Psyche 
[December 
Holotype deposited in United States National Museum; 
collected at Mt. Vernon, Virginia, Dec. 16, 1944, “in Andro- 
pogon” (J. C. Crawford). 
A single paratype female, data and deposition as for 
holotype, is very similar to the holotype in every way ex- 
cept that the gaster is slightly differently expanded. The 
measurements and proportions, except for the total length 
difference due to gastric expansion, are within the errors 
stated for the holotype. 
Psilobethylus lucidus n. sp. 
(Plate 13, figures 2, 3.) 
Holotype female: Similar to Ps . foveolatus, but smaller 
in size (see measurements below) and relatively more 
slender. Head more nearly perfectly oblong, with parallel, 
nearly straight sides, also more strongly depressed (index 
of cephalic depression 44±2). Eyes smaller, with only 
5-8 facets evident in each. Dorsal surface of head extreme- 
ly feebly convex dorsally, plane ventrally. In full-face 
view, posterior occipital border extremely feebly concave 
in the middle. Dorsum and sides of head with close but 
superficial “Scotch grain” coriaceous sculpture and a few 
sparse, widely spaced small piligerous punctures; the 
latter most numerous on the sides of the head, but even 
here not approaching in number or size the foveolae of 
the preceding species. Alitrunk with fine coriaceous sculp- 
ture much like that of head, but here punctulae are scarce 
and indistinct or altogether absent. Surfaces of head and 
alitrunk distinctly shining. Gaster smooth and shining. 
Hairs a little less abundant and shorter than those of 
foveolatus, particularly on cephalic dorsum. Color as in 
foveolatus, but lighter, the gaster not so distinctly darkened 
in the middle. Other characters, except for certain slight 
proportional differences shown in the figure, as in 
foveolatus. 
Holotype (U. S. National Museum) taken from the soil 
of a peach orchard in El Paso County, Texas, Nov. 2, 1936 
(W. F. Turner, No. T-1872).
