PTEROMALIDAE OF N.W. EUROPE 71 



Masi (1928a : 57) remarked that his Eunotomyia festiva was probably only a 

 variety of Tomocera calif ornica. The holotype female oi festiva is in BM(NH) under 

 Type Hym. 5. 655 ; it is labelled " Percy Sladen Trust Exped. B.M. 1913-170 "; 

 " Eunotomyia festiva Masi $ " and pinned to a piece of cork on which is written 

 " Mahe, ' 08-09 Seychelles Exp." It appears to be very similar to calif ornica and 

 might even be the same. 



Cosmopolitan ; in Europe only in the south. It has been introduced into some 

 areas. Smith and Compere (1928 : 317) stated that it probably originated from 

 Australia and that it was probably introduced into the U.S.A. and Hawaii along 

 with the black scale. 



Biology. Parasitic on scale-insects, particularly Coccidae such as Saissetia and 

 Ceroplastes spp. ; rarely hyperparasitic through Encyrtid species. For a list of 

 hosts see Peck (1963 : 632). 



EUNOT US Walker 



Eunotus Walker, 1834 : 297. Type-species : E. cretaceus Walker, by monotypy. 

 Tritypus Ratzeburg, 1848 : 227. Type-species : T. areolatus Ratzeburg, by monotypy. 

 Megapelte Forster, 1856 : 63 [n. n. for Eunotus Walker, supposedly pre-occupied]. 

 Eunotus Walker ; Schmiedeknecht, 1909 : 304, 306. 

 Eunotus Walker ; Masi, 193 1 : 423-438. 

 Eunotus Walker ; Nikol'skaya, 1952 : 236. 

 Eunotus Walker ; Peck et al., 1964 : 31-32. 



The European species of Eunotus are badly in need of revision. The writer has 

 not seen the types of the majority of them and so is not in a position to prepare a 

 revision. At present the most useful paper for identification purposes is that of 

 Masi (1931). 



Provisional key to some European species 

 (Females) 



The following key is adapted from that of Masi (1931 : 424). Although some of the characters 

 used by him will undoubtedly continue to be useful, additional ones should be sought for more 

 accurate delimitation of some of the species. 



1 Antennae with five funicular segments, the first segment sometimes smaller 



than the second but always quite distinct (sgen. Eunotus Walker) . . 2 



- Antennae with four funicular segments (sgen. Eunotellus Masi) ... 5 



2 (1) Basal tergite of gaster (Text-fig. 54) mainly to entirely alutaceous. Marginal 



vein of fore wing 1-7 to i-8 times as long as the stigmal vein ; hind margin 

 of wing nearly straight in its distal part, just before the apex of the wing 



cretaceus Walker (p. 72) 



- Basal tergite of gaster entirely, or almost entirely, smooth. Marginal vein of 



fore wing sometimes relatively shorter ; hind margin of wing more evenly 

 curved in its distal part ......... 3 



3 (2) Fore wing with marginal vein only slightly longer than the stigmal vein. Pro- 



podeum with the raised crest formed by the anterior part of the median 

 carina, when seen in profile, jutting out somewhat beyond the level of the 

 tip of the scutellum. Antenna with funicle (except proximally) testaceous, 

 clava mainly fuscous to black .... nigriclavis Forster (p. 73)
