128 BRITISH ICHNEUMONS. [Hemiteks. 



of the head is quite white and somewhat uneven. There are thirteen 

 segments, which are distinctly discreted ; tlie fifth to the ninth bear 

 obvious dorsal prolegs, marked with black points. There is an apparently 

 irregular distribution of the white sub-cutaneous granules. On the i8lh 

 one of these larvae had fallen out of the web and the other two had begun 

 to spin cocoons fur themselves within that of the spider and were preparing 

 to pupate, since all the spiders' eggs upon which they had been subsisting 

 were sucked quite dry, only the old husks remaining. On the 22nd the 

 loose larva was still (juite lively, but had changed its colour to primrose 

 and pink, and it subsequently died ; the other two had now completed 

 their cocoons, which were spun within that of the spider and were white 

 throughout, parallel-sided and slightly wrinkled longitudinally as in 

 figure 3. On 12th May, 1901, one female Hemiteles varitarsus (described 

 above) emerged from one of these two cocoons, the second specimen 

 having apparently died during the winter. In Marshall's collection (in 

 Brit. Mus.) are specimens from Niton in the Isle of Wight, Leicester and 

 Botusfleming, together with a spider's nest affixed to a grass-stem from 

 which the imago or imagines had emerged. Beaumont took a male at 

 Coshane in the middle of July, 1891 (in coll. Chitty). 



8. capreolus, Thotns. 



Hemiteles Capreolus, Thorns. O. E. x. 970 ; Schm. Term. Fiiz. 1S97, p. 507, 6 ?. 



Head narrowed behind the eyes ; peristomium small, frons nitidulous, 

 vertex large and centrally angularly emarginate ; mandibles red, genal 

 costa continuous ; clypeus mutic. Antennae elongate, of $ fusiform- 

 setaceous ; scape excised and sub-globose. Thorax black ; pronotum 

 with a short central carina, laterally foveate ; mesonotum dull ; metathorax 

 with two distinct transverse, but obsolete longitudinal, costae. Abdomen 

 with the second, and in $ also third, segment red ; post-petiole closely 

 aciculate ; terebra hardly longer than the basal segment. Legs red, hind 

 ones fuscous-marked ; anterior trochanters flavidous. Wings not fasciated ; 

 radial nervure emitted from almost beyond the centre of the pale stigma ; 

 nervellus opposite and intercepted. Length, 4-5 mm. 



At once known from //. ifijirtnus, scabriculiis, etc., by the opjoosite 

 nervellus, posteriorly narrowed head, glabrous frons and emarginate vertex. 



Bridgman took the male near Norwich and tells us that Dr. Capron 

 captured the female at Shere, but I do not find it in his collection (jutis. 

 tnei) ; these specimens were both confirmed by Thomson, who originally 

 bred the species from rose-galls (? Rhodites rosae). Bignell records it 

 from Plym bridge and Oreston in Devon, in August and September, but 

 elsewhere it appears to have only been mentioned from Sweden.
