dad, Durango, has not been confirmed. Ciudad is about 75 miles 

 northeast of Mazatlan. 



The Roberts specimen from west of San Luis Potosi is almost a 

 topotype, as the type locality is located 10 to 15 miles south and 

 slightly west of that city. 



Dr. Roberts informs me that all his specimens of miguelitana 

 were collected under ecological conditions varying from open 

 woodland to dry scrub country, none under desert conditions. 



CONALCAEA CANTRALLI, new species 



Figures 58, e, h, j, m; 59, c, /; 60, e, /; 62, 63, a, d, g, h; Plate 10, Figure 3 

 Male (holotype) . — Size medium to large for genus. Head slight- 

 ly narrowed in front, basally subequal in width to anterior part 

 of pronotum ; pronotum gradually widening posteriorly, shaped as 

 in fig. 63, d; tegmen barely extending onto abdominal tergum 2, 

 shaped as in plate 10, figure 3; figure 58, h; supra-anal plate 

 wider than long, deeply furrowed medially, the adjacent lateral 

 ridges longitudinally wrinkled, lateral one-third of plate broadly 

 concave on each side, toothlike prominences present, furcula not 

 evident (fig. 63, h) ; cercus conspicuously lobate, the mesal surface 

 excavate in apical third due to curvature, apex projecting some- 

 what ventrally and more noticeably mesally, exterior surface of 

 apical third shallowly pitted as illustrated (fig. 60, e) ; subgenital 

 plate bluntly conical (fig. 58, m) ; dorsal valves of aedeagus elon- 

 gate, broadly and inconspicuously projecting anteriorly (fig. 59, /, 

 A-m) , posterior projection only moderately developed (fig. 59, c, 

 pe) , posterior surface of apical third darker and of a less mem- 

 branous texture mesally (m) than laterally; ventral valves con- 

 cave on inner surfaces (c) , posterior exterior surfaces with small 

 basal flap (f ) ; epiphallus with ancorae acute, tapering, directed 

 ventroanteriorly (less triangular in shape than appearing in fig- 

 ure 63, a, because of direction of that view) , lophi tall, the dorsal 

 margin broadly and evenly rounded. 



Coloration: Essentially as in coyoterae; disk of pronotum Ro- 

 man sepia ; face and lower part of lateral lobes of pronotum pale 

 brown ; ventral surface and lower sides of abdomen straw yellow, 

 also a mediolongitudinal band on terga 2 to 6; dark postocular 

 bar indistinct on head, black and well defined on lateral lobe of 

 prozona, grading into pale brown on ventral half of metazona; 

 dark pattern on meso- and metepisterna typical of coyoterae, 

 black on costal half of tegmen, on dorsal half of sides of terga 1 

 to 7 grading to dark chestnut ; antennae pale brown ; hind femur 

 with blackish brown longitudinal bar much as in h. huachucana; 

 hind tibia vermilion.
