and pulvilli stout. Wings with the stigma narrow and with no 

 areolet ; apical abscissa of radial nervure nearly twice as long as 

 the basal ; lower angle of discoidal cell subacute ; fenestne dis- 

 creted and not small. Lower wings with the first recurrent very 

 strongly postfurcal and intercepted by the uervellus far above its 

 centre ; second recurrent centrally pellucid. 



Range. Europe, North Africa, China and Ceylon. 



This genus was for long treated as appertaining to the OPHIO- 

 KIXJB ; its stout and elongate hind legs, very indistinctly sub- 

 petiolate abdomen, cubical head, and the conformation of the 

 mouth parts and antennae certainly ally it far more closely with 

 Acttnitus, as was indicated by Thomson in 1877 ; and it appears 

 to bear only a very distant analogy with Pristomerus vulnerator, 

 its congeneric species in the Gravenhorstian system, which is a 

 true Ophionid aud closely related to the genus Cremastus. 



Motschulsky's description of our two species is so short and 

 vague that it is quite impossible to tell nowadays whether they 

 should be placed in the PIMPLIKJE or OPHIONIN^E ; but, since no 

 mention is made of femoral dentation, it is far more probable 

 that, if correctly placed in the Gravenhorstiau genus by their 

 author, they should now find a place in that of Schiodte ; but 1 

 have seen nothing similar from Ceylon. 



Table of Species. 



1 (2) Shining ; antennae basally and petiolar fascia 



red unifasciatus^ Mots. 



2 (1) Dull ; antennae basally infuscate ; petiole 



black gracilipes, Mots. 



14. Collyria nnifasciatus, J/ota. 



Pachyments unifasciatus, Motschulsky, Bull. Soc. Imp. Nat. Moscou, 

 1863, p. 29. 



An elongate, nitidulous, black species, with the head nearly a 

 quarter the length of the whole body in breadth. Head deplanate 

 and shining, with the clypeus densely and finely punctate and 

 pilose ; eyes large, with a brazen reflection ; palpi testaceous-red. 

 Antennas basally testaceous-red. Thorax with the rnesonotum as 

 broad as the head, glabrous, with the notauli deeply impressed and 

 basally convergent. Abdomen slender, compressed and subtri- 

 angularly dilated posteriorly ; basal segment with the petiole 

 elongate and black, with a testaceous-red fascia. Legs testaceous- 

 red, with paler coxal marks ; the hind femora simple, narrow and 

 centrally, like the apices of their tibiae, subinfuscate. 



Length 4 raillim. Sex not noted. 



CEYLON : Nuwara Eliya (teste Motschulsky). 



It should be noted that in the original descriptions of this and 

 the following species their author appears to have transposed our 

 modern rendering of the terms pro- and mesonotum ; thus, he 

 writes of P. unifasciatus " pronoto capitis latitudine, longitudi- 

 naliter biimpresso " and of P. ymcilipes as " pronoto subovato."
