PTEROMALIDAE OF N.W. EUROPE 413 



- Fore wing with a fuscous spot below the basal part of the marginal vein ; 



stigma subcircular or short-oval ; stigmal vein forming a rather less acute 

 angle with the postmarginal vein. Antennal flagellum virtually cylindrical. 

 Scutellum, in profile, appearing slightly convex guttatus (Ratzeburg) (p. 415) 



(Males) 



1 Fore wing without a speculum or with at most a very narrow bare strip ; the 



upper surface of the wing, not counting the costal cell, otherwise entirely 

 pilose ; lower surface of costal cell with two or more rows of hairs even 

 in its proximal half ; usually a large fuscous blotch below but touching the 

 stigma, often another spot on the disc of the wing below the parastigma. 

 Antenna with proximal segments of funicle, in larger specimens, longer than 

 broad ........ tutela (Walker) (p. 413) 



- Fore wing with a moderate-sized or large speculum ; basal cell often sparsely 



pilose ; lower surface of costal cell with only one row of hairs in its proximal 

 half ; wing immaculate .... brevicornis Thomson (p. 414) 



and guttatus (Ratzeburg) (p. 415) 



I am not able at present to give good characters for distinguishing the males of 

 brevicornis and guttatus.

Type material. Cheiropachus tutela Walker. Six specimens stand under this 

 name but the series is very mixed and clearly the types of some other species have 

 been misplaced here. LECTOTYPE, a female bearing a Waterhouse label 

 " Cheiropachus Tutela Walker " and my lectotype label. 



Cleonymus maculifer Forster. Types not seen (presumably in Naturhistorisches 

 Museum, Vienna). Ferriere (1948 : 520) stated that he had seen a specimen of 

 maculifer from Forster 's collection and found it to be the same as Rhopalicus tutela. 



Pteromalus suspensus Ratzeburg. The types of this and the following Ratzeburg 

 species are presumably destroyed. Kurdjumov (1913 : 10) transferred stispensus to 

 Rhopalicus, at the same time synonymizing with it Ratzeburg's species spinolae 

 {^multicolor) , lunula, and aemulus. This synonymy has been generally accepted. 

 In the case of suspensus Ratzeburg must have had a mixed series because he stated 

 (1844a : 189) that his original specimens had been obtained both from " Kegelform- 

 igen Gallen der Buchenblatter [Cecidomyia fagi) " and from the larvae of Bostrichus
