COLEOPTERA OF SOUTHERN CALIFORNIA. 233 



41. Scymnus taedatus, sp. nov. 



Oval, thoracic and elytral margins not continuous; dark brown; head, 

 thorax and tip of abdomen yellowish; the thorax with faint piceous 

 clouds at the middle and before the scutellum; elytra each with a small 

 spot before the middle and nearer the suture, another a little larger and 

 posterior to it, and more or less connected with an indefinite apical space, 

 pale. Head evidently punctate; thorax lightly but distinctly punctate at 

 middle, more finely laterally; sides nearly straight in basal two-thirds. 

 Elytra less finely but not closely punctate. Prosternal elevated lines 

 distinct; mesocoxal arcs joining the lateral suture a little before the mid- 

 dle; inetacoxal arc incomplete, joining the first ventral suture. Abdomen 

 finely punctate, and with six distinct segments. 



Length, nearly 1.5 mm. 



Found in the Sierras of Southern California. Several 

 specimens beaten from Pinus ponderosa. 



By the metacoxal lines this species belongs to Dr. 

 Horn's Group A, and may follow 8. bigemmeus. There 

 are no obvious sexual differences. 



42. Scymnus megacephalus, sp. nov. 



Oblong, obtusely rounded before and behind, moderately convex, uni- 

 formly rufotestaceous throughout. Pubescence rather short, flavocinere- 

 ous, not very conspicuous but slightly holosericeus in aspect owing to 

 the arrangement of the hairs. Head very large, the eyes almost entirely 

 exposed and separated on the front by distinctly more than twice their 

 own width; punctuation rather fine, the punctures separated by from one 

 to two times their own diameters. Prothorax less than twice as wide as 

 long, the sides evenly, moderately arcuate, the apex evidently though not 

 very much narrower than the base; surface punctate similarly to the 

 head, the disposition and size of the punctures nearly uniform through- 

 out; base not sinuate each side of the middle, the marginal line strictly 

 basal before the scutellum. Elytra oblong, slightly wider than the pro- 

 thorax, the sides very feebly arcuate, and parallel to a point far behind the 

 middle; punctuation somewhat sparser than on the head and prothorax. 

 Scutellum equilateral, larger than usual. Prosternal ridges strong and 

 entire; mesosternum closely, rather coarsely punctate; abdomen less 

 coarsely and closely punctate than the metasternum. Postcoxal arcs of 

 the metasternum incomplete externally, though nearly reaching the 

 suture; those of the first ventral obliterated externally, the lines reaching 

 about to the apical fourth of the segment and scarcely visibly recurved, 

 the plates punctate like the rest of the segment. Femora stout; claws
