together with a ring before the base, and all the tarsi, fuscous. 

 (? ? . Length, 2:^ ; wings, 4^ lin. 



Eyes during life of a fine green colour. Antennae as long as the 

 body, fuscous towards the apex, 23-joiuted. Head subcubical, 

 pubescent ; face carinated. Metathorax with an abbreviated 

 medial transverse carina. Abdomen subdepressed, segments 1 — 2 

 transverse, rimulose, the 1st with two basal cariuEE, converging 

 and vanishing before the middle ; the 3d longer than broad, more 

 finely rimulose, truncate at the apex, and with a gibbosity just 

 before the truncature, indicating the posterior limit of the segment ; 

 both the sutures crenulate. Wings slightly fuscescent, nervures 

 and stigma brownish, the latter pale at the base ; before and 

 behind it is a decolorous streak ; 2d cubital areolet much attenuated 

 outwardly ; radial areolet approaching the apex of the wing. In 

 the hind wing the radial areolet is constricted in the middle, where 

 an imperfect transverse nervelet almost joins the costa. 



Var. a. Fusco-ferruginous, uniform, orbits and legs paler ; hind 

 tibias more broadly fuscous ; wings without hyaline streaks. 



Var. /3. Ferruginous, disk of the mesothorax fiiscous with a 

 pale patch anteriorly bifid ; abdomen fuscous, segment 1, and 2 at 

 the base, more or less pale. 



Var. y. The same, but the vertex and pectus are also fuscescent. 



Var. 8. Thorax and abdomen entirely fuscous. 



In the darker varieties the hyaline streaks on the 

 wings are more distinct, the orbits are rufous, and the 

 hind tibiae more highly coloured. 



Not uncommon in Southern and Central Europe. I 

 have a specimen which I took in Corsica. Eare in 

 England, but one was captured by Dale in Stilton Fen, 

 Huntingdonshire, August 14th, as recorded by Curtis, 

 B. E., 672. Another was in Walker's collection. Several 

 were taken at Dover by Sydney Webb, in a warehouse, 

 in August, and conjectured by him, with great proba- 

 bility, to be parasites of Mi/elo'is ceratonice, Zell., occur- 

 ring in the same warehoiise. A specimen has also been 

 captured by Billups. Obtained by Eeissig from a Tortrix 

 larva living on the oak ; by Brischke out of liJiodopJifea 

 advenella, Zinck., from Silesia.
