46 GEO. H. HORN, M. D. 



Third joiut of antennie obviously longer than the second, eighth smaller than 

 seventh; elytra veiy distinctly punctato-striate, the intervals sparsely 



punctate; 4 — 4.5 mm Hainiltoni. 



Third joint of antennte not longer than second. 



Seventh joint of antennae very distinctly larger than the eighth ; elytra in- 

 distinctly punctate in striie ; 2 mm oryptopliagoideiii. 



Seventh joint scarcely larger than the eighth ; elytra with very distinct striae 

 of punctures; 1.5 mm pusi<». 



DEIVDROPHILUS Leach. 



D. CRlif)>rilicii$$ n. sp. — Slightly oblong oval, piceous-black, shining. Head 

 dull, finely indistinctly punctate. Thorax punctate, punctures neither coarse 

 nor close, but finer along the apex at middle. Elytra dull at apex, surface mod- 

 erately closely punctate, but less distinctly near the apex, surface with four im- 

 pressed strife, which decrease in length from the outer to the inner; within the 

 inner stria are two short strife composed of punctures only. Epipleurje and 

 underside of body more or less opaque, sides of metasteruum closely punctate, 

 the middle less so; abdomen alutaceous, moderately closely punctate. Pygidium 

 dull, closely and finely, but indistinctly punctate. Length .12 inch.; 3 mm. 



This species is closely related to punctulabis of the eastern region, 

 hut is of more oblong form, the elytra with the two inner striie of 

 punctures, the pygidium less evidently punctate, and the surface of 

 the elytra more opaque at apical third. 



The species of Dendrophilvs are few in number, and have a close 

 resemblance. This one has been described as an indication of further 

 generic distribution. The measurement is from' the apex of the 

 thorax to apex of elytral suture. 



Occurs in Santa C!lara County, Cal.

The specimens of this genus had become misplaced at the time 

 the preceding notes on Chrysoraelidse were prepared. 



There is hardly a genus of the entire family which is more apt to 

 confuse the student at first sight. With a facies which would sug- 

 gest its position among the Galerucini, it possesses characters in the 

 structure of the mouth parts approximating it to the Sagrini. In 

 all the species the thorax has a moderately deep transverse groove 

 near the base limited by a longitudinal [jlica as in some Halticini 

 and EndomychidcC. 



One species is known to me in our fauna. 



A. purpurea n. sp. — Oblong, parallel ; beneath, legs and antennae piceous, 

 above bluish- or purplish-black, subopaque, head and thorax often reddish-yel- 

 low. Head sparsely punctate at the sides. Thorax about a third wider than 

 long, apex slightly narrower than the base, sides arcuate in front, then oblique
