the sides yellow from base to apex, the inner margin of the yellow border sending 

 projections to the fourth stria near the base, at the middle and at the apical third, that 

 at the middle being broadest. Front feebly impressed, vertical carina indistinct. 

 Thorax a little more than twice as wide as long, sides nearly evenly, rather strongly 

 rounded from base to apex ; widest at middle, where it is just perceptibly wider than 

 the elytra ; lateral margin visible from above except posteriorly ; surface evenly not 

 densely punctate on the disk, more coarsely and densely at the sides. Elytra nearly 

 parallel in basal three-fifths, then acutely narrowed : strial punctures moderate, finer 

 on the disk as usual, fifth interval somewhat elevated. Prosternal margin nearly 

 straight in front ; abdomen rather finely, closely punctate, the basal and terminal seg- 

 ments less closely at middle, and somewhat more coarsely ; last ventral without apical 

 plate. Length, II mm., .44 inch. 



Habitat: Arizona. A single specimen in the Horn collection. 



A. daggetti, sp. nov. 



Form rather slender, elongate, feebly depressed, black with faint tinge of blue ; 

 erect hairs sparse, brownish, intermixed with paler at sides. Thorax with sides yel- 

 low in basal two thirds, elytra each with basal and apical spot, and about five inter- 

 mediate more or less irregular transverse fascite, which do not reach the suture and 

 are more or less confluent along the margin. Head closely punctate, deeply im- 

 pressed, vertical carina distinct. Thorax scarcely twice as wide as long, widest a 

 little behind the middle, sides broadly rounded, base not much wider than apex ; sur- 

 face rather closely evenly punctate, impressions moderate ; lateral margin narrow, not 

 distinctly visible posteriorly from above. Elytra not wider than the thora.K, gradually 

 feebly narrowed to apical third, strial punctures rather fine, intervals flat on the disk, 

 convex at sides, the outer three each bearing in a little more than apical half a row of 

 acute tubercles, which are most pronounced on the outer interval, and quite conceal 

 the usual serration of the margin when viewed from above. Beneath clothed with 

 rather sparse grayish hairs ; prosternum emarginate in front, abdomen moderately 

 finely, not densely punctate, last ventral with broad apical plate, its free edge thin 

 and broadly evenly rounded. Length, 8-1 1 mm., .32-. 44 inch. 



Habitat: Arizona (Tucson and Fort Hiiachuca). Eight examples; 

 collections of Daggett, Fuchs, and National Museum. 



A very pretty and graceful species which I take pleasure in naming 

 in honor of Mr. F. S. Daggett, to whom I am indebted for the speci- 

 mens in my cabinet. The tuberculate elytral intervals readily dis- 

 tinguish it from any other species known to me.

At once known among the members of this group by the rather 

 broad reflexed thoracic margin, which is plainly visible throughout 

 from above. Scalaris is the only other species with the thoracic mar- 

 gin similarly visible, but it is here much narrower and not reflexed, 

 while the form is stouter and the markings quite diff'erent. Decipiens re- 

 sembles more closely amabilis and opacula of the Sinuata^ than any species
