AMERICAN COLEOPTERA. 81 



eight abdominal segments on the upper and lower faces, the first ventral 

 is however entirely membranous and almost concealed by the coxae. 



The body is not apterous, but the wings are short and feeble. 



One specimen, Fort Tejon, California ; in cabinet of Dr. Leconte. 



E. PRETiosus % Lee. — This species excepting the antennae has more 

 the form of some of our Asaphes. The antennal character is the only 

 constant one for the separation of this from lautus. The thorax is 

 usually as broad as long but this is not constantly so. The surface is 

 however less coarsely punctured and at base more finely than in lautus. 

 Length .72 inch ; 18 mm. PI. I, fig. 4. 



This species is the one referred to by Lacordaire, ( Genera iv, p. 233, 

 note), and through the kindness of Mr. Alexander Fry of London, 

 I have one of the specimens. 



Occurs in the Coast Range region at and north of Santa Barbara. 



E. pretiosns 9 .—Elongate, cylindrical, slightly depressed, rufo-testaceous, 

 moderately shining, very sparsely pubescent, body feebly winged. Head moder- 

 ately densely punctate, vertex slightly impressed. Antennfe slightly passing the 

 middle of the thorax, somewhat variable in structure. Thorax a little wider than 

 long, anterior angles rounded, sides very feebly arcuate, hind angles slightly 

 divergent and carinate, surface sparsely punctate and with a slight depression 

 each side at the end of the carina. Elytra as long or a little longer than the head 

 and thorax and covering the first two abdominal segments, sides arcuate, apex 

 slightly prolonged, suture dehiscent, striate, striae not punctate, intervals sparsely 

 punctulate. Prosternum coarsely punctate, the side pieces quite smooth, meta- 

 sternum and abdomen sparsely punctulate. Abdomen above very sparsely and 

 finely punctulate. Length .80— 90 inch ; 20—23 mm. PI. I, fig. 5. 



The abdomen has eight distinct segments on the dorsal aspect and but 

 seven on the ventral, the first or subcoxal segment not being apparent 

 here, probably from the less extended condition of the abdomen. 



The two specimens before me which are without any doubt the females 

 of £. pretiosus Lee, show a slight amount of variation. The specimen 

 in my cabinet from which fig. 5 was drawn has the thorax somewhat 

 more convex and the depressions of the thorax well marked, the elytral 

 striae quite deep and the intervals convex. In Dr. Leconte's specimen 

 the thorax more closely resembles that of the male, the striae are feebler 

 especially at base and the intervals less convex. 



The antennae show the most important difierences. In my specimen 

 the penultimate joint alone has the anterior angle prolonged, while in the 

 other specimen (fig. 5 a), this joint and the three which precede are acute 

 in front and are about intermediate in structure between figure 5 and 

 that of E. lautus. 



Two specimens froip the coast region of Cal., south of San Francisco.
