A. morbosa, sp. nov. 



Moderately robust, somewhat depressed, elytra slightly, pronotum and under sur- 

 face rather strongly bronzed, entirely without markings ; erect hairs whitish beneath, 

 dark and paler intermixed above. Head with indistinct vertical carina, thorax twice 

 as broad as long, very slightly wider before the basal angles, moderately rounded and 

 narrowed anteriorly, side margin posteriorly not visible from above ; rather closely 

 punctate, more densely at sides. Elytra as wide, or very nearly so, as the thorax, 

 humeri not prominent, sides very slightly convergent to a little behind the middle,, 

 then more rapidly to apex ; striae and punctures moderate. Prosternum with front 

 margin retracted and slightly but distinctly sinuate. Abdomen rather strongly but 

 not closely punctate, last segment with very small apical plate. Length, 9 mm., 

 .36 inch. 



Habitat: Two examples, Los Angeles Co., California, collections 

 of Dr. Fenyes and myself. 



Structurally very close to labyrintliica and possibly an immaculate 

 variety of that species, but in the many specimens of the latter that I 

 have seen, there is no tendency whatever toward even a noticeable re- 

 duction of the yellow markings.

The thorax is said to be unicolored in the description and it is 

 usually so in specimens from Lower California. In those from south- 

 ern California the marginal spot is about as often present as absent. 

 The apical ventral plate is thin with posterior edge nearly squarely 

 truncate. Length, 7-10.3 mm., .28-. 41 inch. 



Habitat: The twenty-one examples before me range from Cape 

 San Lucas as far north as Riverside, Cal. It was taken in some num- 

 bers in San Diego Co., by Mr. Coquillett, and is apparently a common 

 species in the Peninsula.

Unfjuestionably distinct from connexa in my opinion, the doubts 

 expressed by Horn arising from the including under this name the 

 form which I have separated as labyrintliica. See remarks under laby- 

 rintJiica. Length, 5-9 mm., .20— .36 inch. 



Habitat: Our commonest Californian species, occurring nearly 

 everywhere in the mountains and foothills from San Diego to Shasta. 

 I have never seen typical examples from east of the Sierras, though it 

 is not unlikely that it extends into Nevada in the Lake Tahoe region. 

 Horn gives also L^tah, but his specimens from that locality are laby- 

 rinthica.
