common C. viridis, with the punctures in the rows of the elytra rather 

 larger, and the interstices less finely rugous. The under surface is metallic 

 black, the legs black, with the outer half of the tibia? and tarsi obscure testa- 

 ceous in one specimen ; in another they are entirely black. 



102. Chrysomela (Phsedon) prasinella, supra obscure viridi-aenea, ovalis 

 modice convexa, thorace sequaliter inodice punctato, elytris punctulatis, punc- 

 tis vix majoribus striatim digestis. Long. *18. 



Oregon, Mr. Murray. Less convex than the preceding, and less rounded 

 than C. viridis; differs from both by the middle of the thorax being scarcely 

 less punctured than the sides, and the intervals between the rows of punc- 

 tures of the elytra being covered with scattered punctures scarcely smaller 

 than those of the rows. 



103. Haltica r e'c t i c o 1 1 i s, elongata, supra asneo-fusca, pube flava sub- 

 hispida, thorace latitudine paulo longiore, lateribus serrulatis late rotundatis, 

 angulis posticis rectis, anticis prominulis, modice convexo, grosse punctato, 

 sulco basali transverso profundo, elytris oblongis, thorace baud latioribus 

 striis autice fortiter postice subtiliter punctatis, interstitiis punctulatis ; subtus 

 nigra, an tennis pedibusque rufis. Long. "12. 



California, Mr. Murray. The western representative of our H. forticor- 

 n i s ///. (? copalina Fabr.), though very different from that species. 



104. Haltica (Crepidodera) s e m i n u 1 u m, breviter ovata, convexa, nigro- 

 senea, cinereo-pubescens, capite convexo fere Levi, thorace transverso, convexo, 

 antrorsum angustato, basi medio producto, fortiter parce punctato, suleo 

 basali transverso profundo, elytris ante medium dorso impressis, striis e punctis 

 majusculis compositis, interstitiis fere kevibus ; subtus nigra, antennis pedi- 

 busque flavo-testaceis, femoribus nigro-piceis. Long. "09. 



California, Mr. Murray. 



105. Haltica (Crepidodera) m a n c ul a, ovata, convexa, nigro-senea, glabra, 

 capite parce grosse punctato, thorace transverso, convexo, antrorsum angus- 

 tato, angulis anticis rotundatis paulo prominulis, parce punctato, sulco trans- 

 verso postice fere obliterata, striola brevi profunda utrinque notato, elytris 

 striato-punctatis, punctis antice majoribus, apice obscure testaceis, subtus 

 nigra, antennarum basi, tibiis anticis apice, tarsisque piceis. Long. '10. 



East of Fort Colville, Mr. Gibbs. Remarkable for the usual transverse 

 furrow of the thorax being almost entirely wanting. 



106. Galleruca car bo, atra opaca, breviter cinereo-pubescens, thorace 

 transverso, antrorsum angustato, lateribus rotundatis, angulis anticis paulo 

 prominulis, punctato, subcanaliculato, dorso vage biimpresso, elytris parce 

 punctatis, sulco marginali lato haud profundo. Long. *20 "22. 



East of Fort Colville, Mr. Gibbs. Resembles G. Sagittariae, but is 

 entirely black, and the thorax is more rounded on the sides. 



107. Triplax an tic a, elongata ovalis, nigra nitida, capite thoraceque 

 haud dense punctatis, hoc transverso antrorsum paulo angustato, lateribus 

 parum rotundatis, elytris subtilius striato-punctatis, interstitiis vix obsolete 

 punctulatis, basi anguste indeterminate rufis, antennis palpis pedibusque 

 rufis, illis clava nigra. Long. -16. 



Sinyak water depot, Mr. Gibbs. Totally distinct from any other of our 

 elongate species, which constitute the genuine group of the genus. 



108. Hippodamia spuria, ovalis, longiuscula, thorace nigro, limbo omni 

 angusto lineisque duabus discoidalibus albis, elytris pallide fulvis, macula 

 communi scutellari elongata, altera humerali, tribusque utrinque pone me- 

 dium 2, 1, positis nigris, ssepe deficientibus, his nonnunquam varie conflu- 

 entibus, angulo suturali rotundata, subtus nigia epimeris mediis et posticis
