PANI LUPUS. ERYSTUS. 



271 



Head impunctate, without frontal elevations or carina; clypeus 

 broad between the bases of the antennae; apical segment of 

 maxillary palpi acute and conical. Antennae robust, long, being 

 only a millimetre shorter than the length of the body; first 

 segment club-shaped, elongate, second small and rounded, third 

 and fourth nearly equal ; the seven terminal segments gradually 

 and slightly thickened, apical segment pointed. Prothorax 

 broader than long, sides slightly rounded, anterior and posterior 

 lateral angles nor, produced, slightly thickened, and having each a 

 seta-bearing pore ; basal margin rounded, surface convex and im- 

 punctate. Scutellum, triangular, smooth, and im punctate. Elytra 

 slightlv widened towards the apex, broader at base than prothorax,. 

 base with a very shallow depression ; finely punctate, the 

 punctures being arranged in irregular and closely approximated 

 rows; on either elytron there may be twenty-one or twenty-two 

 rows, but owing to their irregularity the number cannot be 

 exactly determined. Underside impunctate.

 somewhat costate, lateral margins broadened, their epipleura very 

 broad, concave when seen from the ventral side. Underside: 

 anterior coxal cavities closed ; prosternum rather broad, obsoletely 

 carinate ; posterior femora strongly incrassate ; tibiae short, 

 dilated at the apex, the four anterior tibiae unarmed, the posterior 

 pair with a small spine (in the genotype, but this spine is absent 

 in E. andamanensis) ; their dorsal surface obsoletely channelled ; 

 tarsi broad and short, nearly equal in length ; claws appendiculate.
