14 HYMENOPTEEA. 



J 



18. Ammophila dejecta. 



Nigra, abdominis medio late ferrugineo ; dense fulvo-cinereo-pilosa ; facie aureo-pilosa ; clypeo fere truneato ; 



alis fere hyalinis, apice fumatis. 

 Long. 17-18 millim. 



Hob. Mexico, Northern Sonora (Morrison). 



Head wider than the mesothorax, indistinctly shagreened, covered with moderately 

 large punctures ; frontal furrow indistinct; clypeus bent inwardly at the apex, giving 

 it the appearance of being incised. Posterior ocelli separated from each other by a 

 less distance than they are from the eyes, and from the front ocellus by half this space. 

 Third antennal joint one quarter longer than the fourth. Pro thorax with a shallow 

 oblique furrow. Thorax closely punctured ; postscutellum rugose ; metanotum striated, 

 running into reticulations, the apex strongly punctured. An indistinct furrow runs 

 down from the tegulae. The hair on the thorax is long and dense; there is an 

 oblique silvery stripe along the mesopleurae; the metapleurae bear silvery hair, and 

 there is a tuft of cinereous pile on either side of the metanotum. The basal joint of 

 the petiole beneath, the whole of the second joint, and the first and second segments 

 (except a black line above) are ferruginous ; the apical segments are scarcely pilose. 

 Coxae with rather long silvery-white hair ; the rest of the legs with a short hoary pile ; 

 spines fuscous-black ; claws ferruginous at the tips. Second cubital cellule at the top 

 one fourth longer than the third and shorter than the space bounded by the recurrent 

 nervures ; third cubital cellule at the top one third shorter than at the bottom ; second 

 transverse cubital nervure slightly oblique, straight; first recurrent nervure received 

 before the middle of the cellule. 



n 19. Ammophila cora, (Tab. I. figg. 18; 18 a, s .) 



Nigra, cinereo-hirta, apice petioli supra abdominisque segmento 1° ferrugineis ; clypeo exciso ; mesonoto 



punctato ; scutello longitudinaliter striato ; metanoto transverse striato ; alis fuscis. <$ . 

 Long. 18 millim. 



Hab. Guatemala, San Geronimo (Champion). 



Head shining ; the face and clypeus sparsely punctured ; the vertex with very few 

 punctures ; sparsely covered with long whitish hairs and with no pile ; apex of the 

 clypeus depressed, with a distinct margin and broadly, but not deeply, incised. Eyes 

 converging on the lower side. Front shallowly depressed in the centre. Third 

 antennal joint fully one quarter longer than the fourth. Prothorax with a wide trans- 

 verse and a narrower oblique furrow laterally. Thorax shining, covered with long 

 griseous hairs ; the pleurae, pro- and mesonotum punctured ; scutellum with some coarse 

 longitudinal striations ; the metanotum coarsely and closely transversely striated. Legs 

 covered with a close hoary pile ; the bristles and hind calcaria pale ; tips of the 

 claws ferruginous. Top of the second cubital cellule as long as the distance between 

 the recurrent nervures and a little shorter than the third cellule at the top ; the first
