GOEYTES. To 



smaller towards the apex ; covered (very closely and thickly on the apical segments) 

 with a grey pubescence ; all the segments above broadly banded with yellow ; the 

 second segment evidently longer than the first, becoming gradually dilated from the 

 base to the apex; pygidial area triangular, rugosely punctured; the first ventral 

 segment bearing large deep punctures, the other segments finely and irregularly punc- 

 tured. Legs pilose; the knees, the anterior and intermediate tarsi, their tibiae in 

 front, the posterior tarsi (except at the apex), the anterior and intermediate tibiae 

 behind (except a black line in the middle), the hinder tibiae at the base, and the 

 spurs, yellow, the hinder spurs inclining to rufous. The wings are clear hyaline ; the 

 cloud occupies the radial cellule (except a small space at the extreme base), the second 

 cubital cellule (except a narrow band on the lower side), the third cubital cellule 

 (except an oblique triangular part on the lower anterior side), and the space in the 

 discoidal cellule bounded by the recurrent nervures ; first and second cubital nervures 

 equally converging above, making the second cubital cellule above less than the space 

 bounded by the two recurrent nervures ; cubitus obsolete beyond the third cellule. 

 The mesosternal carina is broad, distinct; there is a moderately broad, semi-oblique, 

 deep furrow at the base of the metapleura. The tibial spines are almost obsolete. 



The affinities of this species are clearly with 6. hamatus, Handl., from Colorado. 

 The latter, however, differs from G.punctifrons in having the scape " short and broad "; 

 the basal joints of the flagellum oblique at the apex, the last joint incised, and the 

 apical five not so perceptibly thickened ; the ocelli separated by a greater distance 

 from the eyes than they are from one another (the opposite being the case in G. punc- 

 tifrons, in which they can hardly be said to form even a " stumpfwinkeligen Dreiecke," 

 the anterior being but a very short distance in front of the posterior ocelli) ; the wings 

 smoky (clear hyaline in G. punctifrons) ; the fascia on the pronotum interrupted 

 (continuous in G. punctifrons) ; the scutellum with two marks, and the flagellum 

 entirely, black. G. hamatus is also 2 millim. longer than G. punctifrons.

Antennae short, stout, yellow beneath, the flagellum thickened towards the apex ; the 

 yellow on the flagellum passing into rufous; the third joint nearly one quarter longer 

 than the fourth, the basal joint longer than the third. Head shining, rather densely, 

 but shortly pilose; almost impunctate, the clypeus with a row of punctures on the 

 projecting middle part ; front and vertex almost convex, the former slightly hollowed 

 over the antennae, without furrows or keels; eyes almost parallel ; the hinder ocelli
