30 THE CANADIAN ENTOMOLOGIST. 



the ordinary tides: D. sphcericoUis, 7 sp.; D. pallipennis, 2 sp.; D.fili- 

 formis, i sp.; D. pumilus, 10 sp.; Clivina striatopunctata, 5 sp.; Bledius 

 politus, 16 sp.; B. basalis, 20 sp.; Trogophlanis 1 sp., 12 spec; Rhysse- 

 tnatiis scaber, 18 sp.; many Bleditis viaxillosus around the base were not 

 collected. The Dyschirius, Clivina and Bledius burrow only deep 

 enough in the moist sand to fairly cover themselves, and their presence 

 is known by the little mounds at the entrance of their excavations. In 

 life the elytra of Bledius basalis are pearly white, with the basal declivity 

 black ; those oi B. politus are reddish-yellow and shining, and the thorax 

 is ferruginous, and it may be known from all others of its size by the deep 

 thoracic channel and the sparse coarse punctuation of the thorax and 

 elytra ; the head of the male is large, and tuberculate between the ocular 

 ridges ; both species extend southward along the coast to Florida. 

 Rhyssematus scaber does not burrow, but lives beneath a thin layer of a 

 confervoid growth that forms on the marshes and about the roots of grass. 

 This little beetle feigns death so persistently that I never saw one move 

 in the least, and the only other Aphodide I know of that has this habit is 

 Dialytes striahdus. 



Lebia vivida Bates. A specimen of this beautiful little beetle, 

 described from Mexico and introduced into our catalogue on the strength 

 of two specimens taken in Arizona, is in my collection through the kind- 

 ness of Mr. T. D. A. Cockerell, taken by him in Custer Co., Col., at an 

 elevation of some 8,000 feet, thus showing that it belongs to the fauna of 

 the Rocky Mountains. 



Cychrus Lecontei Dej. Most of the Carabid?e have a regular time of 

 appearance, but this does not seem to be the case with Lecontei, bright 

 new specimens of which may be found from April to December. I have 

 found them paired in November, in April, and at various times during 

 the summer. It hibernates, as is well known, in logs and under moss 

 and stones. 



Chlcenius Pennsylvanicus Say is subject to considerable variation in 

 color, size and sculpture, but nothing is seemingly stable enough to form 

 a race or true variety. One of these variations I was once disposed to 

 regard as a species till set right by Dr. Horn. It has pale epipleura, and 

 the side margins of the ventral segments rufous, like Circumcinctus ; the 

 puter three intervals of the elytra are dark green, contrasting with the 

 the d^rk disk. It pcgurs here in summer on the river beach, and I have
