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. 
Chrysochroma 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.

Fam. Proteidje. 
Necturus maculatus Rafin. 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. Cryptobranchid^e. 
Cryptobranchus alleganiensis (Daudin.) Columbus. 
Fam. Amblystomatidje. 
Ambly8torna opacurn (Gravenh). Portsmouth and Sugar Grove. 
Ambly stoma 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.
