PARASITIC HYMENOPTERA AND TENTHREDINID^. 121 



testaceous ; the petiole and the dorsal basal half of the second and 

 third segments black ; the basal three segments are closely minutely 

 punctured, the first more strongly than the others. Legs rufous ; the 

 posterior cox® black; the hinder tibife and tarsi pale testaceous, almost 

 white ; there is a black band near the base of the hinder tibiae, and a 

 slightly broader one near the apex ; the tarsi are darker-coloured, with 

 the joints paler at the base. 



Larsephna flavolineata, sp. nov. 

 Black ; the second and following segments of the abdomen brown- 

 ish, their apices narrowly banded with pale yellow ; legs rufo-fuscous ; 

 the four anterior coxse and trochanters pale clear yellow ; the hinder 

 coxae and the basal joint of the trochanters black, the apex of the coxae 

 and the apical joint of the trochanters pale yellow ; the base and apex 

 of the hinder tibia black ; wings clear hyaline, the stigma and nervures 

 fuscous. 2 ' Length, 4-5 mm. ; terebra, 2 mm. 

 Hab. Corazon, 12,000 ft. 



Thorax smooth and shining, the mesonotum shagreened, the apex 

 of the median segment brownish ; the metapleural keel indistinct. 

 The narrow yellow bands on the apices of the abdominal segments are 

 distinct on all the segments, and extend on to the ventral surface ; 

 the petiole is deep black ; the segments becoming successively brighter 

 and more rufous in tint towards the apex. The large stigma is black 

 at the costa, the rest of it is testaceous ; the nervures are fuscous. 



The differences between this species and varipes may be 

 expressed thus : — 



Abdomen for the greater part rufous, not banded with 

 yellow ; the fore coxte and trochanters rufous, 

 the metapleural keels distinct ; ovipositor half the 

 length of the abdomen ..... varipes. 

 Abdomen black, narrowly banded with yellow, the fore 

 coxae yellow, the metapleural keels indistinct ; 

 ovipositor as long as the abdomen . . . flavolineata. 



Cryptina. 

 Cyanocryptus, gen. nov. 



Transverse median nervure in hind wings broken near the middle. 

 Transverse median nervure in fore wings not interstitial. Median 

 segment reticulated throughout, and without a distinct transverse keel. 

 Disco-cubital nervure not broken by the stump of a nervure. Antennae 

 stout, ringed with white. Apex of clypeus broadly rounded, depressed ; 

 it is not separated from the face. Median segment large, with a 

 gradually rounded slope from the base to the apex ; its spiracles 

 elongated ; the sides at the apex shortly toothed ; the pleural carinas 

 of the metathorax complete. Wings uniformly violaceous ; the areolet 

 large, the sides not convergent above. Abdomen smooth ; the spiracles 

 of the second segment placed shortly before the middle. 



The body is metallic ; the parapsidal furrows do not reach to the 

 middle ; the scutellum is roundly convex, not much raised ; the abdo- 

 minal petiole is longish, slender, dilated at the apex ; the first joint of
