MQ?>Qmh\\\-i^atropn)ictata in structure, rather longer and 

 narrower. Head and anterior part of pronotum pale, 

 with transverse rows of spots, rest of pronotum and elytra 

 pale reddish, with darker stripes. Length, 7 mm.; width, 

 1.25 mm. 



Vertex, bluntly rounding, three-fourths the length of the pro- 

 notum, narrower than in the preceding species, the disc very flat, 

 slightly transversely depressed. P^yes, small, hardly as wide as the 

 pronotum at the lateral angles; pronotum, rather long, narrowing 

 anteriorly. Elytra, long and narrow; venation of iht-fiieroglyphica 

 pattern, the anteapical cells longer and narrower; outline of face 

 as in that species. 



Color; vertex, pale creamy; a spot at the apex, which is one of 

 five equidistant ones on the anterior margin, and behind these a 

 pair of oblique dashes with their inner ends enlarged and obliquely 

 truncate; black. Posterior sub margin with four quadrate red- 

 dish spols, the inner pair elongate. Front, pale; three longitudinal 

 lines, the median line not reaching the apical dot, either side of 

 which there is a black dash below, a pair of spots below the auten- 

 ual pit", another pair below these, and a third pair on the get a3. 

 Clypeus, with a black dash above. Pronotum, with the anterior 

 part light, broadening out behind the eyes, the sub-margin with six 

 quadrangular reddish fuscous spots in a row; posterior disc tinged 

 with reddish, with four longitudinal testaceous lines, the outer 

 pnir short and divergent; scutellum, yellow, with the transverse 

 suture, and three dots at base, reddish fuscous; sometimes the basal 

 dot.s are extended into longitudinal lines. Elytra, broadly pale 

 along the uervures, the central portion of the cells darker. Legs, 

 yellow. 



Genitalia; female segment over twice the length of the penulti- 

 mate; posterior margin, broadly roundingly produced; disc, con- 

 vex. Male plates, one-third longer than the ultimate segment; 

 rather broad at base, rapidly narrowing to the long acute points, 

 which are much exceeded by the pygofers. 



Specimens are at hand from Arizona and Mexico. The 

 Arizona specimens are from the Van Duzee collection, and 

 bear the label, "Ariz. C. U., Lot 34," and under this, "Cor- 

 nell U., Lot 45, Sub. 410." They were sent to Prof. Van 

 Duzee asvT. aurora Uhler, and are doubtless from the
