-. Smaller, 5-6 y 2 mm. ; clearer brown and less hairy with the 

 markings distinct; in the male black, clearly marked with 

 white ; margins of the face rectilinear or nearly so,

1. Ophiderma salamandra Fairmaire. 



Female: larger, more hairy and more obscure than the 

 next, the pale markings sometimes entirely obliterated in the 

 female. Color dull brown inclining to castaneous or sometimes 

 to olive. Face and front of the metopidium paler, sparcely 

 dotted or varied with rufous or brown; a brown point on the 

 base above each ocellus Callosities rufous. Markings fre 

 quently obscured ; when distinct there is a strongly arcuated 

 vitta from the middle of each lateral margin to the humeral 

 angle, connected by a transverse vitta directly across the dor- 

 sum over the posthumeral sinus; a transverse dorsal spot at 

 about the middle, nearly or quite connecting with the arcuated 

 vitta; and a basal transverse vitta near the apex. Usually the 

 arcuated vitta is obsolete anterior to the first transverse vitta, 

 and frequently the median spot or vitta is very obscure. Some- 

 times the metopidium has an arcuated line either side of the 

 median carina connecting with the anterior transverse vitta. 



In the male the front of the pronotum is usually mottled 

 with the callosities black, and the markings are obscured an- 

 teriorly and more distinct posteriorly than in the female. Here 

 the elytra are hyaline with a brown cloud at base and a triangu- 

 lar one at apex. 



This species I have seen only from New York, New Jersey 

 and Massachusetts although it doubtless occurs throughout the 

 northern states and Canada. 



2. Ophiderma pubescens Emmons. 



Smaller and more polished than salamandra. Female: 

 brown, more or less tinged with castaneous, or almost piceous. 

 Face and front of the metopidium pale or yellowish, more or 

 less dotted with ferruginous and sometimes with a black point 

 above each ocellus on the basal margin. Callosities generally 

 black. When fully colored this species has about the same 

 markings found in salamandra but usually there is a pale elon 

 gated vitta on the metopidium either side of the median carina.
