Furst. Verb. pr. Khcinl. 186S, p. 188; Liocryplus, Thorns. O. E. v. (1873), 489. 



Head sub-triangular, vertex abruptly declived ; cheeks elongate and not 

 buccate ; face broad and i)arallel-sided ; clypeus and epistoma deplanate, 

 the former broadly rounded apically ; antennal scrobes short but distinct. 

 Antennae filiforiii ; post-annellus not twice longer than scape, which is 

 excised nearly to its centre. Pronotum very short, with obsolete e[)oniiae ; 

 mesonotum not anteriorly declived, its notauli nearly wanting ; metathorax 

 very short, obliquely truncate apically ; spiracles large and oval ; meso- 

 sternum very short, with its sternauli short and broad. Abdomen arcuate ; 

 basal .segment elongate, deplanate, straight, with spiracles situated in the 

 posterior third ; second and third segments with hind margin sub-callose 

 and smooth ; terebra short. Tibiae mutic, front ones not inflated ; calcaria 

 elongate. Wings with radial cell short ; areolet very large and parallel- 

 sided ; nervellus nearly opposite. 



This genus may be distinguished from Goniocryptus by the entire and 

 not interrupted epicnemia, and by the epomiae being wanting above. 

 Only Cryptus analis and two Continental species are included in this 

 genus in the last European revision, in which C. coarctatus, Grav., is 

 utterly ignored and omitted.

Black, shining, hardly pubescent. Head immaculate ; clypeus large 

 and deplanate, apically broadly rounded and margined, and, like the face, 

 pubescent and finely aciculate transversely ; face longitudinally bicanali- 

 culate, vertex short, occiput declived ; frons fiat with central carina. 

 Antennae sub-filiform, with five central joints of $ white. Thorax black 

 metanotum very short, its lateral areae smooth in $ and rugulose in $ 

 petiolar area vertical and sub-entire, basally broad and hardly curved 

 apophyses wanting, spiracles oval. Scutellum black, difiFusely punctate, 

 nearly as broad as long, flatly convex and apically rounded. Abdomen 

 hardly convex, nitidulous, as broad as the thorax, ovate and in $ oblong- 

 ovate ; usually black, with segments two to four, apex of first and sometimes 

 base of fifth, red, or rarely mainly red ; basal segment flat, with its sides 

 straight ; post-petiole sub-quadrate, twice broader than petiole, gradually 

 dilated towards apex, shining and centrally sub-canaliculate, with apical 

 angles obtuse and in $ spiracles often prominent ; second segment
