irregular raised lines. Abdomen one-third longer than the head and 

 thorax united, shagreened, segments i, 2 and 3 subequal in length, the 

 first very slightly the longest, segment 4 two-thirds as long as the third, 

 segment 5 a little shorter, the following still shorter, subequal. The ab

Described from 2 specimens, taken by Mr. Theo. Pergande, 

 in the nests of Camponotus melleus Say, May 29, 1895. 



The paper was briefly discussed by Messrs. Marlatt and How 

 ard, the former bringing up the point of the difficulty of associ 

 ating males and females in collected specimens, apropos to a 

 question by the latter as to the possible association of the Colo 

 rado male with the District of Columbia female.

NOTES ON THE DISTRIBUTION OF SOME INJURIOUS 

 INSECTS. 



By F. M. WEBSTER. 



In his very interesting paper, "Notes on the Geographical 

 Distribution within the United States of certain Insects Injuring 

 Cultivated Crops " (Proc. Ent. Soc. Wash., Vol. Ill, No. 4), 

 Mr. L. O. Howard has attempted to bring together some data 

 to show that some of our injurious species are more or less re 

 stricted in their habitat to certain life-zones, as mapped out by 

 Dr. Merriam. In doing this he has been obliged to criticise some 

 statements made by myself , first in Science for February 3, 1893, 

 and later in Bulletin 51, Ohio Agricultural Experiment Station, 

 w r here I gave the distribution of some of these species in Ohio, 

 with such information as I was able to obtain relative to their 

 probable introduction and subsequent diffusion. Knowing, as I 

 do, that Mr. Howard is as sincere in his position and as desirous 

 of getting at the truth as I am myself, it appeared to me that it 

 would be but just to myself and all interested to give the facts 

 upon which my statements were based. 



In August, 1892, at the meeting of the Association of Eco 

 nomic Entomologists at Rochester, N. Y., specimens of Crio- 

 ceris asparagi were found near the city, and this was, at that 

 time, supposed to be their extreme western point of occurrence. 

 A year later I received specimens, in all stages of development,
