106 NATURAL RESOURCES SURVEY 



Kolla (Tettigonia) hieroglyphica var. uhleri, Ball. These 

 last three insects are very abundant everywhere in the valley 

 from Mar. to Oct., and although they usuallyescape notice, 

 because of their small size they really do much damage to 

 Alfalfa. Var. dolobrata of the last species also ascends into 

 the Yellow Pine Assn. 



Murgantia histronica. The Harlequin Cabbage Bug is 

 sometimes very abundant on Cleome and on cabbage sprouts 

 that early in the spring grow up from stumps left in the 

 field. It does not seem to be a very serious pest to the 

 cabbage crop as in some localities in the East, possibly 

 because it prefers the Cleome. Occurs also on Biqelovia. 



Nysius senecionis, Schill. On Solidago especially. 



N. ericae. More abundant even on Senecio than the last 

 species. 



Strictocephala festina, Say. On alfalfa where it occasionally 

 does some damage, causing the stems to turn yellow and die. 

 Also occurs with the next species on Chrysothamnus pul- 

 cherrimus in the Cedar Assn. 



S. gilletti. 



Anasa tristis. The squash-bug is very abundant on cul- 

 tivated squashes. Although it has never been found feeding 

 on any wild plants, it commonly hibernates under yucca 

 stems miles from any cultivated fields, showing that the 

 adult beetles commonly fly at least two miles. 



LEPIDOPTERA. 



* Chorizagrotis balantis, Grote. Not listed from N. M. in 

 Holland's Moth Book. Another Colorado type that extends 

 down the valley of the Rio Grande. 



Heliothis armiger. Exceedingly abundant especially on 

 sweet corn. Every year in the writer's garden for the four 

 years that he tried to raise the crop it was infested by at least 

 one of these "corn-ear worms" and more generally harbored 

 three or four. 



Pieris rapae. Common in the valley but does not seem to 

 have become established in the mountains. 



Here only one occasionally finds a toad (Bufo sp.) and frogs 

 (Rana virescens) are fairly common.
