Resembling atropunctata in structure, rather longer and 
narrower. Head and anterior part of pronotum pale, 
w T ith 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. Eyes, small, hardly as wide as the 
pronotum at the lateral angles; pronotum, rather long, narrowing 
anteriorly. Elytra, long and narrow; venation of th s hieroglyphics 
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 spots, 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 anten- 
nal pit®, another pair below these, and a third pair on the gerce. 
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 ro w; posterior disc tinged 
with reddish, with four longitudinal testaceous lines, the outer 
pair short and divergent; scutellum, yellow, with the transverse 
suture, and three dots at base, reddish fuscous; sometimes the basal 
dots are extended into longitudinal lines. Elytra, broadly pale 
along the nervures, 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 Dazee 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 as T. aurora Uhler, and are doubtless from the
