52 GEO. H. HORN, M. D. 



Occurs in Oregon and British Columbia. For my specimens I^ara 

 indebted to Mr. H. Ulke. 



E. Tiri<lis n. sp. — Form moderately robust, color above brilliant green. 

 Head densely punctured, brilliant green, with bronze spots, one clypeal, two 

 frontal, one vertical and two occipital; eyes moderately prominent. Thorax 

 slightly broader than the head, broader than long, base and apex equal, sides 

 strongly arcuate in front, basal half suddenly sinuate, hind angles slightly 

 divergent; apical transverse impression moderate, median line finely impressed* 

 surface densely and finely punctured, brilliant green maculate with bronze in 

 the following manner: an apical spot on each side, a small median basal spot, 

 an inverted V-shaped mark, the angle being at the apical margin the ends at 

 the hind angles. Elytra oval, broadest behind the middle, surface very densely 

 and finely punctured without distinctly defined ocellate punctures, surface 

 brilliant metallic green with a sutural bronze space and with three series of 

 elevated highly polished spaces of moderate size and nearly equal, the sutural 

 series of three, the median of four the outer of two. Body beneath green, less 

 brilliant than above, side pieces of thorax rather sparsely punctured intervals 

 smooth. Legs pale with aeneous surface lustre, tips of tibise and femora darker. 

 Length .22 inch ; 5.5 mm. 



This species is peculiar in the form of the thorax, the color of the sur- 

 face and the absence of ocellate foveas. Its position is probably with our 

 smaller species in which the male has three dilated anterior basal joints. 

 One specimen 9 from Mr. A. S. Fuller, collected in California. 



DYSCHIRIUS Bon. 

 I>. Isevirasciatiis n. sp. — Aeneous, shining. Clypeus deeply emarginate, 

 on each side dentate, sides of front lobed, lobes carinate, front transversely 

 broadly impressed. Thorax globose, median line deeply impressed posteriorly. 

 Elytra very deeply striate, strise at base obsolete, at apex deeply impressed, 

 obsoletely punctured and broadly interrupted by two arcuate transverse spaces 

 through which the striae are continued by very fine punctures, sutural and 

 marginal striae entire, basal stria obsolete; third interval with three distinct 

 punctures. Legs and basal joint of antennae pale rufous, hind tibise rather 

 more arcuate than usual. Anterior tibiae bidentate externally, the upper tooth 

 feeble, terminal spur long and moderately arcuate. Length .12 inch; 3 mm. 



The appearance of this species with the unusually deep striae 

 twice broadly interrupted is very peculiar and seemed to me at first 

 a deformity. Its characters, otherwise, define the position it should 

 occupy in the series which is near consobrinus Lee The transverse 

 impression of the front although broad is feeble and the striae at base 

 are obliterated, at apex deeply impressed, and the basal stria entirely 

 wanting; these characters place it with the species mentioned rather 

 than with seneolus, etc. 



I have seen three specimens exactly alike received from Oregon 

 by Mr. H. Ulke. one of them being now in my cabinet through 

 his kindness.
