2. Gorytes championi. 



Mgro-aeneus, nitidus, laevis, vix punctulatus ; scapo antennarum subtus, clypeo, basis mandibularum, margine 

 pronoti, scutello, metanoto, abdominis maculis duabus, tibiis tarsisque anterioribus, basi tibiarum posti- 

 carum medioque tarsorum posticis, albis ; alis hyalinis. Segmento mediali nitido, non striolato. 



Long. 6^- millim. 



Hob. Guatemala, San Geronimo (Champion). 



Basal joint of the antennae curved, a little longer than the third and fourth joints 

 united, the third and fourth subequal ; the flagellum thickened gradually to the apex, 

 the joints each a little longer than broad, brownish beneath. Head margined behind 

 the eyes, not much developed, and retreating ; front and vertex with short, the clypeus 

 densely covered with a longer, silvery-white pubescence ; palpi white ; eyes large, 

 strongly faceted, reaching to the base of the mandibles, converging beneath ; hinder 

 ocelli separated from each other by nearly twice the distance they are from the eyes ; 

 a narrow furrow runs from the ocelli to the antennae, which are inserted considerably 

 above the base of the clypeus ; the latter is convex, broadly rounded at the apex. 

 Thorax shining, rather closely-covered with whitish pubescence ; the median segment 

 with long soft white hair ; median segment impunctate ; the dorsal area clearly 

 limited, but neither punctured nor striolated ; mesopleurse punctured ; the mesosternal 

 furrow obsolete. Abdomen shining, impunctate, a little longer than the thorax ; the 

 petiole longer than the second segment, the apical half widely dilated, beneath obscure 

 brownish-white; the second segment with a white line on either side above; apical 

 segment short, broad, rather strongly punctured. Legs densely covered with white 

 pile ; the tips of the intermediate tarsi blackish ; the hind tarsi black, except the 

 greater part of joints 2 and 3 ; tibiae sparsely spined. 



G. championi differs from G. bipunctatus and its allies in having the median segment 

 not striolated at the base and not punctured. In G. championi the head and thorax 

 (especially the mesonotum) have a much more violaceous tint than the abdomen ; the 

 second cubital cellule is, at the bottom, shorter than the third ; the first recurrent 

 nervure is received before the transverse cubital, the second is interstitial. 



ii. Median nervure of the hind wing received beyond the posterior transverse nervure, 

 or interstitial ; the recurrent nervures not interstitial. 



A. Eyes not converging beneath ; median segment usually punctured, its base with a 



more or less triangular striolated area.
