stricted distiid. iSui)r;i-anal plate triansularly produced, lateral inargiiis 
converseiit and broadly concave, then broadly convex to the sulrtruncate 
apex. .Subgenital i)late large, scooi)-shaped, extending a little bc'yond apex 
of supra-anal jdate, lateral ]iortions ])roduced and raised, with margin convex 
to point opposite cerci, there broadly obtuse-angulate rounded eniarginate, 
with remaining jrortion of free margin broadly convex to a very l)rief]y longi- 
tudinal, meso-distal cleft. 
Coloration of type. Head with a pair of vague brown suffusions l)etween 
the eyes and ocelli, between the antennal sockets and above the clyi)cus, 
these fusing with each other and with a brown suffusion mesad on the clypeus, 
leaving a conspicuous huffy weflge-sha])ed area mesad on the face; vertex, 
ocelli and areas between the brown suffusions huffy. Palpi, limbs and under- 
[rarts ochraceous-buff tinged with tawny, the abdomen with a heavy sub- 
marginal band of deep prout’s brown on each side. Pronotal disk ochraceous- 
buff tinged with tawny, delicately pictured with blackish prout’s brown, 
lateral portions and tegmina weakly transjiarent, faintly tinted with buck- 
thorn brown. \\'ings transparent, similarly tinted in anai of costal veins, 
elsewhere more faintly .so. Dorsal surface of abdomen suffused with j)rout’s 
brown, margined with ochraceous-buff. 
Allotype very similarly, but much more intensively, colored, not tinged 
with tawny. Head markings heavier and che.stnut lu’own, base of first an- 
tennal joint and i)alpi to near tips of last joint of this color. Cei)halic femora 
chestnut brown, i)aling to huffy dorso-distad; other femora huffy, margined 
with chestnut brown. Tibiae huffy, heavily decked with chestnut brown at 
bases of si)incs. Tarsal joints huffy, first thrc'e suffused with chestnut Irrown 
distad. Pronotum similarly Imt more heavily ])ictured with chestnut brown. 
Abdomen, above and below, .solidly chestnut brown, margined with huffy. 
A paratj’pic male, from the .^tate of .Sinaloa, shows a most striking intensive 
coloration of head and pronotal disk, the suffusions becoming more solid and 
sharply defined, the vertex streaked vertically with brown, and the picturing 
of the pronotal disk heavier and more (amspicuous. 
The other paratypic male, from Lower (kilifornia, shows a very slightly 
greater rece.ssion of the color pattern than does the ty|)e. 
Df the juveniles, that from Lower (California shows the maximum of re- 
cessive coloration in the series, with pronotal picturing almost olisolete and 
cephalic markings reduced to vague dots. The juvenile from .Sinaloa is 
nearly as intensively colored as the adult from that- state. In consec|uence 
these juveniles have a very different superficial api)earance.
