PTEROMALIDAE OF N.W. EUROPE 221 



Chrysolampus phyllochlorus Forster, 1841 : 37, $. 



Stictomischus pleuralis Thomson, 1876a : 236, $. 



Stictomischus gibbus (Walker) ; Delucchi, 1955 : 77, 81-83, 6* ?• 



Type material. Miscogaster gibba Walker. One female, LECTOTYPE (but 

 possibly holotype), bearing a Waterhouse label. 



Stictomischus pleuralis Thomson. Syntypes, 4 specimens. LECTOTYPE, a female 

 labelled " Sthm " [Stockholm] and " pleuralis Ths ". 



Chrysolampus sublaevis Forster and Ch. phyllochlorus Forster were placed in 

 synonymy with gibbus (Walker) by Delucchi (1955 : 81). I have not seen the types 

 of Forster's species but accept Delucchi's opinion. 



Britain, Sweden ; rather uncommon. 



Biology. Recorded from Sweden as a parasite of Amaurosoma flavipes (Fin.) 

 and A. armillatum Zett. (Dipt., Scatophagidae) (Secretariat, etc., 1957 : 321, 330). 

 Otten (1942 : 226) recorded Stitomischus pleuralis Thomson from Germany as a 

 parasite of Chylizisoma vittata Mg. on Lister a ovata L., but I agree with Delucchi 

 who considered (1955 : 83) that Otten's determination of the parasite was probably 

 wrong. Imagines June-July. 



Stictomischus tumidus (Walker) 



Miscogaster tumida Walker, 1833 : 463, $. 



Stictomischus rugicollis Thomson, 1876a : 236, o* ?, syn. n. [nee Delucchi, 1955]. 



Stictomischus tumidus (Walker) Delucchi, 1955 : 78, 84-85, <J $. 



Type material. Miscogaster tumida Walker. A male and a female stand under 

 this name. The female is designated LECTOTYPE ; it bears a Waterhouse label, 

 also one in C. Ferriere's handwriting " Type CF ". 



Stictomischus rugicollis Thomson. Syntypes, 8 specimens. The only type 

 localities which Thomson specifically mentions are Tvedora, Bastad, and Lund. A 

 female labelled " Ld 8/6 " and " L-d " [Lund] is designated LECTOTYPE. Delucchi 

 (1955 : 88) treated rugicollis as a distinct species. However, the only specimen in 

 Thomson's collection which agrees with Delucchi's description of supposed rugicollis 

 is the first in the series ; it was taken at Ringsjo and therefore cannot be the type, 

 moreover it disagrees with Thomson's description, which Delucchi can hardly have 

 consulted. Delucchi's supposed rugicollis is evidently very near, and might be the 

 same as, groschkei Del. 



Britain, Sweden, Germany, Austria, Czechoslovakia. Rather uncommon ; 

 in England I have swept it from the foliage of Quercus robur and Q. petraea. 

 Biology. Unknown. Imagines captured in May, July and August.
