130. Tetraopes mancus, niger, supra coccineus, breviter nigro-pubescens, 

 thorace parce punctato, tuberculo laterali prominulo obtuse rotundato, umbone 

 dorsali modice sed subito elevato, guttis 4 nigris solitis definito, elytris mo- 

 dice punctatis, gutta humerali alteraque utrinque pone medium nigris ornatis, 

 scutello nigro, pedibus totis nigris, antennis cinereo-annulatis, articulo primo 

 ssepe rufo-tincto. Long. - 55 -61. 



Tejon, abundant. Spotted like T. 5-maculatus, but tbe middle of tbe 

 thorax is more elevated, the lateral tubercles more prominent, the elytra less 

 coarsely punctured, and the antennae annulated with cinereous hair. 



131. Saxinis saucia. Three specimens from Tejon differ from more 

 northern specimens by the thorax and elytra being more strongly punctured. 

 Such differences between forms presenting otherwise similar specific character* 

 are found in several genera of Chrysomelida?. I leave the investigation of 

 their nature for a future occasion. 



132. Exema conspersa. Abundant. 



133. Cryptocephalus a u r a t u s , (chalconatus Mann.) 



134. Pachnephorus ? smaragdulus. Abundant. 



135. Chrysochus cobaltinus. 



136. Glyptoscelis albidus, oblongus, obscure cupreus, densissime albo- 

 pubescens, thorace confertim punctato, latitudine hand breviore, lateribus late 

 rotundatis, elytris thorace latioribus confertim punctatis. Long. -30. 



Tejon: a specimen from Sacramento was given me by Mr. S. S. Rathvon. 

 Differs from G. hirtus, (Eumolpus hirtus 01. Eu. pini Say,) by the punctures 

 being smaller, by the thorax being narrower and less rounded on the sides 

 and by the hair being of a uniform whitish color. The genus Glyptoscelis 

 (J.Chevr.) is distinguished from the other genera allied to Eumolpus by the 

 mouth not being covered beneath by the prosternum, by the claws being 

 toothed, and by the tibiaj being longitudinally suleate. The head is not sculp- 

 tured as in Heteraspis. 



137. ffidionychis violascens, ovata, convexa, chalybeo-violacea, thorace 

 latitudine duplo breviorej antrorsum angustato, angulis anticis prominulis 

 posticis rectis, fortiter haud dense punctato, elytris confluenter haud subtiliter 

 punctatis. Long. -24. 



Tejon, two specimens. From its color, it appears at first sight to be a Haltica 

 of the division Graptodera. 



138. Phyllobrotica flavicollis, cyanea, thorace flavo, latitudine paulo 

 breviore, subquadrato, lateribus late rotundatis, disco postice late haud pro- 

 funde impresso, elytris punctulatis, antennis basi testaceo-maculatis. Lon^r.

Tejon. Resembles in form Galleruca atriventris Say, and belongs to 

 the same genus as that species, which has a remarkable peculiarity not before 

 noticed : in the male the third joint of the antennae is obsolete, so that the 

 organs become 10-jointed. I have not yet examined any males of the present 

 species. 



139. Phyllobrotica bivittata, flava nitida, oculis vittaque elytrorum a 

 humero fere ad apicem extensa nigris, thorace latitudine breviore, lateribus 

 rotundatis ; elytris obsolete punctulatis. Long. -18. 



Fort Tejon. A very pretty little species, without any thoracic impres- 

 sions. 



140. Diabrotica viridipennis, capite flavo, occipite nigricante, thorace 

 flavo, latitudine breviore, lateribus rectis parallelis, disco postice profunde luna- 

 tim excavato, elytris subtiliter punctulatis cyaneo-viridibus, postpectore abdo- 

 mineque nigris pube albida canis, pedibus flavis, antennis fuscis, basi flavis. 

 Long. -25.
