Rev. H. Clark on Dejean's Genus Ccelomera. 325 



filiforraes, corpus longitudine penitus sequantes, art. 1° subgloboso, 

 2° minore, 3° primum sequante, 4° et 5° tertium superantibus et sub- 

 aequalibus, 6°-ll m subsequalibus. Pedes elongati, tarsorum art. 

 basali longitudine art. 2 m superante, unguiculis utrinque bifidis. 



Nestinus approaches Coraia in the length of the antenna and 

 the relative length of the basal joint of the tarsus ; it differs from 

 that genus in the slender form of the autennse, in the fourth 

 joint being longer than the third, and also in the form of the 

 thorax. The known species that represent the genus are three 

 or four in number, and all from Mexico.

Guatemala.

 tata vel seneo- vel aureo-metallescentia ; antenna nigrse ; pedes

Long. corp. lin. 4^-5^ ; lat. lin. 2-2f . 



Mexico. I possess an example from California, which pre- 

 sents no variation from the Mexican form. 



3. iV. incertus. 



N. subparallelus, punctatus, lsevis, flavus ; elytris fusco-viridescenti- 

 bus, thorace fusco-flavo, antennis fuscis ; caput crebre punctatum, 

 flavum, basi late nigra ; thorax transversus, latus, subdepressus, 

 planus, leevis, angulis posticis rotundatis, crebre punctatus, fusco- 

 flavus ; scutellum leviter punctatum, flavum ; elytra parallela, 

 lsevia, crebre punctata ; antennae robustte, nigrse ; pedes rufo-flavi, 

 tarsis fuscis ; corpus subtus rufo-flavum. 



Long. corp. lin. 6 ; lat. lin. 3. 



A somewhat aberrant form of Nestinus, but which agrees in 

 the main with the generic diagnosis. . It is possible that here- 

 after it may constitute a separate genus.
