ASTATA. '67 



Antennae as long as the thorax ; the base sparsely pilose ; the third joint curved, 

 longer than the fourth. Head shining, somewhat strongly punctured ; the face and 

 front bearing rather long pale fuscous hair; the vertex sparsely and microscopically 

 pilose. Mandibles with some large irregular punctures towards the apex, and hollowed 

 in the centre there, and, except at the extreme tip, reddish. Clypeus rounded, the 

 apex margined ; the centre slightly incised ; the base depressed ; the sides semiopaque, 

 closely punctured ; the central part shining, sparsely covered with large punctures. 

 Prothorax closely punctured ; mesonotum shining, the sides punctured, the centre 

 almost impunctate. Seutellum strongly punctured round the edges, the centre only 

 sparsely punctate. Mesopleurae rugosely reticulated ; sternum strongly punctured ; 

 metapleurae obliquely striolated ; median segment rugosely reticulated, the apex rugose. 

 Abdomen shining, almost impunctate. Pygidial area opaque, finely rugose, almost 

 glabrous, margined at the sides ; a few stout bristles issue from the edges near the apex. 

 Femora bearing black hair, the tibiae and tarsi stiffly spinose ; the apices of the tarsi 

 (especially of the anterior pair) reddish. Eadial cellule scarcely so long as the second 

 and third cubital cellules united ; the radial nervure at its apex turned sharply back- 

 wards towards the stigma ; the second cubital cellule one half longer than the third, 

 and scarcely so long as the first at the bottom, at the top shorter than the space 

 bounded by the recurrent nervures. Tegulae brownish. 



v 4. Astata tinctipennis. 



Nigra, longe albo-hirta ; capite (vertice excepto) punctato ; pleuris rugoso-punctatis ; segmento mediali 



reticulato ; mesonoto cum scutello nitidis, lsevis ; alis hyalinis, apice fusco-tincfcis. § . 

 Long. 9 millim. 



Hab. Mexico, Presidio (Forrer). 



Antennae as long as the thorax, bearing a microscopic down ; the third joint nearly 

 one fourth longer than the following one. Face, front, cheeks, and occiput bearing 

 long cinereous hair, and strongly punctured to the ocelli; the vertex behind them 

 being shining, and with only a few scattered punctures. Clypeus rounded, the apex 

 projecting, only slightly shining in the middle, the sides more opaque, and closely 

 punctured. Mesonotum and seutellum shining, punctured, the former posteriorly and 

 the seutellum but sparsely so. Pleurae and sternum rugosely punctured; median 

 segment reticulated, the apex with an oblique slope, rugose. Except on the seutellum 

 and mesonotum, the thorax is covered with moderately long white hair. Abdomen 

 not much longer than the mesothorax, shining, impunctate. Pygidial area closely- 

 punctured ; the sides raised and bearing throughout a fringe of stout bristles ; the 

 centre is for the greater part reddish. Femora sparsely haired ; tibiae and tarsi thickly 

 spinose. Radial cellule shorter than the second and third cubital cellules united, the 

 apex bent sharply backwards ; the third cubital cellule at the bottom is as long as the 

 space bounded by the first recurrent nervure and the second transverse cubital nervure ;
