376 ICHNEUMON IDJE. 



wanting ; basal nervure continuous through the median ; base of 

 radius thickened ; glabrous area distinct, but often immaculate. 



Ran'ie. Europe, Khodesia, Ceylon, South India, Panama. 



Cameron points out that his genus is allied to Pleuroneurophion 

 and Uenicos/nlus in the basally thickened radial nervure, though 

 differing from the former in the continuous basal nervure and 

 broadly rounded disco-cubital nervure, and from the latter in the 

 (occasional) absence of corneous marks in the glabrous alar area 

 and in the nervellus being intercepted (occasionally) above the 

 centre. The somewhat uncommon fyihion bombycivorus, Grav., is 

 the tvpical species and has been repeatedly bred from the Lobster 

 Moth, Stauropus fayi, L., in Britain and Germany. The presence 

 of an infutnafe spot, considered characteristic of the genus bv 

 Cameron, cannot exclude the Following species from Prof. Sigismund 

 Brauns' genus (in Opusc. Ichn., they are separated sol ly on the 

 comparative length of the labrum), the composition of which has 

 been corrected by Kriechbaumer (Zeits. Hym.-Dipt. 1901, p. 22).

c? $ . An ochraceous species, broadly marked with black and 

 flavcus. Head glabrous and nitidulous, testaceous, with the face, 

 mouth and orbits flavous. Antenna testaceous red. Thorax with 

 three large and narrowly separated mesonotal vittae, apex of meta- 

 notum, a large and basally obliquely constricted mark on the basal 

 half of the mesopleurae, and a large suboval mark on the meta- 

 peurae, black ; pro- and meso-thorax impunctate : metanotum 

 glabrous before the transverse carina ; the base depressed, some- 

 times with two stout discal carinae ; the disc beyond the trans- 

 verse carina with three or four longitudinal carinae; the petiolar 

 area strongly regularly trans-sti-iate, its sides obliquely and 

 strongly striate, with the stria) clearly separated ; the apical 

 .slope is somewhat widely and irregularly striate ; pleurae smooth 

 and nitidulous. Scuteflum laterally carinate to near ite apex. 

 Abdomen testaceous, with the third segment discally, and most of 

 the fifth and sixth, black. Wings hyaline, with the radial cell 

 ] in sally infumate ; stigma and nervures black, with the former
