may be present only at apex ; these blotches, if longitudinally conflu- 

 ent are never regular in outline as the vittae in purpureovitta, being 

 nearly the same as in hicana. 



Chrysobothris beyeri, new species. 



Form oi femora ta, but slightly more convex, cupreo-Eeneous, thorax more cu- 

 preous. Head transversely strigosely punctured, at top an arcuate carina, at middle 

 between this and the clypeus ivfo smooth callosities ; antenna cupreous, gradually more 

 slender to tip, third joint a little shorter than the next two ; clypeus broadly emargi- 

 nate, arcuate each side. Thorax twice as broad as long, narrowed at apex and base, 

 slightly arcuate at sides ; disk feebly convex, median sulcus distinct, on each side 

 near margin a shallow rounded injpression, surface transversely strigose, not coarsely 

 punctured. Elytra a little wider than the thorax, parallel to nearly apical third, then 

 gradually narrowing to apex, apices obtuse, sides not strongly serrate ; the subsutural 

 costa more elevated from a little before middle to apex, the second costa elevated 

 from base to apex but interrupted at basal third, the third costa more feeble and 

 interrupted at a little behind middle by a fovea, which is more finely sculptured than 

 the rest of surface, the fourth costa near margin entire ; surface sculpture rugose, 

 punctuation somewhat sparse, basal and humeral impressions feeble. Body beneath 

 coarsely punctured, each ventral segment at side with a distinct callosity; pro- 

 sternum in front very feebly arcuate ; anterior femora with a broad tooth, serrulate on 

 iis margin, last ventral with serrulate margin. Length, 11-12 mm. 



Male. — • Prosternum moderately densely punctate, and finely pubescent ; anterior 

 tibiK arcuate, broadly dilated at tip, middle tibire straight, slightly bent at apex, hind 

 tibi?e straight ; last ventral segment, broadly emarginate, last dorsal truncate. 



Female. — Prosternum as in the male, anterior tibiae slightly arcuate, middle and 

 hind tibiae straight ; last ventral segment not as broadly emarginate as in the male, 

 more semicircular. 



San Felipe, Lower California ; four specimens in the Museum of the 

 Brooklyn Institute from Mr. G. Beyer in whose honor I have named 

 this species as a slight recognition of the many favors received. C. 

 beyeri resembles texaiia in color and sculpture but very distinct from 

 it by the different emargination of the clypeus and last ventral seg- 

 ment and the much more feeble prosternal lobe, the anterior tibiae of 

 the male in this species are not sintiate before the dilatation as is the 

 case in texaiia. As I am informed by Mr. Beyer this species is very 

 abundant on willow in the dry season in May and June. 



Chrysobothris peninsularis, new species. 



Form o{ Jloricola, color dark bronze; antennae short, metallic green, slightly 

 narrowing to apex, third joint as long as the next two ; clypeus very broad, but 

 shallow emarginate at middle. Thorax twice as wide as long, sides nearly parallel, 

 very slightly narrower at base, more rounded and narrowed at apex than at base, disk 

 feebly convex, a vague median impression and very obsolete, rounded impression at 

 sides ; punctuation sparser at middle, coarse and confluent at sides. Elytra very little
