uniformly fuscous violaceous. Temples nearly as wide as 

 the eyes, strongly roundly narrowed. Basal two joints of 

 flagellum equal in length. Body metallic. Tarsal joints 

 strongly spinose. Metapleural keel complete. 



Type : Cry phis Kinbergi, Holmgren, from Buenos Ayres, 

 " Eugenies Resa," p. 397. 



Allied to Cyanocryptus* Cam., which may be known from 

 it by the metanotum being without transverse keels, by the 

 transverse median nervure in hind wings being broken close 

 to the middle, by the metanotum having a gradully rounded 

 slope from the base to the apex, which is not the case with 

 the present species. 



In the arrangement of Ashmead (Bull. U. S. Nat. Mus., 

 xxiii., p. 43) this genus runs close to Pyncocrptus, Thorns. ; 

 in that of Schmiedeknecht (Opus. Ich., Fasc. vi) it would 

 also run near that genus, except that the hind femora are not 

 thick, the hind tarsi short (in the present genus long), there 

 is only one keel on the metanotum, the metathoracic spira- 

 cles are oval ; the hind tarsi are shorter than the tibiae, in 

 Lamprocryphis as long as them and the metanotum is not 

 toothed, nor is the body metallic, nor the wings uniformly 

 violaceous. In Lamprocryphis the metanotum is closely re- 

 ticulated, the abdomen finely, minutely punctured and the 

 ovipositor is shorter than the abdomen.

The propleuree are longitudinally striated, finely above, 

 more strongly below ; the scutellum is very shining and only 

 very sparsely punctured ; the metanotum is closely reticu- 

 lated ; the coxae are blue and violaceous, the trochanters 

 have the basal joint blue, the apical black ; the fore tarsi are 

 colored like the tibiae, but slightly darker in tint ; the middle 

 pair are infuscated, except at the base, the posterior black, 

 the apex of the hind tibiae being also black. 



Cryptus chalybaeus, Tasch. Zeits. f. d. ges. Naturwiss., 

 xlviii., p. 63, is a closely allied, if not identical, species.
