80 STRATIOMYID.E 



CLITELLARINiE. 



Abdomen short, with only five or six obvious segments. Lower cross- 

 vein absent, so that the upper branch of the postical vein forms for a 

 short distance the lower margin of the discal cell; discal cell emitting

three veinlets irrespective of the upper branch of the postical vein ; cubital 

 fork short or absent. Tibise without any spurs. 



Anteniije with or without a short apical or subapical arista, or with a short style, 

 almost homologously jointed or with the annulated third joint obviously oval. 



Thorax squarely Ixiilt. Scutellum with two marginal spines {Oxycera, etc.) or 

 unarmed (JVeviotelus, etc.). 



Abdomen short and broad, often arched, oval or conical, and sometimes even 

 broader than long, but usually a little longer than broad, with only five or six 

 apparent segments. 



Legs stout, moderate in length ; tibiiB without any spurs. 



Wings with three incomplete or faint veinlets issuing from the discal cell, besides 

 the upper branch of the postical vein which appears to issue from the discal cell 

 l)ecause the small cross-vein is absent, and therefore the upper branch of the 

 postical vein forms for a varying distance the lower margin of the discal cell ; live 

 wide open posterior cells (if the subapical and postical cells be included). AVing- 

 membrane minutely and densely pubescent in all the European genera except 

 Xemotel'us, but in that genus practically Imre ; ribbed in O.n/cera, rii)i)led in 

 Ephijrinwn and Las/opa, but with only slight folds in Femotelm, Clitellaria, and 

 FyciwmaUa. AluUe large folded against the scutellum when at rest. Squamte (alar) 

 moderately small, and with a short fringe ; thoracal pair either absent, or moderately 

 developed, and when develoi)ed with a long delicate fringe and with both the dorsal 

 and ventral surfaces pubescent. 



The essential characters of the Clitellarincv lie in the small number 

 of abdominal segments, whereby they are distinguished from the Berince 

 and Sylomyina: ; the three veinlets from the discal cell, irrespective of the 

 upper branch of the postical vein, whereby they are distinguished from 

 the rachygastrinw and some Bei^incv and Stratioiayina:. ; the absence of the 

 lower cross-vein, whereby they are distinguished from the Saryinm and 

 Stratiomyincc. The boundary line between them and the Stratiomyince is 

 very slight at times, as (in Bphippmm for example) the upper branch of
