ocellus, not continuous; crochets evenly biordinal, alternating one long 

 and one very short hook, 40 to 44. 



Larvae collected November 24, 191 8, at Kountz, Tex. Moth issued

A large series of moths was reared April 23 to May 5, 1919, from larvae 

 collected at Brownsville, Tex., April 7, 1919, by E. L. Diven. The larvae 

 feed in the flower heads of a composite, making an untidy patch and 

 eating the bloom, stem, and seeds. The species appeared to be very 

 common. 



The larva is pale smoky brown, longitudinally marked by two narrow 

 white dorsal stripes and a similar lateral stripe; spiracles black, thoracic 

 legs smoky fuscous; anal shield yellow, thoracic shield yellow, broadly 

 margined laterally and posteriorly with black ; head pale yellow, mottled 

 with yellowish brown and with a broad lateral black band and a blackish 

 shading toward anterior margins of epicranium; ocelli distinct; ocellar 

 pigment absent or confused in the lateral black of epicranium; general 

 structural characters as in Moodna ostrinella; width 6 to 7 mm. 



The interesting and rather complicated genitalia of the male adult are 

 figured in Plate 100, B.

CLYDONOPTERON TECOMAE RILEY

The larva of this species feeds only in the seed pods of the trumpet- 

 flower vine (Tecoma radicans) . It is mentioned here only because its host 

 plant is often found in the neighborhood of the cotton fields and for that 

 reason it might be confused by the uncritical with the larva of Pectino- 

 phora gossypiella. It is easily distinguished, however. The spiracles 

 are rather large, oval, and black, the edges are heavily chitinized, and the 

 spiracle on the eighth abdominal segment is somewhat larger but no higher 

 on the body than the others; the proleg crochets are arranged as in the 

 Aegeriidae — that is, uniordinal and in two transverse bands — and the 

 prothorax has only two setae on the chitinization before the spiracle as in 

 other Pyralidae. It pupates in a cocoon within the seed pod. 



Moths were reared by us August 30 to September 15, 191 8, from larvae 

 collected earlier in August (Anahuac, Tex.) the same year.
