Britain : local, in woods, particularly in shady areas. 

 Biology. Unknown. Imagines Apr.-Aug. 



Cricellius gracilentus (Boucek) 



Dibrachella gracilenta Boucek, 1954 : 55~57- 6* ?• 

 Cricellius gracilentus Boucek, 1958a : 401. 



Type material. Holotype $, Czechoslovakia, Bohemia, neighbourhood of Velky 

 Vfestov, in the second half of August, 1953 {Boucek), in Narodni Museum, Prague 

 (Cat. no. 3005). 



Czechoslovakia. 



Biology. Unknown. Imagines July-Aug. 



I have seen a number of specimens of gracilentus (including the holotype) and have 

 checked the differences mentioned in my key below, between it and gracilis (Walker), 

 by measurements. I feel sure that they are distinct, although -close, species. 



Cricellius repandus sp. n. 



(Text-figs. 443, 446) 



$. Head and dorsum of thorax dull green, the occipital surface more bluish, the scutellum 

 slightly tinged with bronze ; sides and venter of thorax dark bluish. Gaster bronze, with 

 some greenish reflections, especially on the basal tergite. Antennae fuscous. Coxae dark 

 blue ; trochanters dark, trochantelli paler ; femora black, narrowly testaceous at apex ; 

 tibiae mainly fuscous, their bases and tips testaceous ; tarsi testaceous, their tips brown, the 

 fore tarsi mainly brown. Tegulae fuscous ; wings subhyaline, venation brown to fuscous. 

 Length 2 to 2-1 mm. 



Head in dorsal view (Text-fig. 443) 2-2 to 2-25 times as broad as long (and 1-2 to 1-25 times as 

 broad as mesoscutum) ; temples converging strongly, barely one quarter as long as eyes ; 

 posterior ocelli separated by about 1-5 times their major diameter from the eyes. Eyes sepa- 

 rated by about 1-5 times their length. Malar space nearly three fifths the length of an eye. 

 Clypeus rather dull, mainly reticulate with the sculpture slightly raised above the general 

 surface, its anterior margin slightly curved forwards. Head somewhat shiny, finely reticulate. 

 Antenna (Text-fig. 446) with scape reaching to about middle of median ocellus ; combined length 

 of pedicellus and flagellum barely equal to breadth of head ; pedicellus i-6 to i-8 times as long 

 as broad ; the three anelli together about as long as the first funicular segment, the first and 

 second anelli subequal in length and breadth, the third slightly longer and broader ; flagellum 

 clavate, funicle stout, proximally nearly 1-5 times as stout as the pedicellus ; funicular seg- 

 ments one to four quadrate or very slightly transverse, five slightly transverse ; clava 1 -6 to 1 -8 

 times as long as broad, somewhat longer than the combined length of the two preceding funicular 

 segments, obtuse apically, its first suture not oblique, the second very slightly so ; ventrally 

 there is a line of micropilosity extending along the whole of the third segment, and encroaching 

 very slightly on the second. Sensilla of funicle not very numerous, in one row on each segment. 



Thorax about i-6 times as long as broad. Pronotal collar with its sides converging slightly 

 forwards ; sharply margined in front, but the carina fine and not strongly raised. Mesoscutum 

 1 -4 to 1 -5 times as broad as long, moderately shiny, finely reticulate, more coarsely on the disc 

 posteriorly, the reticulation distinctly but not strongly raised above the general surface. Axillae 

 very finely reticulate, moderately shiny. Scutellum about as broad as long, hardly less shiny 

 than the mesoscutum, very finely reticulate ; base of scutellum relatively broad. 



Propodeum medially slightly more than half as long as the scutellum, finely and irregularly 

 reticulate. Fore wing with upper surface of costal cell bare, lower surface with one complete
