Cerambycid(£. seldom came, the only species I saw being 

 Prioniis f ocularis and Criucephalus asperatus. ChrysomdidcB 

 were very rare. The TenebrionidcB being in great part 

 wingless were also scarce, though I found two or three 

 Eleodes siUuralis around the base of one pole on which the 

 globe was set. Hynicnorus was the sole representative of the 

 Cistelidce, Oxacis bicolor of the CEdenieridce. Two or three 

 specimens of Anthiciis biguttuliis were taken by a friend at 

 the sanr.e light after I had left Albuquerque. 



Macrobasis longicollis was attracted quite frequently, and 

 one night I took sixty-three specimens of M. atrivdtata, a 

 very fine species. Except on this one occasion I never took 

 more than two or three specimens of atrivittata in one evening. 

 I was told that Pyrota mylabrina came to light in August 

 but being away was unable to verify the assertion. 



In connection with the above a note on the common mode 

 of occurrence of these two species of Macrobasis may not be 

 out of place. AI. longicollis occurs in immense numbers on a 

 species of Solanuiii, almost covering the plant in many cases. 

 On being approached they quickly loosen their hold and drop 

 to the ground and make off at a good rate, seldom flying 

 however. The Solanum on which it feeds is the food plant 

 of the notorious "Colorado beetle," Doryfhora decendineata^ 

 which has adapted itself to the climate of every part of our 

 country where the potato is raised. May not our Macrobasis 

 prove a serious pest to that useful vegetable if its cultivation 

 should be attempted on a large scale in the valley of the Rio 

 Grande ? 



The other Macrobasis — atrivittata — is found in the same 

 places but much less commonly. Both species feed only in 

 the morning and evening, disappearing during the heat of the 

 day. 



As far as my experience went, the CurculionidcB were not 

 attracted to light, though I have known them to fly into a 

 lighted room at night in Iowa. The best places to capture all 

 the night-flying species were at the globes in front of private
