286 ENTOMOLOGICAL NEWS. [November, 



found a deep " blow-out" close up to and on the north bank of 

 the stream. Here, running over the sides and bottom of the 

 *' blow-out" I found them in considerable numbers. They were 

 very active little fellows, but I succeeded in taking twenty-five 

 •or thirty in two hours' work with the net. 



The surface I collected over was not over ,one hundred feet 

 square, and they were taken only on sand without vegetation, or 

 sparsely covered with grass. 



I visited the same locality May 31st and June ist, of this year, 

 and found the beetles at the same "blow-out." The weather 

 was cooler and took only a dozen specimens from 3 to 4 p. m. 

 The next morning I took the first specimens shortly after 9 a. m., 

 and up to 11.30 had taken over thirty specimens. I was told by 

 a resident that he had seen this insect in large numbers at a large 

 "blow-out" eight or ten miles farther up the valley of the 

 Frenchman. He called them "calico" bugs. The species 

 taken in this locality diflfer somewhat from those further north- 

 west. E. A. Schwartz, of the Division of Entomology, Wash- 

 ington, D. C. , says: "Your Cicindela linibata are smaller than 

 those collected by Bruner, and with the green markings wider. 

 I do not doubt that there is somewhere in Nebraska or further 

 north where specimens will be found intermediate between lini- 

 bata and borealis'' 



My specimens had, with two or three exceptions, green or blue 

 markings. The exceptions were coppery bronze. While making 

 these two trips I collected at Superior, Culbertson and McCook, 

 and found some very good things. The list includes: 



Cicindela scutellaris, at Culbertson and Imperial. C. leco7itei, 

 at Superior. C. formosa, at all three places. Chlcenius sericeus, 

 nebraskensis and Brachylobus lithophilus^ at Culbertson. Hister 

 subrolundus a.nd nubilus, and Saprinus pennsylvanicus, fraternus 

 3ind patrice lis, at Superior. Carpophihcs pallipennis, at Imperial. 

 Meligethes mutatus, at Superior. Hydnocera mbfasciata, at Im- 

 perial. Ptilinus thoracicus, at Superior. Canthon nigricornis , 

 at Imperial ; I have the same species from Florida. Canthon 

 ebenjis, at all three places. Aphodius ruricola, at Superior and 

 Culbertson. A. dentiger, at Superior. A. walshii, at Superior 

 and Imperial. Lachnosterna crassissima, at McCook. Poiy- 

 phylla 10- lineata, at Imperial ; very far east for this species. 

 Cremastochilus knochii, at Superior. C. nitens, two specimens
