on shoulders, tubercles and tegulae, lower part of pro-

 sutures between the meso- and metathorax, lateral basal 

 margins of scutellum, post-scutellum faintly, front coxge,

 tarsi fuscous ; middle of abdomen faintly reddish ; apex

? . Hardly differs from the male. My specimen has 

 the post-scutellum yellow-marked, the marks on the 

 scutellum larger, and the brown spots on the breast 

 replaced by red ones ; the coxae more yellow, this colour 

 extending to the hind pair ; the prothorax is almost 

 entirely yellow. 



Head not buccated, slightly narrowed behind the eyes ; 

 apex of clypeus sinuous ; mesopleura reticulate, with 

 fine scattered punctures; supero-medial area of female 

 distinct, less so in the male ; postero-medial the same ; 

 keels on the 1st abdominal segment of the male distinct, 

 extending just beyond the middle, obsolete in the female, 

 the segment half as wide at the base as at the apex, and 

 one-half longer than wide ; 2nd in male quadrate, female 

 transverse ; the 3rd in male and female longer than 

 wide ; parapsides of mesothorax distinct. Areolet trans- 

 verse, more or less petiolated ; transverse anal nervure 

 subopposite, interrupted a little below the middle. 



This insect should come next of M. sylvarum, Holm., 

 Disp. Syn. Mesol. Scand. 10, 19. 



M. sylvdrum has the coxfe black-marked, and meso- 

 pleura black ; in this the latter is yellow, and the coxae 

 are red and yellow. 



Bred by Mr. J. E. Fletcher from cocoons of Lophynis 

 pini, sent by- Mr. Cameron from Scotland. 



Trematopygus atratus, Holm. 



Holm., Mon. Try. Suec. 181, 4, <? ; Brischke, l. c, 



90, 5^ , ? . 

 This fine species has been taken, and bred from Croesus 

 septentrionalis, by Mr. Wilson at York. 



Brischke has placed Tryphon albipes in this genus ; 

 Marshall placed it in his Catalogue as a doubtful Tryphon.
