142 THE CANADIAN ENTOMOLOGIST. 



Schwarz, and the papers of Drs. Leconte and Horn of a few years back are 

 full of allusions to species collected there by him. I hoped to find it an 

 interesting field, and was not disappointed. 



Most of the work was done along the river bottom, where the cotton- 

 wood timber was usually sufficiently free from underbrush to admit of 

 freedom of movement and of sight. The felled trees, when the bark was 

 peeled off, furnished Toxidium compressum, Litargits balteatus, Epierus 

 regular is and Bacanius punctiformis. Beneath the old trunks were found 

 B lap st inns fort is and arenarius. The cow-droppings were productive of 

 Copris Carolina, Phandics triangularis, Onthophagus pennsylvanicus, 

 Aphodius tenuistriatus and stercorosus and Cercyon variegatum. The 

 banks of the river were covered with Cicindela rectilatera and C. sperata; 

 Tetragonoderus fasciatus and T. latipennis, the latter abundant, were to 

 be obtained in more circumscribed spots with a species of Stenus near 

 stygicns. The weeds on the bars, on being pulled up, were found to 

 shelter around their roots a colony of Agonoderus comma, Atithicus 

 difficilis, A. nanus, Metachroma interrupta and Myochrous denticollis. 

 This Myochrous was also often found feeding on willows. 



On leaving the immediate vicinity of the river and working along the 

 roads, Languria Iceta is found commonly with Acylomus calcaratus and 

 Conotrachelus leucophceatus. Arriving at a point where a little creek 

 crossed the road, I ascended it, and where a tree had been felled across it 

 some years ago and was consequently in a rather advanced stage of decay, 

 settled down for an hour or two of solid work. By peeling off the bark 

 carefully I was able to get everything worth taking, as whatever was nim- 

 ble enough to escape my bottle at first, fell into the water and was easily 

 secured. The results were two Mallodon dasystomus, several Eupsalis 

 minuta, Platydema ruficorne, flavipes, Imdpes, Eustrophus bicoloi', and 

 several other things. Leaving this spot and going on to a freshly cut 

 mesquit, I got under the loose bark four or five specimens of Conotrachelus 

 anaglypticus, a few Carpophilus semitectus. and some Laemophlceus 

 chcemeropis. Under damp logs I found the specimens of larvae, pupae 

 and imagines of Epipocus described in another paper. 



After a week's stay at Columbus I moved on to Harwood, which is at 

 a considerably higher altitude — here the cottonwoods were gone and re- 

 placed by mesquit and oak, much of it "scrub." The collecting was not 

 nearly so good and of a different character, Elcodes tricostata being one of 

 the most prominent beetles. Two or three Pasimachus were found under
