of the anterior tibia? is prolonged. A variety occurs, in which the third costa 

 is entirely wanting, and the first and second have the same origin at the 

 base. 



78. Nosoderma diabolicum. 



79. Nosoderma pustulosum, sordidum, thorace obovato, latitndine 

 longiore, angulis anticis rotundatis, posticis obtusis, dorso medio deplanato, 

 lateribus late foveatis,tuberculis pai-vis subnitidis parcis, prsecipue ad marginem 

 et in medio positis, elytris intra humeros subexcavatis, medio deplanatis, ante 

 apicem subretusis, tuberculis confertis subnitidis undique obsitis. Long. -92. 



One specimen, Tejon. Of the size and form of N. diabolicum, but the 

 tubercles are smaller, and less irregular, the base of the elytra is not exca- 

 vated near the scutellum, and there are no velvety spots on the thorax and 

 elytra. 



80. Nosoderma plica turn, elongatum, nigro-sordidum, thorace obovato, 

 latitudine longiore, angulis anticis rotundatis, posticis obtusis, subinaequali, 

 medio granulis parcis nitidis, ad latera tuberculis parvis signato, elytris paral- 

 lelis ante apicem triverrucosis, prsecipue ad latera et apicem tuberculatis, 

 costula humerali alteraque pone medium obliquis munitis. Long. -61. 



Tejon, three specimens : very different from any other seen by me. The 

 basal costa commences at the humerus, runs slightly inwards, and terminates 

 at the middle : another oblique fold commences near the margin a little before 

 the middle, runs parallel with the first, and ends about the third fifth ; the 

 inner anterior tuberosity is also a little prolonged in the same direction. There 

 is a slight vestige of a costa at the base, parallel with the suture and about 

 midway between it and the humeral costa. The antennal cavities are not so 

 abrupt as in N. d i a b o 1 i c u m. 



81. Eleodes dentipes. 82. E. latico His. 83. E. quadricollis. 

 84. E. consobrina. 85. E. Veseyi. 86. E. scabrosa. 



87. Eleodes scabripennis, atra, ovata, subnitida, thorace latitudine 

 paulo breviore, subquadrato, lateribus rotundatis, postice sensim paulo angus- 

 tato, angulis posticis obtusis, dense punctato, ad latera subasperato, elytris 

 ovalibus, thorace latioribus, dorso parum convexis, postice valde declivibus, 

 granulis parvis inordinatis dense exasperatis, et versus suturam punctatis, 

 tibiis muticis, prosterno postice oblique submucronato, antennis extrorsum 

 parum incrassatis. Long. -65. 



One specimen, Tejon. Of the same size and sculpture as E. Veseyi, but 

 differing by the thorax being much less rounded on the sides, by the posterior 

 angles not being at all prominent, and by the prosternum being a little more 

 prominent behind. 



88. Amphidora osculans. 89. A. littoralis. 



90. Helops rugulosus. 



91. Helops angustus, elongatus, ameo-niger, subnitidus, ^thorace latitu- 

 dine baud breviore, vix convexo, lateribus rotundatis, angulis posticis sub- 

 rectis, capite dense aciculato-punctato, elytris thorace paulo latioribus, striis 

 profundis antice subpunctatis, interstitiis parce subtiliter punctulatis, antennis 

 pedibusque rufo-piceis, palpis tarsisque piceo-rufis. Long. -31 --36. 



Tejon, two specimens. Quite distinct from all others known to me by the 

 above characters. 



92. Coniontis viatica. 



93. Coniontis abdominalis, ovalis, subcylindrica, convexa, nigra, sub- 

 nitida, thorace lateribus minus subtiliter marginatis, medio parce, lateribus 

 densius subtiliter punctato, elytris rugosis, sat dense punctatis, abdomine 

 confertim rugose punctato. Long. -66.
