fit aciitideiis, but in that species the rostrum is not subulate and 

 the femora are strongly dentate. 



Genus Psydestis, Pascoe. 



Ann. Mag. Nat. Hist. (4), xiii., 1874, p. 412. 



Head small, not concealed by prothorax; ocular fovea not trace- 

 able. Byes moderately large, subovate, finely faceted. Rostrum 

 short, scarcely the length of prothorax, moderately stout, almost 

 parallel-sided, feebly curved. AnteniicB slender; scape inserted 

 nearer base than apex of rostrum, slightly shorter than funicle; 

 two basal joints of funicle elongate; club of moderate size, joints 

 distinct. Protliorax convex, transverse, apex scarcely produced 

 and more than half the width of base, base truncate; constriction 

 feeble ; ocular lobes obtuse. Scutellmn small, subquadrate. 

 Elytra convex, subcordate, not much wider than prothorax, 

 shoulders and apex rounded. Pectoral canal extremely short in 

 front of anterior coxjb, these moderately separated. Mesosternal 

 plate strongly transverse, very feebly concave, apex slightly wider 

 than base. Mefasternum large, shorter than basal segment of 

 abdomen; episterna large. Abdomen moderately large, sutures 

 distinct ; 1st segment longer than the three following combined, 

 intercoxal process widely rounded; intermediates combined longer 

 than 2nd or apical. Legs moderately long; femora stout, clavate, 

 posterior strongly, intermediate feebly dentate, anterior edentate, 

 posterior extending to apex of elytra; tibise somewhat rounded, 

 feebly bisinuate beneath, the four anterior each terminated by a 

 small but strongly recurved hook, terminal hook of posterior 

 scarcely visible; tarsi stout, 3rd joint wide, bilobed for half its 

 length; claw -joint thin, scarcely half its length exserted, claws 

 feeble. Widely ovate, convex, squamose, punctate, winged. 



Resembles Lylceha in many features, but may be distinguished 

 on account of the rostrum, eyes, and very short 2nd abdominal 

 segment. Dietlmsa* appears to be very close, but as Mr. Pascoe 

 describes the two basal segments of the abdomen as " ampliatis " 

 it may be distinct; his description of the tibise, however, exactly
