straight lateral arms each of which apparently re-divides, the re- 
sulting two rods running closely parallel and terminating in sac-like 
structure; (2) pair of long median arms, each of which re-divides 
near its base, the median sub-branches of the two sides curving toward 
midline and crossing near their tips; lateral sub-branches each sur- 
rounded nearly to tip by thin-walled sac containing granules. An- 
terior and posterior margins of clunium thickened. Clunial papillar 
fields (fig. 12) distributed as follows: two transverse lateral fields 
at about one-third distance from anterior to posterior margin ; two 
rounded lateral fields at about two-thirds distance from anterior to 
posterior margin; a transverse field along posterior margin with 
slight median interruption. A small papillar field on pre-clunial 
tergum. Paraproctal sensorium with 9-10 trichobothria and 1-2 
setae without basal rosettes. 
Color (in alcohol). — Body and appendages largely dull ivory 
yellow. Compound eyes black. Reddish brown pigment distributed 
as follows: inner rims of lateral ocelli and upper rim of median ocel- 
lus, a small circle antero-ventral to each antennal base, a spot between 
compound eye and antennal base, a line along suture between ante- 
and post-clypeus but absent from broad central region, an irregular 
spot above each subgenal suture, a broad band along each side of 
thorax, an arc around pleural border of each coxa, an irregular band 
along each side of abdomen from base to clunium, the bands of the 
two sides connected by transverse dorsal bands in segments 3, 4, and 
5, and by broken transverse bands in segments 6 and 7; papillar 
fields of clunium, posterior edge of epiproct, and ventral edges of 
paraprocts with same pigmentation. 
Female. — Measurements (Table I). 
Morphology. — Subgenital plate (fig. 14) with posterior margin 
approximately straight and beset with 11-12 strong setae. T-shaped 
sclerite and interior plate absent. Ovipositor valvulae (fig. 13) : first 
valvula with broad, rounded basal appendage; third valvula very 
slightly bilobed apically. Paraproctal sensorium with 8-10 long tricho- 
bothria and 2 long setae lacking or with weakly developed basal 
rosettes. 
Color (in alcohol). — Same as in male. 
Type locality. — La Union near Villa Juarez, Puebla, Mexico, 
November 3, 1963, E. L. Mockford collector. Holotype cf, allo- 
type $, 1 1 cf an d 12 $ paratypes and 7 nymphs. Types are for the 
present in the author’s collection.
