Vol. VII] GIFFARD— CALIFORNIA HEMIPTERA 259 



the discoidal area brown from before the middle ; apex of the elytra 

 with a broad transverse band omitting the marginal areoles and connect- 

 ing with a longitudinal cloud on the overlapping sutural areas ; pronotal 

 carina white with the usual fuscous vitta. 



Described from numerous examples taken about San Diego 

 during May, July, October and November, and three exam- 

 ples taken by Mr. Giffard at Los Altos, July 26, 1916. 



This form may best be distinguished by its having the dis- 

 coidal cyst of the elytra large, covering most of the discoidal 

 area. C. hiairvata Uhl. is very similar to this but it is 

 smaller, has the discoidal bullae of the elytra smaller, the 

 costa more deeply arcuated and the colors paler with the 

 elytral vittse faint. 



Holotype (No. 331). male, from San Diego Co.. in the 

 museum of the California Academy of Sciences. 



Allotype, female, from San Diego Co., in collection of 

 the author. 



Paratypes, in the author's collection and in that of Mr. 

 Gififard. 



CorythucJia coclata Uhl is common on Ceanothus in San 

 Diego Co., from March to May; Mr. Fordyce Grinnell 

 has taken it at Pasadena in June, and Dr. J. C. Bradley has 

 sent me specimens taken at Felton. Calif., in May, and at 

 Palo Alto in September. Prof. H. F. Wickham has sent me 

 a good series of Corythucha hispida Uhl taken at the Grand 

 Canyon of the Colorado in Arizona. 



65. Physatocheila ornata, new species 



Form of brevirostris, a little broader than plexa; pale cinnamon varied 

 with brown and buff; costal area with two series of irregular areoles. 

 Length 4 mm. 



Antennae more slender than in any of our allied species, the third seg- 

 ment apparently about one-half the thickness of the second, this latter 

 two-thirds as long and as wide at apex as the first, much narrowed bas- 

 ally; fourth clavate, distinctly longer than the first. Reflexed pronotal 

 margins a little narrower than in plexa, leaving a wider area between the 

 conspicuous carinae, the surface as in brevirostris with a vague transverse 

 line between the posterior angles of the reflexed margins behind which 

 the areolae are distinctly larger; in plexa these larger areolae extend for- 

 ward but about half way to the reflexed portion. Costal area with two 

 rows of very irregular areolae, these being more irregular than in plexa. 

 Tip of the rostrum covered in all the specimens before me but appar- 

 ently attaining the apex of the metasternum and little if any surpassing it. 



Color yellowish or more or less fulvous, the elytra and reflexed por- 

 tion of the pronotum cincrous-white ; head black with the spine-like
