Body smooth and graceful, not strongly and elongately pilose. 

 .Anteuuce as long as body, more or less slender, with the apical 

 joints cylindrical and not discrete. Notauli often anteriorly 

 dist-inct, metathoracic costaj entirely wanting, metapleurae longi- 

 tiulinally subsulcate near the quite circular spiracles. Scutellum 

 somewhat convex and usually pale-marked ; frenum pale. Abdo- 

 men smooth, with a shining bloom and not punctate, often with 

 the segments pale-margined ; anus usually subcompressed ; bypo- 

 pygiuin retracted ; basal segment convex and not carinate ; 

 spiracles of the second close to the lateral margin ; terebra longer 

 than half, but not the ^A■hole, abdomen. Tibiae spinulose, witb 

 their calcaria elongate ; tarsal claws ver}^ closely and distinctly 

 ])ectinate. Areolet broad and obliquely triangular, emitting the 

 recurrent nervure from hardly before its apex ; nervellus iuter- 

 ce])ting below the centre, sometimes at tlie lower angle.

 Ceylou. 



(xravenhorst placed this genus in the Cryptix.e, along with 

 Mesocliovus and Plectiscus, which are now regarded as Opiiio^'ix.e. 

 But his genus has been considerably subdivided by subsequent 

 authors and only three of the original twelve species and the 

 anomalous P. corvimis are now retained therein. Their subf usiform 

 abdomen and thorax, attenuated basal segment and slender legs 

 certainly ally them with the CryptinvE, while the occasionally 

 subcompressed anus resembles that of the Ba>X'1IIDes ; they are, 

 in particular, very liable to bo mistaken for the Try]:»honine 

 3Ji'Soleiu!^, from which it is ditiicult to instance any male distinction, 

 though the females are rendered obvious by their exserted terebra.
