impression less deep. Elytra red, of the same form as in F. 

 cavifrons. Abdomen with the first segment very short, and 

 narrower than the elytra; the second is twice as long as the 

 first and equal to the third or fourth segment, gradually 

 increasing in width from base to apex, the rest of the seg- 

 ments rapidly decreasing in width and seemingly so in length, 

 as they are retracted in dead specimens. 

 Habitat. San Francisco, Cal.

AnOPS, 11. P". (from a, zvanting\ and oi/i, eye.\

Head as wide as long, vertex quadrate, carinate at the sides, 

 the carinfe nearly obsolete posteriorly, with two shallow fove« 

 less than one-fourth from the base, and mutually three times 

 farther distant than either from the basal carinas; circumam- 

 bient sulcus shallow near the foveas, deeper and wider near 

 the frontal margin. Supra-antennal tubercles retusely angu- 

 late outside and separated by a notch from the arcuate frontal 

 margin; clypeus evenly rounded, punctured; sides of the head 

 continuously convex with the posterior part of the vertex and 

 the gular region, and with a strong, pointed, conical spine 

 (perhaps bearing an ocellus) in the position usually occupied 

 by the eyes; occiput carinate in the middle.; gula unicarinate; 

 neck faintly carinate; mentum and labrum very short, emargi- 

 nate; antennal cavities shallow. Palpi with the second joint
