Tejon. I knew not the value of this or the preceding genus, nor the charac- 

 ters upon which they rest : the habitus is sufficient to enable them to be 

 readilj recognized, but future researches will be necessary to establish them 

 fully. 



141. Diabrotica 12 -punctata. 



142. Galleruca guttulata. 143. G. luteocincta. 



144. Microrhopala signaticollis, nigro-cyanea, capite tristriato, thoraee 

 latitudine breviore, antrorsum angustato, lateribiis rectis, parce grosse punc- 

 tato, macula maxima laterali a basi fere ad apicem extensa rufo-flava, elytris 

 thoraee latioribus subparallelis, apice late rotundatia, punctis grossis seriatim 

 positis, seriebus per paria paulo approximatis. Long. - 23. 



Tejon, one specimen. This species has the form, size, and sculpture of Hispa 

 c y a n e a Say, except that the thorax is more sparsely punctured. The 

 lateral yellow spots readily distinguish it from all others seen by me. 



145. Hippodamia punc t ulat a . 146. H. obsoleta. 



147. Mycetina morosa, elongata, nigro-picea nitida, thoraee vix punctu- 

 lato, latitudine paulo breviore, lateribus parallelis antic e rotundatis, disco con- 

 cavo, insequali, linea transversa basali medio profunde exarata extrorsum 

 subtiliore, impressionibus basalibus brevibus profundis, elytris thoraee paulo 

 latioribus, elongato-ovalibus punctulatis. Long. *27. 



Tejon, one specimen. This species has very much the same proportions as 

 M. la eta, (Epipocus hetiis Lee.) 



Supplement. 



I have, for the purpose of making these pages a complete record of the addi- 

 tions to our Pacific Coleopterous Fauna, here collected notes and descriptions 

 of species derived from various sources, which have not been mentioned in my 

 Report on the Coleoptera of Pacific North America, for the P. R. R. Expl. of 

 47th Par., or in the Catalogue of Coleoptera found adjacent to the U. S. and Mex. 

 Boundary, printed in the 4th vol. of the second series of the Journal of the 

 Academy. I propose, from time to time, as fresh material is furnished by the 

 kindness of my friends, to give other supplements to the Pacific Coleoptera Fauna 

 of the UnitedStates. 



1. Dromius quadricollis, nigro-piceus, depressus, thoraee latitudine 

 breviore, quadrato, postice subangustato, transversim rugoso, postice profun- 

 dius impresso, lateribus latius marginatis pallidioribus, elytris oblongis. striatis 

 interstitiis parum convexis, subtus piceus. Long. -28. 



Puget Sound, Mr. George Davidson. Very closely allied to D. piceus, but 

 differing chiefly in the form of the thorax: the latter is broader than long, 

 scarcely narrowed behind, with the depressed margin broader, the disc more 

 rugous, the dorsal line deeper, and the posterior transverse impression deeper; 

 the posterior angles are also more regularly rounded, and the elytra are a little 

 broader. 



2. Cymindis abstrusa, picea, pubescens, capite thoraceque fortiter punc- 

 tato, fronte laevi, thoraee latitudine breviore, postice angustato, lateribus rotun- 

 datis postice subsinuatis, margine latius reflexo pallidiore, angulis posticis ob- 

 tusis, basi late rotundato, linea dorsali profunda, elytris oblongo-ovalibus nitidis, 

 striis antice punctatis, interstitiis planis, confuse subtiliter punctatis, margine 

 pallido, antennis castaneis, abdomine pedibusque piceo-testaceis. Long. -41. 



Washington Territory, Dr. Kennerly. Of the size of C. laticollis, but 

 with the elytra shining, and the thorax more broadly margined : from C. 

 reflexa it differs by its larger size, broader elytra, and less coarsely punc- 

 tured head and thorax ; the latter is also comparatively more narrowed behind, 

 with the posterior angles less obtuse.
