scutellum united ; mesonotum with two complete furrows ; 

 scutellum triangular, with a punctured frenum ; meta- 

 thorax quadrate, with several longitudinal raised lines on

GoNiozus Forster. 



2. GONIOZUS MEXICANUS Sp. n. 



? . — Length 2 to 2.1 mm. Allied to G. cellaris Say^ 

 agreeing with it in colorational detail, and in having a small, 

 closed, triangular discoidal cell, but it is readily separated 

 from it, as well as G. -paUiditarsis Cam., by its smaller 

 size, much longer head, black mandibles and longer ab- 

 domen. 



The head in this species is nearly twice as long as wide,, 

 not narrowed behind the eyes, the space behind the eyes 

 being fully as long as the eye itself, while in G. cellaris 

 the head is only a little longer than wide, rounded behind 

 the eyes, the space being much shorter than the length 

 of the eye. 



The abdomen is as long as the head and thorax united 

 or slightly longer. The antennae, except the 7 apical 

 joints, as well as the tibi« and tarsi, are yellow or brown- 

 ish yellow, although the middle and posterior tibise are 

 sometimes dusky. 



Decribed from two $ specimens from Tepic. 



3. GONIOZUS TEPICENSIS sp. n. 



(5 . — Length 2.6 mm. Agrees in color and sculpture 

 with G. mexicanus, but the head is a little longer, fully 

 twice as long as wide, the space behind the eye being 

 twice as long as the eye, while the anterior wings have 

 no closed triangular discoidal cell, the basal vein having 

 only a slight stump of a vein present.
