cent; mcsonotum, t-spccially ol J, usually ac-icuhitc ; niclallujrax with 

 complete upper areae and centre of" petiolar area nearly double lenfrth of 

 its sides. Scutellum often red. Abdomen hardly loni:;er than head and 

 thorax, black with first sej,niient basally dull testaceous, apex of second 

 subtriant>ularly rufescent and third discally red to beyond its centre ; fol- 

 lowinji^ segments of 9 laterally pale, and the ^ styls and ventral plica 

 flaxidous; basal segment slightly curved, witli postpetiole usually foveate; 

 second and third segments transverse ; terebra subulate, very slender and 

 shorter than basal segment. Legs testaceous with hind tarsi concolorous, 

 their tibiae nigrescent at both extremities, and coxae usually discally 

 infuscate-marked. Wings hyaline with tegulae whitish, and the apically 

 curved radius basally emitted from apical third of the narrow and testa- 

 ceous stigma; areolet large and sessile, emitting recurrent nervure slightly 

 before its centre ; lower basal nervure antefurcal. Length, 5-6 mm. 



The last four species of this genus differ from ali the preceding, except 

 perhaps the conspicuous first group (before M. vi/licollis), in their small 

 size and in having the ocelli not large, the flagellum usually slender and 

 filiform, occipital line behind the C3'es often slender or obsolete, lower 

 basal nervure usually postfurcal, second recurrent somewhat short and 

 but slightly longer than breadth of the often sessile areolet, abdomen 

 apically compressed from base of third segment with the second trans- 

 verse and broader apically, terebra slender and nearly subulate though 

 not short, hind calcaria not extending to centre of metatarsi, and itolh 

 claws and pulvilli small. 



This sj)ecies appears but little known, though vaguely recorded from 

 north and central Europe by Thomson ; Jirischke gives some colour forms 

 as doubtfully belonging to it, which he bri'd from Hficiog^is/cr cocoons 

 out oi P/usia gamma, Cucullia astcris and C. argcntea, and Argvniiis Lalonia 

 larvae in Prussia. In Britain Capron records it from the neighbourhood 

 of Shere in 1879 (Entom. 1880, p. 89), though it is not now in his collec- 

 tion; Olliff bred it ixowx Nola ciicuUahila {Jib. cit. 1883, p. 07); and Bignell 

 in Devon from Kuchelia Jacohacac \\\xo\X'^\ Apanlchs pi^piilaris on 20th Jul}'.
