NORTH AMKErCAX COLEOPTEKA. 283 



In the table given by Chapuis Metaparla should be placed near 

 Noda {■= Nodonota), from which it differs in having the second and 

 third joints of the antennae equal in length and the anterior angles 

 of the thorax not prominent externally. The basal marginal line 

 of the thorax is distinct, but fine. 



M. clytroidesCr., Proc. Acad. 1873, p. 40.— Oblong, nearly parallel, bright 

 green. Antennse three-fourths the length of the body, the basal and outer five 

 joints piceoiis, intermediate joints rufo-testaceons, the outer five joints together 

 longer than the basal six. Head relatively large, surface alutaceons, sparsely 

 punctate; clypens rather deeply, labrnni less emarginate. Thorax transverse, 

 very little narrowed in front, sides regularly arcuate, anterior angles not promi- 

 nent, basal marginal line fine, but distinct; disc convex, surface alutaceons, 

 sparsely but regularly punctate; scutellum oval, broader than long. Elytra but 

 little wider than the thorax at base, surface alutaceous, more coarsely punctate 

 than the thorax, with two vague, smooth interspaces on each side. Body indis- 

 tinctly punctate. Legs rufo-testaceous, sometimes piceo-rufous with the femora 

 more or less bronzed. Length .12 inch. : 3 mm. 



In the males the head is longer than in the female and the jaws 

 more prominent. The first joint of the anterior and middle tarsi is 

 dilated. 



Crotch states that the tibi?e are dentate, but this does not seem to 

 be true. The antennal joints 2-3 are equal in length, 3-4-5 are a 

 little shorter, but inter se equal in length. The outer five joints are 

 more dilated than in any of the nearly allied genera. 



All the specimens examined have been collected in Texas. 



C'HRY^iODIIVA Baly. 



The single species constituting this geiuis in our fauna was de- 

 scribed under the generic name Chalcoparia Crotch (Proc. Acad. 

 1873, p. 39). The reference to the "Check List" of later date is 

 not a valid citation (Lefev. Eumolp.). 



In the synoptic table of genera (loc. cit. p. 33) Crotch erroneously 

 l)laces this genus with those having the thorax lobed behind the eves.

 39; ovataSiiy, Journ. Acad, iii, p. 442; edit. Lee. ii, p. 211. — Broadly oval and 

 convex, surface shining, bronze-blue or bra.ssy. Thoracic punctuation not close, 

 regularly placed, finer than on the elytra. Elytral punctures moderately coarse 

 and deep, not closely placed, and with an evident tendency to form rows. Legs 

 rufo-testaceous. Length .10 inch.; 2.5 mm. 



In the male the first joint of the anterior and middle tai'.>i is di- 

 lated forming an area as large as the next two joints. 



The species of Chrtfsodina seem to be of small size. It is, more- 

 over, as remarked by Mr. Jacoby (Biol. Cent.-Am.), extremely diffi-
