lincarl)' transimprcsscd; niL'tatlutrax diTply iinijrcssL'd basally with elon- 

 gate spiracles and distinct areai>, of which the areola is strongly eh^ngate 

 and laterally strongly carinate ; petiolar area short and small ; apophyses 

 dentitbrni and somewhat strong. Scutellum not laterally carinate. Ab- 

 domen petiolate and compressed ; basal segment straight, with spiracles 

 a little before centre and lateral basal sulci deeply impressed. Legs 

 slender ; tarsal claws somewhat largt' and stoutly p(>ctinate. Wings sub- 

 ample with areolet complete, small and triangular, emitting recurrent 

 nervure from its apical angle ; stigma very narrow, emitting radius almost 

 from its base ; apical abscissa of radius distinctly, though slightly, curved 

 above areolet ; nervellus intercepted above centre. 



A Tenthredinid parasite appears anachronous in the jjresenl group, 

 with which this genus is too naturally related to be relegated to the 

 Tryphonini, yet there is a good deal of analogy with Scolobatcs in its struc- 

 ture, especially that of the head.

A large rufesct'nt-testaceous sj)ecies with the anus, and more or less of 

 the thorax, black. Head extremely broad behind ihr r\-es, with frons 

 and ocellar region and apex of occiput black. Antennae apically nigres- 

 cent. Metathorax finely pun(.:tate with variable but usually very strong 

 carinae ; areola sublinear, not extending to base, with its apical costa 

 strongly reflexed. Abdomen slender and nitidulous, pale with anus from 

 apex of fourth segment deep black and terebra testaceous. Legs immac- 

 ulate or with the coxae basally black. Wings strongly flavescent and 

 apically slightly infumate; stigma clear red and nervures piceous. Length, 

 20-22 (or abroad, -26) mm. 



Very widely distributed; it is said to occur on umbels in August, and 

 in June in Clcrmany where it has been often captun-d at light, and seen 

 flying round aUK-rs as late as October; .Sweden in August; Fraut'e ; Hol- 

 land in August; Italy; I have females taken by Montandon at Hucharest 

 and Dobrudja in Roumania, together with a single example of the undes- 

 cribed male of the southern var. /i/sr/'/x/i/iix ((ir. LI'", iii. ()35. V). which 

 differs in nothing but its anal appendages from its female, and both from 

 the type form only in their deei)ly infumate wings. It has long been, 

 known to be parasitic upon species of the Tenthredinid genus Cinilitx : 

 bred from C. variabilis {■=^ fanorata) by Hartig (Jahresb. <)1S) ; 2olh ^L1y,
