Genus 9, PARAPOMPILUS. 
Micropteryx, St. Farg. Hym. iu. 396 (1845), nee Hiibn. 
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 wigs; 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 antennz imserted in deep fossu- 
lets on the anterior part of the face ; the prothorax longer than 
in the true Pompili, the metathorax elongate ; the wings mserted 
about the middle of the thorax, the anterior pair having one 
marginal and three submarginal cells. Abdomen sessile.
