104 Rev. T. A. Marshall's monograph of 



Wings hyaline, stigma and nervnres fiiscoiis ; cubitus and anal 

 nervure not decolorous as in Sigalphus. 



The description of the ? is from Haliday. The c? I 

 caiDtured in a wood near King's Teignton, S. Devon. 

 Eeinhard, after kindly examining this specimen, returned 

 it with the MS. name jMillidus, adding that the same 

 species occurred near Dresden. After careful examina- 

 tion I cannot find any difference between this and lepidus, 

 Hal., and I conclude them to be identical. The types of 

 lepidus were discovered by Curtis.

Head less transverse, snborbicular. Protliorax inconspicuous ; 

 metathorax hardly bituberculate. Abdomen short, ovate, convex, 

 rimulose (except at the apex) ; segment 1 transverse, imperfectly 

 bicarinated ; segment 2 shorter than 3 ; the remaining segments 

 concealed under the carapace. Radial areolet not much larger 

 than the stigma, ovate, acuminate, remote from the apex of the 

 wing; cubitus and anal nervure decolorous ; axillary areolet with- 

 out an additional transverse nervure. Terebra elongate. 



The small black species of this genus are parasites of 

 Curcidionidce and Lepidoptera, and may be taken plenti- 

 fully on umbellate flowers. Some of the males are not 

 easily distinguished from each other, as is notably the 

 case \i\ih. Jioricola and caudatus. A difficulty also occurs 

 in determining whether any particular insect belongs to 

 this genus or Calyptus. In Forster's synopsis the two 

 are widely separated under different rubrics, thus : — 



9. Segments 1 — 3 exarticnlate, connate . . Sigalphus. 

 11. Segments 1 — 3 articulated in the usual 



way . . . . . . • . • • Calyptus (Brachistes). 



But as this character is recondite, and, however true, 

 contrary to appearances, it may be useful to add the 

 distinction })ointcd out by Eeinhard. On inspecting the 

 under side of Sigalphus, the belly is found to be concave 

 from the base to the apex, its margins forming a sharply 

 defined edge, and not reliexed ; in Calyptus only the 1st 

 segment (and, in the J , the base of the 2d) is acutely 

 margined ; the edges of the rest are reflexed, so as
