Sphecomorpha Rond., Annal. Soc. Entom. Fr., (2). VIII. 212. 

 (Sphiximorpha) (1850).

Head rather flattened, broader than the thorax with the face 

 almost straight in front, but descending below the eyes and some- 

 what produced at the front mouth-edge. Eyes touching in the 

 male, but well separated in the female. Antenna? elongate and 

 sometimes placed on a more or less long iJetiole or stalk ; the 

 first joint is long and slender but the second and third joints are 

 shorter, about equal in length and the two together are about as 

 long as the first joint ; these two joints form together an elongate 

 oval mass, and the third joint bears a terminal style. 



Thorax rather elongate, quadrangular, rather thinly rugose, 

 and always possessing yellow spots. Scutellum semicircular, more 

 or less yellow. 



Abdomen elongate, cylindrical, contracted, more or less wasp- 

 shaped at the base, and bearing yellow bands or markings. Legs 

 moderately strong with the femora somewhat thickened and the 

 tibia? sometimes subclavate. 



Wings with a distinctive and peculiar venation ; Radius 4 + 5 

 has a deep loop about the middle of cell R5 at the bottom of 

 which loop arises a veinlet descending about half way or less 

 across cell R5; radio-median cross-vein possesses the costal border 

 as far as the vena spuria darkened and also a darkened border 

 along Cubitus 2. 



The larva according to Dufour, who has described ami fiffu- 



red it (as well as the pupa) (Ann. Soc. Ent. France, 2 V., 19, PI. I, 



1'. 1-6. 1847) lives in the sap of diseased trees such as Elms 



(Ulmus). Schiner also states that he has bred an European species 



C. conopsoides( ?) from decaying poplars (Populus).
