PTEROMALIDAE OF N.W. EUROPE 87 



hind margin of basal tergite entire. Funicular segments of antenna less 

 transverse than in Brachyelatus . . CHRYSOMALLA Forster (p. 91) 



Fore wing with marginal vein with only short fine hairs along its front edge ; 

 postmarginal vein distinctly longer than the stigmal vein ; wing hyaline. 

 Pronotal collar not margined. Axillae not approximated, the base of the 

 scutellum therefore broad. Gaster with second tergite not longer than the 

 third ; hind margin of basal tergite slightly incised medially. Funicular 

 segments of antenna strongly transverse, those of the female about twice as 

 broad as long ; the middle segments in the male about three times as broad 

 as long BRA CHYELA TVS Hoffer & Nowicky (p. 92)

Key to European Species 



t Anterior margin of pronotal collar with two teeth. Gastral petiole, dorsally, 



with five longitudinal carinae (median, two submedian, two lateral). 

 Thorax shiny and nearly smooth. Body violet-black dentatus (Boucek) (p. 88) 

 Anterior margin of pronotal collar (Text-fig. 53) without teeth. Gastral petiole 

 with three longitudinal carinae (median, two lateral). Thorax distinctly 

 sculptured, green to blue, or partly copper to bronze .... 2 



2 (1) Whole surface of pronotal collar, mesoscutum, and scutellum with a coarse 

 honeycomb sculpture formed of large coalescent piliferous punctures, rela- 

 tively dull. 



Thorax blue to blue-green, with the pronotal collar green to golden or 

 copper ; lateral angles of pronotal collar nearly rectangular. Last segment 

 of antennal funicle in female about twice as broad as long. Large species, 

 3 to 4-5 mm. ...... splendidulus (Spinola) (p. 88) 



Thorax with at least the disc of the scutellum devoid of coarse punctures ; at 

 least some parts of the pronotal collar and mesoscutum with their piliferous 

 punctures either small or, if large, then not coalescent ; often the whole 

 thorax has relatively finer sculpture, which is sometimes partly composed 

 of strigosity ........... 3
