S . Closely resembles some forms of L. analis, Fabr., but differs 

 in having the apical half of the abdomen fulvous with fulvous 

 pubescence, not ferruginous, in the head, thorax, and abdomen, 

 especially the last, being much more closely punctured, and being 

 on the whole, sex for sex, a stouter, broader insect.

Family POMPILID^. 



Possorial and predatorial wasps of very varying size, containing 

 some very small species as well as some of the largest forms 

 among the Hymenoptera. 



Head more or less lenticular in shape. Prothorax of variable 

 size and length, the pronotum, however, always reaching back to 

 the base of the wings. Wings generally long and ample, in one 

 genus only {Parapom-pilus*) extraordinarily short ; fore wing with 

 one radial and txvo or tliree complete cubital cells f. When t\\ o 

 cubital cells only are present, the 2ud receives both the recurrent 

 nervures ; when there are three cubital cells, the 2nd receives the 

 1st, and the 3rd the 2nd recurrent nervure. Legs long, reaching 

 well beyond the apex of the abdomen ; armature of the legs 

 variable, dependent on fimction. Abdomen pseudosessile, never 

 actually petiolate as in some of the Sphegidce., but the basal seg- 

 ment of the abdomen at its attachment to the median segment is 

 often attenuated. 



The difference between the sexes is well marked, sometimes it is 

 very striking. The males are, as a rule, smaller, aud more 

 slenderly built ; the antennae are porrect ; in the females these 

 organs, after death, are convolute at apex J. The apical three 

 abdominal segments in the male are essentially different from those 

 in the female. If the median segment is not included, the female 

 has six, the male seven visible abdominal segments. 



* Not known to occur in India. 



t In the genus Ceropales, by the extension of the cubital nervure to the 

 margin of the wing, a 4th complete cubital cell is formed, but the character is 

 not constant. 



\ Except in the genus Cer&pales, the females of which have porrect antennce.
