trie sides; there is a black longitudinal furrow on the mesopleura. Median segment 

 with a rounded slope to the apex, which has an oblique one ; down the middle it is 

 deeply furrowed, and at the sides at the base and apex there is a blunt tubercle. Apex 

 of the abdomen with some longish hairs. The legs are long, especially the tarsi, which 

 are twice the length of the tibiae ; the anterior tarsi with long curved spines and ciliated 

 beneath, the hinder tarsi with short spines ; the tibial spines short, stout ; the long 

 spur of the hinder tibiae not reaching the middle of the metatarsus. The basal nervure 

 is interstitial, as is also the anal nervure in the hind wings. 



In both sexes the third antenna! joint is longer than the fourth ; in the male the 

 apex of the clypeus is more transverse than it is in the female. 



Apparently a common species in Yucatan.

Pompilus marcidus, Smith, Journ. Ent. i. p. 395 1 j Cresson, Trans. Am. Ent. Soc. i. p. 110 2 . 

 Hab. Mexico, Orizaba (Mus. Brit. 1 ). 



A specimen from Bugaba may belong to this species ; but Smith's description is too 

 vague to enable me to speak with certainty, the description dealing only with colour. 

 As regards colour, the only difference is that P. marcidus has the apex of the four 

 hinder tarsi black and the femora red, while in the Bugaba specimen the hinder coxae 

 and femora are for the greater part black, and the tarsi without black. The Bugaba 

 example agrees with P. pygidialis in having the fore claws cleft, and also in the form of 

 the head, i. e. the eyes converge more than usual at -the top. It is, however, evidently 

 distinct, for it has the third cubital cellule at the top not much more than half the 

 length of the bottom, it being also shorter than the second ; the long tibial spur on 

 the fore legs does not equal the metatarsus in length, it being distinctly shorter; 

 the spur of the middle tibiae is not much more than half, that of the hinder tibiae 

 not two-thirds, the length of the metatarsus. No mention either is made of P. pygi- 

 dialis having the seven apical joints of the antennae black, nor of any black colour on 

 the hind legs. Undoubtedly, however, the two are very closely related. There are 

 only three spines on the fore metatarsus ; and the nervure in the hind wings is received 

 beyond the cubital. „
