230 liev. T. A. Marshall's vwnograph of 



Briscbke ; and in England by Bridgman, Bignell, Brown, 

 Wilson, Fitch, and myself. The broods, consisting of 

 a dozen individuals, or less, are excluded in the middle 

 of September, and remain as pupa3 till the following May 

 or June, Cocoons greyish brown, rough, longitudinally 

 and irregularly wrinkled, naked, strong, and closely 

 agglutinated together. From one of Brischke's cocoons 

 api)eared the hyperparasite Mesochorus splendidulus, Gr. 

 Eatzeburg reports that in Germany Bachmann obtained 

 a ? on Sept. 22nd from Acronijcta psi, L., which became 

 an imago on the 14th of April following ; but the 

 observation is given doubtfully. 



4. Microplitis vidua, Ruthe. 



Microgaster viduus, var., Ruthe, Berl. ent. Zeit., 1860, 

 p. 134, <y ? . 



Black ; palpi more or less pale ; sides of segment 1 narrowly, 

 and legs, testaceous ; coxae and upper trochanters, fore femora at 

 the base, the others wholly or partially, black ; hind tarsi iufus- 

 cated. Wings infumated, squamulie black, stigma and ner\aires 

 fuscous. Antennte $ a little longer than the body. Head, meso- 

 thorax, and scutellum dull, finely granulated, Metathorax rugu- 

 lose, subreticulated, subcarinated. Abdomen smooth and shining, 

 except the 1st segment, which is rugulose, about 1^ times longer 

 than broad, with parallel sides almost to the apex, and then 

 broadly rounded. Terebra svabexserted, and, with the valvula ven- 

 tralis, much shorter than the anus. $ $ . Length, If ; wings, 4 lin. 



The typical form, which I have not seen, differs, 

 according to Ruthe, in being short and compact, for he 

 compares it with the larger examples of ocellatce, Bouche, 

 The metathorax is less coarsely rugulose, the 1st segment 

 a little broader, and its sculpture almost obsolete. The 

 var, is intermediate between this form and tuhcrculifera, 

 Wesm,, from which it is distinguished by the broader 

 1st segment, not attenuated towards the apex ; the pos- 

 terior femora are black, the stigma unicolorous, and the 

 cocoons different. 



There arc three British specimens at hand ; one <? taken 

 by me in Leicestershire, and a ? bred by Bignell from 

 T(e)nucampa incerta, Hufn. ; a ^ April 28th from an 

 unknown victim by Billups, Briscbke bred it from 

 tivierintliusjx'puli, L. The cocoon is more or less brownish 

 grey, and most resembles that of M. tuhcrculifera, Wesm., 

 but is larger and more irregularly wrinkled.
