Sta^e II. — Elliptical, joint 13 quadrate, normal, narrowed behind. 

 Depressed spaces large and deep, all present; ridges and latticed ele- 

 vations between the depressed spaces densely papillose granular, 

 especially around the margin; sett« distinct, short, dark, pointed, 

 normal. All faintly whitish; latticed ridges of dorsal space 1 granule 

 wide. 



Stage III. — Elliptical, normal. Green, a yellow subdorsal line cen- 

 trally, reaching farther posteriorly than anteriorly; a round, red spot 

 crossing the subdorsal lines, but yellow edged and paler centered, sit- 

 uated on joints 7 and 8. 



Stage IV. — The purplish-red spot is rounded, a little larger th^n 

 before; yellow subdorsal line not quite reaching the extremities. The 

 larya now eats the whole leaf. 



Stage Y. — The patch is irregularly triangular, occupying about a 

 third of the dorsum; it covers depressed spaces (1) of tiye joints and 

 reaches the middle of the side; a red dash on joint 3. The yellow lines 

 reach to the anal end, but not to the head. 



StageVI. — The patch reaches the anterior and posterior extremities 

 narrowly, on the sides to the depressed space (4) of joints 7 and 8, 

 with a little point toward (4) of joints 6 and 9. It is as in the normal 

 T. testacea., except that the patch did not reach below the middle of 

 the side, being exactly as in some fully marked examples of T. csesonia. 

 The larya had but six stages. 



Eggs June 1, mature larya Jul}^ 14. 



Family PYRALID^. 



MELITARA JUNCTOLINgELLA Hulst. 



Larva. — Head rounded, slightly bilobed, held flatly; clypeus nearlj^ 

 reaching vertex, the sutures depressed; bright red-brown, epistoma 

 paler, ocelli black; width 2. 1 mm. Body slightly flattened, the segments 

 strongl3^2-annulate; cervical shield large but rather narrow, transverse, 

 shining black; anal plate very large, l)lack. Tubercles small, black, 

 i and ii in line, iv + v, normal. Feet with the crochets in an ellipse. 

 Dark purplish, nearly black; skin coarsely wrinkly shagreened; spira- 

 cles rounded, black. Thoracic feet brown; seta? flne, brown, rather 

 long. On the thorax ia -\- ib, iia -(- iib; on joint 13 anteriorly a medio- 

 dorsal shield and on joint 2 a small crescent before the spiracle, not 

 contrasted. 



Larvae feeding gregariously within the leaves of the prickly pear 

 cactus were found on the prairie near Denver, May 11. The}^ had 

 obviously passed the winter as half -grown larvse in this situation and 

 were feeding rapidly. However, it proved impossible to breed them, 

 and the above supposition as to their identity was gained from the cap- 

 ture of a female moth on the prairie near Golden, June 5.
