COTHONASPIS.— BALNA. 73 



Foerster, many of them being founded on very slight characters. The species are very 

 numerous in the northern parts of Europe (where alone they have been properly 

 studied) ; but few have been recorded from America, and none hitherto from South or 

 Central America. 



COTHONASPIS. 



Cothonaspis, Hartig, Germ. Zeits. Ent. i. p. 201 ; Foerster, Verh. pr. Rheinl. 1869, p. 347. 

 No species of this genus have been previously recorded from America. 



1. Cothonaspis allotriiformis. 



Rufa, pe&ibus flavis, yertice lseta, mesonoto antennarumque apice nigro-piceis ; antennis corporis fere longitu- 

 dine, elava 5-articnlata, articulo tertio longiore quam quartus, scutelli fovea sat magna, ovata ; alis hyalinis, 

 longe ciliatis, cellula radiali elongata. 



Long. 1-2 millim. 



Hab. Mexico, Cordova {Salle). 



The antennae are nearly as long as the body; the third joint is longer than the 

 fourth ; the five apical form a club ; they are covered sparsely with microscopic hairs. 

 The cup on the scutellum is not so hollow as in the typical species of the genus ; the 

 wings are covered at the apex with long hair ; the radial cellule is closed. 



Fam. PIGITID5J. 



The Figitidae of the older authors have been split up into three groups — the Ana- 

 charina, Onychiina, and Figitina. No species of the first have been recorded from our 

 district, but one of the genera here described is intermediate between it and the second. 

 If these divisions are to be accepted, Leiopteron would require one for itself; but we 

 know so little about the American species that any attempt at their classification must 

 be regarded with distrust at present. 



BALNA. 



Antennae 13-jointed, filiform ; the joints of the flagellum longer than broad ; the 

 third joint longer than the fourth ; the rest becoming gradually shorter, but scarcely 

 thicker towards the apex. Cheeks and temples margined. Prothorax with the 

 margin distinctly ridged. Mesonotum with two wide and deep sutures, the centre 

 raised into a blunt ridge a little before the middle. A single fovea in front of scutel- 

 lum, which is produced at the apex into a blunt, short, thick spine. Thorax smooth, 

 shining, impunctate. Eadial cellule longer than wide, closed before and behind and 

 without a bounding nervure along the costa. Cubital nervure obsolete. 



This genus comes nearest to Aspicera, Dbm., but diners in having the thorax smooth, 

 shining, the scutellum not produced into a long, sharp spine, and with only a single 

 fovea at the base, while the radial cellule is completely closed before and behind.
