described by Kamijo (i960 : 30). According to the description, the female of elongatus has the 

 malar space slightly more than one quarter the length of an eye, whereas in lamprosomus it is 

 virtually one third ; the stigma of the fore wing in elongatus, according to Kamijo's figure (i960, 

 fig. 3B) is somewhat smaller than that of lamprosomus, being separated by about i-8 times its 

 height from the costal edge of the wing (in lamprosomus by only about 1-5 times its height). 

 In some other small details lamprosomus does not quite fit the description of elongatus and there- 

 fore I presume it to be a valid species. I have not had an opportunity of examining the type 

 of elongatus.

Type material. Miscogaster obscura Walker. Of the specimens standing under 

 this name only 5 appear to be original material. One of these, a female bearing a 

 Waterhouse label, is designated LECTOTYPE. 



Miscogaster obscuripennis Walker. Syntypes, 3 specimens. LECTOTYPE, a 

 female bearing a Waterhouse label, also one in C. Ferriere's handwriting " Type 

 CF". 



Miscogaster chrysochlora Walker. Syntypes, 3 specimens. LECTOTYPE, the 

 first, a female with Waterhouse label, also one in C. Ferriere's handwriting " Type 

 CF". 



Lamprotatus mallius Walker. One male, LECTOTYPE, bearing a Waterhouse 

 label. 



I have not seen the types of Chrysolampus splendens Forster and Ch. subquadratus 

 Forster but accept Delucchi's synonymy (Delucchi, 1955 : 89). 



Britain, Ireland, France, Sweden, Germany, Switzerland, Austria,

Biology. Cameron (1935 : 299) recorded having reared obscurus from puparia of 

 Pegohylemyia seneciella Meade (Dipt., Anthomyiidae) in capitula of Senecio jacobaea 

 L. in Britain ; the specimens have not been seen, and confirmation of the record is 

 desirable. Imagines appear June- July.
