Studies Amongst the Coccinellidae, No. 2, (Col.). 
By F. W. NuNENMACHER, Piedmont, California. 
Since my last paper on Coccinellidae* several friends and 
correspondents have sent me material in various genera in- 
cluding several species new to science, and as some of these 
are of considerable interest it seems worth while to publish 
the following descriptions at this time: 
Genus PSYLLOBORA Mulsant. 
Psyllobora koebelei n. sp. 
$.—Color: Whitish yellow with chocolate brown markings disposed 
as follows: Pronotum with the five common discal spots, each elytron 
with one juxta-scutellar and one median basal dot, one marginal small 
dot placed a little before the middle, and one irregular blotch roughly 
quadrate in form, placed its own width from the margin and close to 
the suture and rather behind the middle. Mouth parts testaceous; 
ventral surface black except mesothoracic episterna, which are white 
and last four ventral segments, which are testaceous, as are the legs. 
Form convex, subovate; head, impunctate; pronotum very finely and 
sparsely punctured; elytra moderately coarsely punctured; ventral sur- 
jace, sternum moderately coarsely punctured; abdomen smooth. 
Length, 2.25 mm. Width, 2 mm. 
Type— ¢ in my collection. 
Type locality—Nogales, Santa Cruz Co., Ariz. vi. 02. 
(Koebele) 
This species, which feeds on the scale infesting mistletoe, 
comes nearest to P. luctuosa Muls., from which it can readily 
be told by the elytral design. The type was kindly given me 
by Mr. A. Koebele in whose collection there are several speci- 
mens. According to his observations (No. 2426), this species, 
when alive, has a ground color of beautiful shimmering sil- 
very green. 
Genus AXION Mulsant. 
Axion incompletus n. sp. 
é.—Color: Head light ferrugineous, pronotum and elytra black, 
the former with the anterior angles ferrugineous and a beaded line of. 
the same color along the entire anterior margin, each elytron with a 
median double coalescing spot at the callus, nearer the margin than the 
suture, the shape of this spot being obliquely and roundly oblong with 
a prolongation towards the base of the elytron; ventral surface uni-
