This curious insect was found on the shore of a salt lake in the northern part 

 of the great Colorado desert. It runs very actively and frequently takes flight, 

 like Cicindela or Bembidium. 



Keddish brown, with very fine cinereous hair. Head flat, quadrate, shining, 

 finely punctured, posterior angles rounded, occiput channeled, margin almost 

 acute. Thorax narrower than the head, a little longer than wide, trapezoidal, 

 slightly narrowed behind, base finely margined, slightly foveate in the middle ; 

 disc flat, finely punctured ; elytra not wider than the head, parallel, truncate at 

 base and tip, opaque, very finely and densely punctured, dusky towards the 

 base. Legs long, moderately slender ; posterior tarsi nearly as long as the 

 tibiae. The male has the anterior tarsi a little dilated. 



2. T. alutaceus, elongatus, fere depressus, niger, subtilissime alutaceus, 

 brevissime pubescens, capite postice subtruncato, thoraceque punctulatis, elytris 

 obsolete punctulatis, antennis testaceis articulo ultimo praecedentes duos 

 aequante. Long. -1. 



Anthicus ahitaceiis Lee. An. Lye. 5, 155. 



Found at San Diego, California. A much smaller specimen, with the head 

 more rounded behind, was found at the Gila. 



Elongate, almost depressed, black, opaque, scarcely pubescent. Head large, 

 slightly convex, finely punctured, base truncate, with the margin not acute, 

 posterior angles broadly rounded. Thorax narrower than the head, trapezoidal, 

 narrowed behind, base margined ; finely punctured. Elytra scarcely wider than 

 the head, truncate at base and tip, very finely rugous, and very obsoletely punc- 

 tured. Posterior tarsi shorter than the tibiae. The last joint of the antennae is 

 here only twice as long as the preceding, and the constriction is at its middle, 

 so that it appears like two ordinary joints. It was not until I removed the 

 mould very carefully, and counted the joints, that I became aware of the aflfinity 

 with the first species.
