 tex, 2 four and two-third times as long as 1 ; 3 as in key, sometimes suf- 

 fused with pink, nearly one-third as long as 2; 4 pale, dusky towards tip, 

 one-tenth shorter than 3. Beak reaching tips of middle coxa?. Hind

 shorter than eye; 2 reddish-yellow, feebly gradually thickened toward tip, 

 three and a half times longer than 1. Head strongly inclined, narrower 

 than basal margin of pronotum. Beak reaching middle coxa?. Pronotum 

 about one-half shorter than wide at base, hind margin truncate, one-half 

 wider than front one; sides rather strongly concave. Scutellum mod- 

 erately convex. Elytra slightly constricted, surpassing abdomen. Length,
