Orihopelma.] BRITISH ICHNEUMONS. II3 



I have seen two females of this insect ; one was captured at Sliere in 

 Surrey by Dr. Capron, and the ty[)e I took by sweei)ing in W'icken Fen, 

 Cambs., in the morning of 81I1 June, 1902. 



SPINOLIA, Fdrster. 

 Fiirst. Verb. pr. Rheinl. 186S, p. 173. 



Head strongly transverse, with the vertex exactly level with the summit 

 of the eyes, from which the ocelli are not far distant. Antennae very 

 slender, with more than twenty joints, of which the second flagellar is 

 not longer than the first ; cubital transverse nervure of the upper wings 

 wanting. Metanotum areolated ; its spiracles small and circular. Scu- 

 tellum bordered throughout. Basal segment distinctly petiolate ; the 

 third alone transversely impressed. Legs slender. ^Vings of $ very 

 strongly fasciated ; both sexes with the areolet entirely wanting externally 

 and nearly obsolete internally. 



The facies of this genus, together with its profuse rufescent coloration 

 and the female fasciated wings, render it doubtful whether Hemiteles 

 areafor, bicoiofiniis, hngicauda and, perhaps, ci/ii^i/Iaior should not also be 

 included here, though differing more or less widely from certain of the 

 generic characters ; H. bicolorinus may be distinguished from all other 

 members of that genus by the irregular inner nervure of the areolet, being 

 transitional between Hemiteles and the present genus, which has not before 

 been employed by systematists. I am certainly of opinion that Forster's 

 genus Catalytus (1850) should be placed here; the alar development, 

 which abundantly distinguishes our two species, being the most pro- 

 nounced distinction.

9 . A rufo-testaceous insect with boldly fasciated wings. Head black, 

 triangular, with prominent eyes ; vertex narrow and declived ; cly[)eus dis- 

 creted and apically produced ; epistoma prominent ; mandibles with acute 

 teeth, of which the upper is nearly the longer. Antennae filiform, nearly 

 as long as the body, with twenty-seven flagellar joints, of which the basal 

 are apically nodulose ; black with the three central, and rarely the three 

 basal flagellar joints blood-red. Thorax subslriate-rugose, with white 

 pilosity, sometimes entirely black but usually rosy with the pronotum, 

 l)reast, scutellar region and more or less of the metathorax, black ; notauli 

 reaching centre of the deplanate mesonotum, mesopleurae rugose but 

 glabrous above ; metathorax reticulate with the areae complete and well- 

 defined, areola narrow-hexagonal, petiolar area large but not discreted. 

 Scutellum often red ; laterally margined throughout. Abdomen ovate, as 

 broad as the thorax ; black, with the first segment except sometimes two 

 dorsal dots, second and basal angles of the third, or only the apices of the 

 first and second, rf)sy ; sixth and seventh apically whitish ; basal segment 

 stout, curved, longer than broad and gradually dilated apically, densely 

 striolate with neither carinae nor tubercles ; third segment transversely
