, and the front angles of prothorax 

 pubescent. Under-surface metallic-green with coppery gloss 

 and lightly clothed with pale pubescence, sparse in middle 

 and somewhat dense at sides. 



Head with numerous clearly-defined punctures, except at 

 base of antennae, and a slight depression at the occiput. 

 Antennae rather long with second joint about half as long 

 as third. Prothorax with front angles acute, sides subsinuate, 

 punctures as on head but becoming denser at margins. 

 Scutellum transverse and almost impunctate. Eh/fra almost 

 parallel-sided to beyond the middle, with dense punctures set 

 in somewhat irregular rows, some of them confluent at the 

 sides. Abdomen with a few scattered punctures, and the 

 apical segment has a shallow transverse depression. The hind 

 tibiae are suddenly dilated near apex (fi^. 6). Length 

 ? , Q) } 5-6 mm. 



O . Differs in being more robust, the hind tibiae not 

 suddenly dilated near apex (fig. 7), first joint of front tarsi 

 smaller, the abdomen more convex and without the subapical 

 depression, and more pubescent.

This apparently belongs to the glabrous group of Edusa 

 and in Lea's table (2) would be referred to C o, but that the 

 sides of its prothorax are almost straight in the middle, hence 

 it could not be referred to either anrjuzfula or heterodora : 

 in general appearance it is like a rather robust hf-terodor <a, 

 but the abdomen is metallic and its fifth segment is different 

 in the male.
