Ischnorhynchus didymus Zetterstedt. 



Three specimens. A common European insect ; it has become 

 quite common here also, and is found all over the United States 

 and in Canada. 

 Lygceus turcicus Fabricius. 



A fine set of specimens of the variety L. reclivatus Say, that 

 shows the white markings on the membrane very distinctly. The 

 species is very abundant. 

 Melanocoryphus fascetus Say. 



Four specimens. The species is described by Say from Florida. 

 It is subject to great variation in the red markings on the thorax 

 and abdomen. The bug inhabits the southern States and the 

 West, and seems to be very common in some localities. Speci 

 mens of this species have previously been found on the snow fields 

 of Pike's Peak. 

 Lygus sp. 



One example of a Lygus. It is too much distorted for specific 

 determination. 

 Aradus sp. 



A single specimen, a male. Probably a new species, but hav 

 ing only one specimen, and not knowing the other sex, it is not 

 advisable to describe it. 

 .Idiocerus lachrymalis Fitch. 

 Thamnotettix sp. 



NEUROPTERA. 



Limnephilus concolor Banks. 



Three specimens, the only species of Neuroptera represented 

 in the collection. The species has never before been reported 

 from Colorado, though it probably occurs quite widely distributed 

 through the northwestern States. It was described from the 

 State of Washington. These specimens taken on snow were in 

 very poor condition and very much resembled the rubbed speci 

 mens of unidentified Pyralids mentioned under the head of Lepi- 

 doptera. 



In discussing the paper, Dr. Dyar referred to the extreme 

 abundance of Clisiocampa fra^il/.s on Pike's Peak almost up to 

 the timber line. Mr. Cook remarked that the Myriapoda were 

 especially good material for the study of geographical distribution. 

 as their manner of life restricted their range very effectively. 

 With the exception of a few large centipedes, one almost cosmo 

 politan species being mentioned in particular, hardly anv myria-
