Our notes upon it arc meager, but indicate that the life history is 

 probabl}" the same as for the last species. The adults emerge from 

 hibernation about the last week in March, though specimens were sent 

 us from Ondee, Tex., January 25, 1903. The adults are most abun- 

 dant during June and July. Mr. Lewis observed the oviposition 

 at Terrell seTeral times. The eggs are laid just beneath the epider- 

 mis, ten or twelve in a row, in practically the same manner as by 

 //. trUiuetra.

During the preceding summer we endeavored to rear the nymphs 

 in a tield cage, but all died. It would seem that there are two distinct 

 generations, the larger numl)er 

 occurring in July being the new 

 adults, which oviposit in August. 

 Professor Ball, however, finds 

 but one generation in Colorado. 

 He writes us as follows: 



The species (0. lutcralix) is but single 

 brooded in all parts of Colorado from 

 the coldest to the warmest. The adults 

 hil^ernate over winter, as do all of the 

 tettigonids here, and are common from 

 the middle of March into June, most of 

 them disappearing by the middle of that 

 month; but a few scattering ones run on 

 into July. They lay eggs in May and June. The first larv;e apjiear about May 24 and 

 continue to cnne out through June, the last ones disappearing in August, about the 

 15th. Fresh males appeared July 6 — the females not until later — and ran on tiirough 

 the season, without mating or developing eggs. Thus there is a wide variation in the 

 time of appearance of all stages; one could find nearly full grown larva' in June and 

 again in August, two months later". From almost daily ol)servationH on a single area 

 where they were common, I am very positive that there is but one brood. 



The difference in latitude l)etween Colorado and Texas — equal to 

 that between Washington, I). C, and Jacksonvillo, Fla. — however, 

 will easily account for another l)rood occurring in Texas,

DESCRIPTION OF NVMIMI, BY E. ]>. K.MJ,. 



-Head much longer and more infiated than adult, with about the same anterior 

 slope. Front longer and narrower, proportionately, giving the larva a much more 

 pointed head as viewed from the side, and a long sloping face. Color: pale, creamy 

 yellow, a round black sjwt at apex of head; from this two fairly delbiite dark stripes
