Fort Tejon, California, Mr. Ulke's collection. This species, of which I have 

 seen but a single specimen, differs from P. Schaumii chiefly in the form of 

 the thorax, which is comparatively broader and more rounded on the sides.

 Lampyrus splendidula Linn., &c, &c, (vide Kiesenw. loc. cit.) 



A male of this European species was found by Mr. P. R. Uhler, near Balti- 

 more, Md., and kindly presented to me. It does not yet deserve a place in 

 our fauna. 



PODABRUS Westwood. 



P. Pattoni, niger nitidus pubescens, capite parce punctulato, thorace 

 impunctato, quadrato, latitudine baud longiore, lateribus paulo uridulatis, 

 angulis anticis oblique truncatis, posticis acutis prominulis, laete flavo mar- 

 gine antico et postico nigricante, dorso postice bigibboso et medio excavato, 

 margine laterali angusto reflexo ; elytris baud dense minus subtiliter rugosis; 

 antennarum articulo 3io praecedente paulo longiore et 4to paulo breviore, un- 

 guiculis appendiculatis. Long. 6-5 mm. 



I found two specimens of this pretty elongate species in Lycoming County, 

 Pa. It gives me much pleasure in dedicating it to the Hon. B. F. Patton, to 

 commemorate his value as a friend, as well as his great interest in the object 

 of the journey during which the specimens were collected. 



It resembles in form P. laevicollis, but may be distinguished from the 

 variety of that species with yellow thorax by the punctures of the head being 

 less fine and less dense, and by the rugosities of the elytra being more 

 obvious ; the thorax is a little broader, the outline of the sides is not concave, 

 but slightly convex, and the lateral margin is very distinctly depressed and 

 slightly reflexed ; the antennae and feet are black, tlie first and second joints 

 of the former are pale beneath ; the palpi are pale, with the tip black. P. 

 simplex Couper, Canadian Nat., 1865, (52, is also related, but the thorax 

 is comparatively smaller and less polished, and the base of antennae, the 

 mouth and the feet are yellow. 



Descriptions of some new CICINDELID.ffi from the Pacific Coast of the 



United States. 



BY GEO. H. HORN, M. D. 



The insects described in the present paper form part of a collection brought 

 by myself from the west coast, accumulated during a four years' residence in 

 California and the adjoining territories. Believing it important to make known 

 the existence of these species, the descriptions are here given in advance of a 

 more extended memoir on the Coleoptera of the Pacific slope of our country. 



OMUS Esch. 



1 33 v i s ater, subopacus, thorace latitudine baud breviore, trapezoides, 

 modice convexo, ad basin modice intricato-rugoso ; elytris sublaevibus punc- 

 tisque obsoletis irregulariter impressis. Long. - 75. 



This species differs from all the others of the genus in being almost entirely' 

 smooth and subopaque. The elytra are regularly oval, as in californicus, ex- 

 hibiting a few almost obsolete punctures irregularly placed like the foveas in
