7. A. comata, cuneiformis, valde elongata, nigra subzenea, pilis longis lanugixosis albis parce vestita, fronte 
late concava, capite thoraceque grosse punctatis, hoc latitudine sesqui breviore, lateribus parallelis antice paulo ro- 
tundatis, apice late marginato, medio longitudinaliter haud profunde excavato, ad basin utrinque breviter oblique 
excayato, elytris a basi sensim, postice autem magis attenuatis et serratis, crenato-striatis, interstitiis alternis ele- 
vatis, punctis paucis parvis flavis ornatis; subtus preecipue ad latera longe albo-pubescens. Long. -38. Tab. XII.,

One specimen found on the Colorado river, below the Gila. The punctures of the 
under surface are less deep at the middle of the anterior segments of the abdomen; the 
last ventral segment has no subapical carina, but the groove is distinct. The two outer 
strie of the elytra are confluent behind the humerus.

8. A. gibbula, nigro-zenea, supra parce albo-pilosa, capite subtilius, thorace sat dense punctato, hoe latitu- 
dine baseos duplo breviore, lateribus obliquis parum rotundatis, antrorsum valde angusta, medio triangulariter ex- 
cavato, basi utrinque profunde foveato; elytris humeris valde callosis, angulo producto, thoracis basin amplectente, 
punctis quadratis seriatis, striis externis et ad apicem profundis, 1ma antice fere obliterata, interstitiis uniseriatim 
punctulatis, nigro-cyaneis, maculis pluribus magnis flavis ornatis, posticis rufotinctis; subtus longe dense albo-pu- 
bescens, vitta media subglabra. Long. -5. Tab. XIL, fig. 6.

Two specimens found by Dr. T. H. Webb on a journey from El Paso to San Diego. 
The front is very slightly impressed: the sides of the elytra, from the prolongation of the 
humeral angles, are deeply sinuate near the base; their outline in the male is somewhat 
cuneiform, narrowing in aslight curve from the base, they are strongly serrate behind, and 
the tip is conjointly rounded: in the female they are nearly parallel, and slightly sinuate for 
three-fourths the length, then obliquely narrowed to the apex. The spots of the disc are 
seven or eight in number, forming a series on the 3d, 4th and 5th intervals, and are un- 
equal in size: the other spots are, a humeral dot, three marginal spots occupying two in- 
tervals, and finally three spots alternate with the marginal ones, on the 3d interval from 
the side; these last are tinged with scarlet: the two outer striz are confluent anteriorly. 
The punctures of the under surface are more sparse, but not smaller at the middle than at 
the sides: the last ventral segment has a very broad carina and the usual groove.

9. A. pulchella, supra violaceo-znea, nitida, hirta, thorace latitudine plus duplo breviore, lateribus late 
rotundatis, ante basin haud latiore, sat dense punctato, ad basin trifoveato, fovea media majore haud profunda, 
macula parva flava utrinque ad angulum szpe ornato; elytris striis punctatis postice et extrorsum impressis, inter- 
stitiis uniseriatim punctatis, macula magna laterali postice latiore, fasciis duabus posticis flavis, (guttisque pluri- 
bus posticis seepe ornatis,) postice valde serratis, apice conjunctim rotundatis; subtus nigro-zenea, parce punctata, 
parum pubescens, Tong. -28—-40,
