PTEROMALIDAE OF N.W. EUROPE 817 



strong, especially posteriorly. Fore wings similar to those of female dynastes, but with the 

 apical margin ciliate over at least its hinder half. 



Gaster ovate, slightly shorter than head plus thorax, 1-5-1-6 times as long as broad ; its 

 apex pointed but not acutely so, the sides of the last tergite meeting at an angle of about 90 . 



o*. Differs from the female as follows: 



Head, thorax, and coxae bright green ; gaster greenish bronze, with a yellowish transverse 

 band before the middle ; antennal scape, tegulae, and remaining parts of legs, bright yellow ; 

 rest of antenna orange-yellow with the clava slightly darker ; mandibles yellowish ; wing- 

 veins yellowish. Length i-8 mm. 



Antenna (Text-fig. 674) with pedicellus slightly shorter, hardly twice as long as broad ; 

 funicle more slender, hardly stouter than the pedicellus. 



Thorax less squat, 1-5-1-6 times as long as broad, with the mesoscutum rather less than twice 

 as broad as long ; propodeum slightly longer, its median area less transverse. 



Gaster oval, about as long and as broad as the thorax. 



Holotype $. England : West Kent, Belgebury [? Beclgebury] Park, reared 

 from cocoon of Cionus sp. (Col., Curculionidae) on Scrophularia sp., collected on 

 4.viii.i935, the parasites emerging 11.viii.1935 (0. W. Richards), in BM(NH).

D. cionobius is easily distinguished, in both sexes, from dynastes (Forster) by the 

 shape of the head as seen from above, and by the larger second anellus of the antenna. 



In female dynastes the head in dorsal view (Text-fig. 676) is slightly less transverse 

 than in cionobius ; the temples are relatively longer, about half as long as the eyes, 

 and are not acutely pointed posteriorly ; POL is about equal to OOL. The eyes 

 are rather longer (length : breadth nearly 1-7:1) and their inner orbits are virtually 

 parallel. The pedicellus is slightly longer, in dorsal view a little more than twice as 

 long as broad ; the second anellus is large, subquadrate, twice as long as the first 

 anellus and about two thirds as long as the first funicular segment. The gaster is 

 relatively longer (as long as, or very slightly longer than, head plus thorax) and is 

 more sharply pointed apically, the sides of the last tergite meeting at a slightly 

 acute angle. Slight differences in the thoracic structure of of the two species have 

 already been mentioned. The head and thorax of female dynastes tend to be a 

 brighter green than in female cionobius. 



In male dynastes the head is shaped much as in the female (cf. Text-fig. 676) 

 though with the temples very slightly acute, but not so distinctly so as in cionobius. 

 The eyes are relatively longer than in male cionobius, and have their inner orbits 

 virtually parallel. The second anellus is only slightly transverse, and is a half to 

 two thirds as long as the first funicular segment.
