PARASITIC HYMENOPTERA AND TENTHREDINID^E. 97 



ginous ; the coxre and trochanters black, and there is a broad black 

 band ou the under side of the hinder femora at the apex ; the wings 

 are hyaline ; the stigma light, the nervures dark, testaceous. (? . 

 Length, 10 mm. 



Hab. Hac. Antisana, 13,300 ft. 



Antennae black, stout, distinctly tapering towards the apex ; short, 

 not much longer than the head and thorax united. Head black, the 

 inner orbits narrowly yellow ; strongly and closely punctured, except 

 the clypeus and the lower part of the front ; the clypeus smooth, with 

 an irregular row of punctures round the top and bottom. Mandibles 

 black, broadly rufous in the middle. Palpi pale testaceous and covered 

 with white pubescence. Thorax closely and strongly punctured, and 

 thickly covered with white pubescence ; the basal half of the propleurse 

 is smooth in the middle, sparsely punctured on the top and bottom ; 

 the punctures on the apical half are close, large and elongate. The 

 scutellum is punctured ; the punctures are smaller and more widely 

 separated than they are on the mesonotum. Metanotum irregularly 

 rugosely punctured ; the posterior median area is closely transversely 

 striated. Legs rufo-testaceous ; the coxae and trochanters are black ; 

 the tarsi are thickly spined. The petiole is sparsely punctured ; the 

 post-petiole impunctate ; the second segment is obscurely punctured 

 round the edges ; the gastrocooli smooth, shallow ; the third segment 

 is closely, but not very strongly, punctured ; the others are smooth. 



Hbmitelini. 



Larsephna, gen. nov. 



Median segment with two distinct transverse keels and no lateral 

 ones. Metathoracic spiracles oval. Discoidal cellule closed at apex. 

 Transverse median nervure in hind wings not broken ; the first 

 abscissa of radius half the length of the second. Antennae 22-jointed, 

 the basal three joints of flagellum equal in length. Parapsidal furrows 

 indistinct and widely separated. 



The eyes are large. The cubitus is obliterated beyond the areolet ; 

 the metapleural keel is complete ; the basal keel on the metanotum is 

 broadly turned backwards in the middle, and is united to the base of 

 the metanotum by two short oblique keels, which form a small area. 

 The apex of the clypeus is rounded ; the occiput is margined. Stigma 

 large, triangular. 



This genus is referred to the Hemitelini from its general body 

 form, and from the alar neuration ; but the absence of longitu- 

 dinal keels on the metanotum and its consequent absence of 

 arefe are more characteristic of the Cryptina. There is a genus 

 of Hemitelini — Chirotica, Foer. — which has not the metanotum 

 areolated ; but the present species cannot be referred to it.
