1920. J 3J 



Of Palaestra I can recognize three species as follows : — 



1. Head triangular, widest behind eyes, vertex deeply cleft ; thorax with wide 



median furrow throughout, sides strongly excised in anterior half, an- 

 terior discal impressions very large, following lateral emarginations. 



2. 



Head more elongate, widest across eyes, vertex feebly impressed ; thorax 

 strongly narrowed in front, the sides sinuate, feebly emarginate, median 

 furrow distinct only in basal half, anterior pair of discal impressions deep 

 and round, similar to posterior pair; intervals between elytral costae 

 densely, rather coarsely punctate .foveicollis, sp. n. 



2. Thorax subopaque, rather densely punctate ; intervals between elytral costae 



granulate rubripennis Cast. 



Thorax nitid, very sparsely punctate; intervals between elytral costae 

 punctate-rugulose, forming a partial intermediate costa in second 

 interval rufipennia Westw. 



P.foveicolliSf sp. n. 



Elongate, black, subuitid, elytra red. Head elongate-triangular, not 

 widened behind eyes, densely rugose punctate, vertex feebly impressed, 

 Clypeus almost impunctate in front ; labrum rather transverse, with median 

 impression, lightly emarginate at apex. Antennae more than half as long as 

 body, the joints compressed and expanded, 3rd to 6th about half as long again 

 as their width at apex, 7th to 11th successively narrower. Thorax widest in 

 middle, its width at apex about half tliat in middle, the sides feebly sinuate, 

 scarcely excised, in apical half ; disc with a strong median furrow in basal 

 half, and two pairs of deep round foveae, the posterior pair separated by the 

 median furrow, surface plainly but not closely punctate. Scutellum rounded 

 at apex, densely and finely punctate and pubescent. Elytra about three times 

 as long as together broad, subparallel, separately rounded at apex, glabrous, 

 each with the suture and four sharply defined costae smooth, rounded, the 

 intervals between them densely, rather coarsely punctate, the 3rd and 4th 

 costae are confluent near the shoulder, the latter gradually approaching the 

 external margin. Length 13-15 mm.

The form of the thoi-ax characteristic of Palaestra, with the sides 

 roundly excised before the middle, is but feebly developed in this species, 

 indicating an approach to Palaestricla. The sculpture of the elytra is, 

 however, Tery different from that of the latter genus, and essentially of 

 the Palaestra type. I am unable to identify P. foveicollis with any of 

 the species described ; P. quadrifoveata Fairm., to which it seems, 

 ex descr., to approach in the form of the thorax, has, inter alia, the last 

 joint of the maxillary palpi testaceous, the antennal joints prismatic, 

 scarcely dilated, and the scutellum smooth, impressed.
