AMERICAN COLEOPTERA. 15 



Specimens of this species occur with a small, lateral, thoracic spot, 

 sometimes on one side only. 



Occurs over nearly our entire country east of the Rocky Mts. 



A. flaTOSticta. n. sp. — (PL I, fig. Ifi.) Form subdepressed, surface with 

 cupreous lustre and with few erect black hairs. Head coarsely and deeply 

 punptured, front with distinct impression, vertex not carinate. Thorax more 

 than, twice as wide as long, apex emarginate, base truncate, sides moderately 

 arcuate, margin distinctly visible from above; disc with moderate median 

 triangular impression, lateral oblique impressions rather deep; surface with 

 coarse, deep sparsely placed punctures, denser at the sides, surface unicolored. 

 Elytra as wide at base as the thorax, sides gradually converging from base, 

 more rapidly at ai)ical third and rather coarsely serrate, unibone rather feeble; 

 disc feebly convex, sti iate, striae rather coarsely and serrately punctured, inter- 

 vals slightly convex and with a single series of fine punctures; surface ornate 

 with yellow as follows : an irregular spot at middle of base, a lateral stripe 

 from humerus to middle with a branch toward the suture, posteriorly two 

 interrupted fascise. Body beneath bronzed, shining, with very short, sparse 

 pubescence. Prosternum as in conne.va. Abdomen rather coarsely and sparsely 

 punctured, last ventral with distinct double apical margin. Length .28 — .36 

 inch ; 7 — 9 mm. 



The elytral markings of this species somewhat resemble certain 

 forms of pufche/la. Tlie nau)e given is an unpublished one of Sturm 

 found attached to it in some European cabinets. The same species 

 was mentioned in the List by Dr. Leconte as croceonotata Gory. 



Occurs in Lower California (Peninsula), collected by Mr. John 

 Xantus de Vesey. 



A. Dohriii, n. sp. — ;P1. I, fig. 21.) Form moderately depressed, surface 

 shining, bronzed and sparsely clothed with black hair, elytra with three mar- 

 ginal spots behind the middle, the central spot larger. Head coarsely and 

 moderately densely punctured, front convex, vertex with feeble trace of carina. 

 Thorax unicolored, twice as wide as long, apex moderately emarginate, base 

 truncate, sides feebly arcuate, margin narrow, visible from above for a short 

 distance in front, posteriorly inferior; disc with vague median impression and 

 a shallow fovea on each side at base; surface coar-sely but not densely punc- 

 tured. Elytra as wide as the thorax, sides subparallel. gradually narrowed at 

 apical third which is serrate, umbone moderate; disc depressed, surface striate, 

 striee deeper at sides and a|)ex. |)unetured with inoderata, not closely placed 

 punctures, intervals flat with a single series of moderate punctures. Body 

 beneath bronzed, shining, sparsely hairy. Prosternum very sparsely punctured 

 at middle, at sides moderately and coarsely. Abdomen very sparsely punctured, 

 more densely at the sides of the first segment; last ventral without trace of 

 subapical carina. Length .32 inch; 8 mm. 



The elytral markings consist of three reddish spots on the lateral 

 margin, the first about at the middle, the second at three-fourths ex- 

 tending inwards to the middle of the elytra, the third between this 

 and the apex. This species resembles considerably one of the next
