Genus 9. PARAPOMPILUS. 



Micropteryx, St. Farg. Hym. iii. 396 (1845), nee Hubn. 



The name Micropteryx having been used not only for a genus 

 of Lepidoptera, but also for one of Fishes, a new one has been 

 proposed. The species of which this genus is composed at pre- 

 sent, have, with one exception, abbreviated wings; this cha- 

 racter, however, must be regarded as only of specific value. The 

 genus is characterized by having the head compressed, the face 

 forming an oblique plane, the antennae inserted in deep fossu- 

 lets on the anterior part of the face ; the prothorax longer than 

 in the true Pompili, the metathorax elongate ; the wings inserted 

 about the middle of the thorax, the anterior pair having one 

 marginal and three submarginal cells. Abdomen sessile.
