30. Pompilus Omiltemensis. (Tab. XI. figg. 18, head; 18 «, wing.) 

 Long. 9 millim. 



Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H Smith) ; Panama, Volcan de 

 Chiriqui 4000 to 6000 feet (Champion). 



Black, the whole body sparsely covered with long black hair ; the median segment 

 pruinose. Eyes curved ; the ocelli large, in a triangle, the hinder ones separated 

 from the eyes by a distinctly greater distance than they are from each other ; clypeus 

 projecting, broadly rounded, the middle part faintly incurved ; frontal furrow distinct, 

 especially over the antennae. Antennae slender, bearing a microscopic pile ; the third 

 joint distinctly longer than the fourth. Pro thorax shorter than the head ; the apex 

 bluntly angulated. Median segment indistinctly furrowed down the centre and with 

 a gradually rounded slope. Abdomen a little shorter than the head and thorax united, 

 subsessile ; the apex above and beneath with long hairs. Legs long, moderately slender ; 

 the tibial spines longish ; the long spur of the hind tibiae reaching a little beyond 

 the middle of the metatarsus ; claws with a sharp basal tooth. 



The male has the head and thorax covered with long hair, as in the female ; the 

 apex of the clypeus incised in the centre ; the antennse longer than the head and 

 thorax united, and densely covered with pile, their third and fourth joints subequal ; 

 the abdomen as long as the head and thorax united, and with a violet bloom ; the last 

 ventral segment raised and shining in the centre, this raised part being bordered by a 

 deep furrow on either side.

Numerous specimens of a Pompilus from the above-quoted Central- American localities 

 probably belong to this species. In the British Museum there is also an example of 

 it under this name from Mexico. The species varies in the colour of the body as regards 

 having blue, greenish, or purplish reflections, and it likewise varies in size. 



I give a fresh description from the specimens before me : — 



Head alutaceous, sparsely haired, behind concave ; the eyes slightly converging 

 beneath ; the hinder ocelli separated from the eyes by about the same distance that 

 they are from each other ; a furrow runs down to the antennse ; the clypeus is opaque,
