286 PROCEEDINGS OP THE ACADEMY OF 



both of thorax and elytra, as well as by the markings of the latter. The inner 

 curved stripe extends from one-sixth from the base to one-third from the apex ; 

 the outer one is contiguous to it, connected with a humeral spot, and abbre- 

 viated behind at the middle. 



Haltica aeruginosa, oblongo-ovalis, modice convexa, obscure cuprea, 

 subnitida, thorace convexo, subtilissime punctulato, linea transversa postica 

 obsoleta, antrorsum subangustato, lateribus parum rotundatis, elytris thorace 

 latioribus, dense punctulatis. Long. *16. 



San Francisco, one specimen. 



Haltica e v i c t a , oblongo-ovalis, minus convexa, cuprea, nitida, thorace 

 punctulato, linea transversa postica subtili distincta, versus angulos posticos 

 foveato, antrorsum subangustato, lateribus parum rotundatis, elytris thorace 

 latioribus, subtiliter punctatis striis nonnullis obsoletissimis, sulcoque versus 

 latera parum distincto. Long. -20. 



Sacramento, one specimen ; Mr. Rath von. 



Haltica t i n c t a , oblongo-ovalis, modice convexa, nigro-aenea nitida, thorace 

 convexo, parce obsolete punctulato, linea transversa postica tenui, antrorsum 

 angustato, lateribus paulo rotundatis, elytris thorace latioribus, sat dense 

 punctatis. Long. *20 '22. 



Table Mountain, below San Francisco, Mr. Davidson : two specimens. These 

 three species belong to the division Grraptodera Chevr. 



Dibolia o v a t a , ovata, convexa, nigro-aenea, nitida, subtiliter punctulata, 

 elytris seriebus punctorum subtilibus postice haud distinctis, antennis nigris 

 basi testaceis, tibiis tarsisque anterioribus testaceis, femoribus obscuris. Long. 

 12. 



One specimen, Punto de los Reyes. The posterior thighs are black, and the 

 tibiae and tarsi dark brown. Broader and more ovate than D. aerea Mels., 

 with the rows of punctures of the elytra very fine, not impressed, and oblite- 

 rated behind. 



Luperus smaragdinus, elongatus, cyaneo-viridis, antennis nigris 

 basi fuscis, thorace convexo, quadrato, lateribus paulo rotundatis, anticis 

 prominulis rotundatis, parce subtiliter punctulato, elytris sat dense punctula- 

 tis. Long. -23. 



Punto de los Reyes, three specimens, Mr. Davidson. Resembles L. varipes 

 Lee. but differs by the entirely black legs, and by the thorax being much less 

 densely punctulate. The second and third joints of the antennae together are 

 equal to the fourth ; the third is one half longer than the second. 



Coccinella melanopleura, ovalis, modice convexa, capite thoraceque 

 haud dense punctulatis, illo maculis duabus albis, hoc limbo antico, lateribus 

 late (macula nigra inclusa) lineolaapicali, maculisque duabus basalibus albis, 

 scutello nigro, elytris ferrugineis, confertim subtiliter punctatis ; subtus nigra, 

 tibiis tarsisque fusco-testaceis. Long. - 21. 



Table Mountain, Mr. Davidson, one specimen. Closely resembles the varie- 

 ties of C. p i c t a, with immaculate el} r tra, but differs by the body being entirely 

 black beneath, and by the elytra being more finely punctured. It is probable 

 that varieties will occur with white thorax having black spots, and also with 

 elytral markings. 



Coccinella b a r d a , hemisphaerica, capite punctulato, albo, postice nigro, 

 thorace parce punctulato, nigro, macula magna utrinque, limboque antico 

 albis, elytris subtiliter dense punctatis, ferrugineis, fascia transversa communi 

 pone basin nigris, scutello, sutnraque ad basin nigris ; subtus nigra, epimeris 

 albis. Long. -21. 



Punto de los Reyes, one specimen, Mr. Davidson. There is no trace of any 

 posterior spots on the elytra : the band stops on the humerus, and is slightly 

 widened there.
