Crossidius Lec. 
C. suturalis, fulvus, subtilius flavo-pulbescens, capite, antennis, postpectoris 
lateribus, pedibus thoraceqne supra nigris, hoc latitudine paulo breviore, snb- 
rotundato, opaco vage grosse et subtilius punctato, subinsequali, lateribus 
obtuse angulatis, margine basali ad latera valde prominulo ; elytris antice 
fortiter postice subtilius et dense punctatis, vitta suturali communi, antice 
angusta, postice dilatata nigris, spina suturali parva armatis, scutello nigro. 
Long. -62. 
One female found in Sonora by Mr. Schott. This species has entirely the 
form ofC. testaceus, but the elevated lines of the elytra are hardly dis- 
tinct, and the punctures of the elytra anteriorly are smaller, and finally the 
suture terminates in a small spine. The black disc of the thorax does not 
reach the sides, so that a yellow margin is seen each side ; the dilated portion 
of the black sutural vitta extends backwards from the anterior third forming a 
very elongate oval black spot. 
Tragidion Serv. 
T. annulatum, nigrum velutinum, thorace lateribus postice fortiter an- 
gulatis, elytris fulvis ad basin late nigris, antennarum articulis duobus primis 
nigris, reliquis fulvis ad apicem nigris. Long. 1*1. 
One male, Sonora, Mr. Schott. Very different from T. coquus and its 
varieties by the color of the antennae : the lateral angle of the thorax is more 
prominent, and the two small horns between the antennse are longer, more 
compressed and more rounded at the tip : the third and fourth joints of the 
antennse are very densely clothed at the tip with black hair. 
Rhopalophorus Serv. 
R. rugicollis, plumbeus, pube subtili depressa cinerea pruinosus, thorace 
rufo, latitudine sesqui longiore, antrorsum paulo angustato, lateribus late ro- 
tundatis, dorso subglabro, transversim plicatim rugoso et punctato, elytris pro- 
funde punctatis ad apicem truncatis. Long. -38. 
One specimen, Texas, Mr. Haldeman. This species has the same color and 
general proportions asR. longipes (Stenocorus longipes Say), but differs by 
the form and sculpture of the thorax. 
Clythra Fabr. 
C. militaris, oblonga subelongata, nigro-virescens, capite opaco rugose 
punctato, thorace brevi opaco, ad latera transversim biimpresso, elytris sub- 
nitidis punctatis, macula magna obliqua basali alteraque rotundata subapicali 
rubris, illo puncto humerali nigro signato. Long. '17. 
One specimen, New Braunfels, Texas, Mr. Lindlieimer. Seems by the large 
and prominent anterior coxas to belong with the group Anomoia. 
Megalostomis Lac. 
M. mucorea, oblonga, convexa, nigra, undique sequaliter dense albo- 
pubescens, confertim subtilius punctata, elytris macula humerali magna rufa ; 
antennis articulo 3io parvo testaceo, 4to triangulari longiore. Long. -25 — '2S. 
Vallecitas and Fort Yuma, California. Differs from any described by La- 
cordaire by the uniform dense pubescence. It seems however to belong to his 
first division Minturnia, and to find its place near M. dimidiata. 
Babia Lac. 
B. tetraspilota, breviter ovata, postice latior, nigra nitida, subtus cin 
ereo pubescens, supra glabra, capite Isevi, thorace parce punctato, antrorsum 
sensim angustato, lateribus subrectis, transversim valde convexo, elytris 
striatim punctatis, macula magna obliqua humerali postice latiore, alteraque 
subapicali rotundata rubis. Long. '11.
