ABBASTARTUS. ]03 



Genus ABDASTAKTUS, nov. 



Type, A. tyrianus, Dist. 



Distihution. At present only received from Bengal. 



Head broad, large, subquadrate, two central slightly curved 

 longitudinal ridges, the apices of which slightly project in front as 

 short spines, two long porrect spines between the basal joints of 

 the antennae, and a short curved spine on each side slightly behind 

 and above the insertion of each antenna ; antennae with the first 

 and second joints moderately thickened, first a little longer than 

 second, remaining joints mutilated in specimens now before me ; 

 pronotum large, without an anterior hood, centrally moderately 

 tranversely gibbously raised and completely covering scutellum, 

 the anterior lateral margins laminately carinate, the disk tricarinate, 

 the central carinatiou straight and continuous, the lateral cari- 

 nations shorter, a little curved, not reaching the anterior margin ; 

 elytra long, narrow, the costal margin sinuately waved, narrowest 

 at base and gradually widened touards apex, the apical margin 

 rounded, tlie discoidal area short, broad, subovate, narrowed 

 anteriorly and posteriorly, the subcostal area a little broader than 

 the costal area, the sutural area large and occupying more than 

 half of the elytra, the costal area complete, opaque, remaining 

 areas areolate ; the areolets of the subcostal area small, those of the 

 discoidal area larger, and those of the sutural area largest; legs 

 moderately long and slender. 



This description is based on several specimens kindly sent me 

 by Mr. Maxwell Lefroy, but which unfortunately became more or 

 less mutilated in transit, the antenna) in all being deficient beyond 

 the first and second joints. It thus becomes difficult to locate the 

 genus precisely in the method pursued in this Indian enumeration, 

 though it is probable that in placing it after Phatnoma no con- 

 siderable error will have been committed.
