1876.] 11 [Austin. 



This species, which has been confounded with compotens Lee, dif- 

 fers from that species by its smaller size, shorter and thicker antennae, 

 and darker feet. It is apparently the most common species in the 

 Pacific district. I have specimens from Nevada, various parts of Cal- 

 ifornia and British Columbia; it is a much stouter species than the 

 two preceding or the following. 



9. Paederus littorarius Grav., Mon., 142 ; Er., Staph., 656. 

 littoralis Oliv., Encycl. meth., vin, 627. 



Head orbicular, black, sparingly and rather coarsely punctured on 

 the sides, a depression on each side opposite the eyes more densely 

 punctured. Mouth parts red; maxillary palpi sometimes blackish at 

 apex. Antennae as long as the head and thorax, a little thickened 

 externally, joints one to four and two or three terminal ones red, the 

 rest dark red to black, third joint a half longer than the second, fourth 

 to tenth gradually shorter and a little thicker, eighth to tenth longer 

 than broad, eleventh obliquely acuminate. Thorax red, oval, sides 

 and angles rounded, narrowed behind; disk with two rows of, and a 

 few scattered, punctures on each side. Elytra a little larger than the 

 thorax, blue, coarsely and densely punctured, punctures sometimes 

 confluent, particularly on the sides. Abdomen with the two terminal 

 segments black, others red, sparingly and finely punctured; meta- 

 sternum black, sparingly punctured. Legs red, with the knees 

 and tarsi sometimes blackish. This is the most common species 

 throughout the Atlantic region; it may be distinguished from palus- 

 tris and floridanus by the more densely punctured elytra, and from 

 nevadensis by the paler legs and antennae, and by being more slender.
