[December 
hind margin distinctly bisinuate ; surface closely and rather 
coarsely punctate, alutaceous, pubescent, sparsely covered 
with thick setae. Visible part of the scutellum forming a 
strongly transverse triangle. Elytra with broadly explanate 
margins; rather close, coarse, obsolete punctures; aluta- 
ceous ; finely pubescent ; each elytron with about seven rows 
of thick setae. Beneath coarsely punctate, sparsely and fine- 
ly pubescent. Length 5. 3-6. 7 mm., width 3. 1-4.1 mm. 
Holotype female, allotype male, and 2 paratypes from 
Arizona in the Leconte collection, Museum Comp. Zool. ; 
14 paratypes from 6-7000 ft., Stratton, S. Catalina Mts., 
July 27, 1917, W. M. Wheeler collector; 1 paratype, Pata- 
gonia Mts., Arizona, July 20-Aug. 6, 1930 in the Mus. 
Comp. Zool. In the U.S.N.M. 25 paratypes from Oracle, 
Arizona, October 7 ; 4 paratypes from Palmerlee, Arizona ; 
7 paratypes from the Santa Rita Mts. and Fort Grant, 
Arizona. In the University of Kansas collection 4 paratypes 
from the Chiricahua and Huachuca Mts., July-Aug. One 
paratype each from Prescott, Arizona, Chisos Mts. and 
Alpine, Texas, July, in the collection of H. C. Fall. Also 2 
paratypes from the Huachuca Mts., 2 paratypes from 
Oracle, June 7, and 3 paratypes from Globe, Arizona in the 
collection of the author. 
This species varies in outline and in color. In the pale 
specimens the maculation is most evident, whereas in those 
that are piceous the maculation is not discernible. The 
species is distinctive in the prominent lobes over the inser- 
tion of the antennae, transverse scutellum, and the unusual 
covering of thick setae. It is apparently related to undulata; 
in fact Mr. Fall has specimens of undulata from Texas which 
approach falli in the maculation, setae and lobes over the 
insertion of the antennae. But in falli the scutellum is more 
transverse, punctures beneath more coarse, and shape usu- 
ally more oval. 
Lobiopa brunnescens (Blatchley) 
Soronia brunnescens Blatchley, 1917, Can. Ent., 49 : 238. 
This species is definitely a Lobiopa and related to insu- 
laris. The types are from Dunedin, Florida, June 10. In 
addition there are specimens in the U.S.N.M. from Coving-
