16 GEO. H. HORN, M. D. 



group, mariposa, wliich is however bright blue and has a diflferent 

 prosternum. 



I dedicate this species with great pleasure to Dr. C. A. Dohrn of 

 Stettin, by whom it was sent with a number of other species, for 

 naming. There is also a second specimen in Mr. Ulke's cabinet. 



Occurs in California. 



A. decipiens, Lee. — (PI. I, fig. 17.) Form moderately robust, subde- 

 pressed, surface distinctly bronzed and with erect black hairs. Head coarsely 

 and densely punctured, front impressed, vertex with distinct carina. Thorax 

 more than twice as wide as long, very little wider at base than apex, apex 

 emarginate base truncate, sides rather strongly arcuate, margin moderately 

 wide, distinctly reflexed and visible in its entire extent from above; disc with 

 feeble median triangular impression and moderately deep lateral fovese ; sur- 

 face coarsely, deeply and moderately densely punctured, nearly equally over 

 the entire surface, sides rather broadly yellow. Elytra narrower at base than 

 the thorax, umbone moderate, sides gradually and at apical third more rapidly 

 converging to apex and serrate; disc feebly convex, striate, (striae feeble at 

 middle near base), strise rather coarsely punctured, intervals at apex and sides 

 convex and uniseriately punctulate; surface distinctly bronzed and intricately 

 marked with yellow. Body beneath bronzed, shining, s{)arsely hairy. Pro- 

 sternum as in connexa. Abdomen rather coarsely but sparsely punctured, last 

 ventral with distinct double apical margin. Length .42 inch; 10.5 mm. 



I have seen but one specimen of this species brought by Dr. Coues 

 from Arizona. 



A. Tariegata, Lee. — (PI. I, fig. 19.) Form moderately robust, disc nearly 

 flat, surface faintly bronzed, with erect black hair, elytra with three yellow 

 bands and an apical spot. Head coarsely punctured, front convex, vertex with 

 fine carina. Thorax margined with yellow at the sides, twice as wide as long, 

 apex emarginate, base truncate, sides moderately arcuate and when viewed 

 directly from above slightly sinuate posteriorly, margin very narrow, not visi- 

 ble from above, inferior posteriorly; disc with moderate median triangular 

 impression, and with oblique lateral impressions foveate at base ; surface opaque, 

 densely and coarsely punctured becoming cribrate at the sides. Elytra as wide 

 as thorax, sides parallel and at apical third gradually narrowed to tip; disc 

 flat, striate, strise coarsely and closely punctured, intervals flat, each with a 

 row of moderately coarse punctures; surface bronzed with three yellow bands 

 nearly transverse and of variable width and a subapical spot. Body beneath 

 very dark bronze, sparsely clothed with greyish hair. Prosternum as in con- 

 nexa. Abdomen sparsely punctate last ventral without trace of subapical 

 carina. Length .36 inch; 9 mm. 



This species bears considerable superficial resemblance to tuta of 

 the preceding group but is readily known by the form of the pro- 

 sternum and the entire absence of any subapical carina to the last 

 ventral. 



Several specimens were collected by Dr. Palmer at St. George, 

 Utah.
