first and second sub-marginal cells heavy and dark colored; discal 

 cell rather small emitting four posterior veins; legs black, knees and 

 tarsi lighter colored than the other parts ; abdomen short and wide. 

 Five males and four females taken at Hawkins, near Akron, Ohio, 

 May 21, 1899. 



This is so distinct from species of Nemotelus in general appear- 

 ance, and structure of the head, especially in the male, that it seems 

 best to make it the type of a new genus. 



Chrysochboma nigricornis Loew. 



This is a common species in southern Ohio. Specimens may be 

 found resting on the upper side of leaves and are easily approached. 

 In the female the white fronted line which Loew mentions is very 

 conspicuous and extends from one eye to the other above the anten- 

 nae. In some specimens the white lateral, thoracic lines are very 

 easily seen, but in others these lines are brownish. The male has 

 much the appearance of the female, the eyes are broadly contiguous, 

 leaving a small vertical triangle which is largely occupied by the 

 ocelli ; the lateral thoracic lines in this sex are dark brown and 

 therefore are not such a contrast to the bright green thorax as in 

 the female. 



I had some trouble in locating the genus of this species by Dr. 

 Williston's key. The species is not elongate, but of much the same 

 form as Microcrysa polita. A comparison was made with the type.

 Max Morse. 



Fam. Proteid^. 

 Necturus maculatus Rafln. University Lake, Olentangy River, 

 and Lake Erie. Near Sandusky, on both the Lake and Bay shore, 

 decaying specimens of the mud-puppy, mostly young, were found in 

 numbers in 1900. Almost all were covered with a fungus— probably 

 Saprolegnia. 



Fam. CRYPTOBRANCHIDiE. 



Cryptohranchus alleganiensis (Daudin.) Columbus. 

 Fam. Amblystomatid^. 



Amblystoma opacum (Gravenh). Portsmouth and Sugar Grove. 



Amblystoma tigrinum (Green). Columbus. This salamander ap- 

 pears early in the Spring and is often found in small pools. Indivi- 

 duals are taken nearly every Autumn in the basement of the 

 Biological Hall while they are seeking shelter. A specimen taken 

 thus had many characteristics in common with xiphias Cope and 

 it is doubtful how valid xiphias is, as a species.
