Dec, ig 1 9-] Shaeffer: Notes ON ClIRYSOMELID.-E. 329 



This species differs from brunnea and varieties in having the 

 upper surface shining and dark with distinct metallic tint and the 

 intervals scarcely raised, except at apex. A specimen taken by my- 

 self at the same locality in August is apparently partly immature and 

 has the elytral punctuation finer than in the type specimen. 



Colaspis brunnea var. viriditincta new var. 



Form and size of C. brunnea; head and prothorax metallic green and 

 cupreous ; elytra yellowish testaceous, scutellum, base narrowly, lateral margin, 

 and generally the punctures metallic green ; abdomen beneath with metallic 

 tint; legs flavous, hind femora black at tip; palpi and antenna flavous, except 

 the seventh and the two last joints, which are black. Head relatively more 

 closely punctate than in var. costipennis ; punctures at sides above the eyes 

 more or less confluent. Prothorax as in var. costipennis. Elytra with seven, 

 more or less distinct costiform intervals. Length 4.5 mm. 



Douglas, Arizona ( F. H. Snow). 



This form differs from var. costipennis, which also has a bright 

 metallic head and prothorax, in having seven, more or less distinct 

 elytral costse. 



Nodonota texana new species. 



Oblong, bronze, surface alutaceous and moderately shining. Head mod- 

 erately coarsely punctate, punctures a little finer and sparser above ; clypeus 

 not contracted. Antennae rufo-testaceous, the outer joints piceous at apex. 

 Prothorax a little more than twice as wide as long, sides arcuately narrowing 

 from base to apex ; basal and apical angles subacute ; surface very distinctly 

 alutaceous and moderately coarsely punctate, punctures scarcely denser at 

 sides than on disk. Elytra irregularly punctate ; punctures a little coarser than 

 on the prothorax, but gradually finer towards apex, where they are less con- 

 fused ; umbo prominent and prolonged posteriorly with a distinct impression 

 internally. Body below alutaceous; propleuras sparsely punctate; abdomen 

 sparsely punctate. Legs rufo-testaceous. Length 3.25 mm. 



Brownsville, Texas. 



I have taken only a single specimen, a female, of this species, 

 which I had placed doubtfully with puncticolUs. It is, however, nar- 

 rower, more elongate and less convex than the latter and the punc- 

 tures of the prothorax are not substrigose. Another specimen, with- 

 out tarsi, is in the Dietz collection from " Texas," which is probably 

 a male. It is a little more shining, prothorax more finely alutaceous 

 and the umbo, though moderately prominent, is not prolonged 

 posteriorly.
