 yellow and the lateral spots round and whitish, sometimes the apical bauds are 

 narrow and the lateral spots wanting except on second segment, sometimes the 

 first segment has no lateral spot. Length .85 inch. 



Eight specimens. (Belfrage ; Boll ; Heiligbrodt.)

% 9- — Uniformly dull ferruginous, subsericeous ; 9 clypeus, sides of face, 

 transverse line above antennae, posterior orbits broader beneath and mandibles, 

 yellow, clypeus subconvex, and sparsely punctured; % clypeus, face as far up

 sometimes a lateral spot, spot beneath tegulae, space between four anterior 

 coxae in % , tegulae, line on outer side of all the coxae of 9 > coxae beneath of % , 

 knees and four anterior tibiae and tarsi beneath of 9 an d narrow apical mar- 

 gin of abdominal segments, more or less sinuate anteriorly and sometimes a 

 spot on each side of first and second segments, all lemon-yellow; mesothorax

 versely wrinkled; wings fuscous, or fusco-hyaline, yellowish along costa, sub-

Seven specimens. (Belfrage.) Smaller, less robust and darker in 

 color than texana, to which it is closely allied. The ornamentation of 

 the abdomen is, however, very different.
