146 GEO. H. HORN, M. D. 



brownish yellow with a darker vitta extending from the umbone nearly to the tip. 

 Body beneath more sparsely punctate than above, more shining and distinctly 

 seneous. Femora brown, tibiae and tarsi paler. Length .52 inch ; 13 mm. (PI. 4, 

 fig. 14.) 



The head and thorax are darker in color than the elytra, the apex of 

 the thorax being, however, somewhat paler. The body beneath is 

 brownish testaceous with a slight jeneous lustre. 



Closely related to S. laetus, but differing notably in color, somewhat 

 in sculpture, and with much deeper oblitjue impressions on the thorax. 



One specimen kindly given me by my friend Salle, collected by M. 

 Alphonse Thevenet at Mariposa, Cala.

D. £ieContei Thomson. — Typi Buprestidarum, Paris, 1879, p. fi. — Crassa, 

 obesii, convexa. Caput sat profunde et valde eonfertim punctulatum. Prothorax 

 subtrapezoidalis, antice angustior et postice latior, profunde et eonfertim punctatus. 

 Scutellum subrotundatum. Elytra tenuissime et confertissirae granuloso-punotata, 

 obsolete longitudin. 6-costata, apice subacuta. Corpus subtus tenuiter punctatum, 

 Pedes punctis aliquibus impressi. 



Supra bruneo-rufo aureo-viridi repercussa; antennae desunt; corpus subtus 

 viridi-aureum, albo-villosum, pedes clare castanei, nitidi. Long 12.6 mm. 



The above is the description by Thomson of a form which seems from 

 a specimen in my cabinet to apply rather to an immature and somewhat 

 distorted specimen than to a valid species.

T. laetifica n. sp. — Form elongate, subdepressed. entirely brilliant metallic 

 green, shining. Front moderately convex, coarsely, deeply and closely punctate. 

 Thorax about one-third wider than long, slightly wider at base, sides regularly

 thirds, apex truncate, base bisinuate, hind angles distinct but rather obtuse; disc 

 moderately convex, median line slightly impressed posteriorly, surface with coarse 

 punctures, sparsely and irregularly placed, coarser near the sides and closer near 

 the front angles. Elytra as wide as the thorax at base, sides parallel, gradually 

 nan-owed at apical third, the margin slightly serrate near the apex, the tip trun- 

 cate and serrulate: surface striate, strise coarsely not closely punctate, intervals 

 fiat with a single series of fine punctures. Prosternum coarsely punctured, the 

 flanks very coarsely but not closely. Metasternum sparsely at middle, densely at 

 the sides. Abdomen coarsely punctured, the third and fourth segments more 

 finely and closely, the fifth more densely. Length .64 inch ; 16 mm. 



A smaller species than our other two and more convex and differently 

 colored. 



Kindly given me by Mr. A. S. Fuller, who obtained it from Texas.
