11. A. mixta, subcylindrica (mas vix cunoiformis, femina fere obesa) obscure acnoa, birta, tborace latitudine 
uuplo breviore, lateribus antice oblique rotundalis, postice parallels, sat dense punctato, basi medio minus 1 itc fo- 
veato, punctoquc utrinque versus latcra impresso, macula laterali fulva; elytris striis punctatis, posticc ct extror- 
suni impressis, interstitiis uniscriatitn punctatis; fasoiis praccipuc anticis plus minus confluentibus, guttis parvis 
nigris saepe solis relictis, postice serratis, conjunctim rotundatis; subtus fortitcr punctata, parce pubescens. Long. 
•30— 50. 
Mas, elytris postice magis oblique attenuatis, abdominis segmento ventrail ultimo carinula subapicali transversa 
longiore. 
Feuiina, elytris postice magis rotundatim attenuatis, abdominis segmento ventrali ultimo carinula transversa brevi.

Texas, New Mexico, Kansas; Mr. Lindheimer, Capt. Pope, Mr. Xantus. The dif¬ 
ferences between this and the preceding have been already pointed out: it only remains 
to add, that the markings of the elytra vary very much: normally they consist of four 
bands and an apical dot, the first surrounds the humeral bulla; these bands then become 
confluent on the margin, enclosing a few black marginal spots, and the first and second 
coalesce on the disc, including a large irregular spot: finally all the bands become con¬ 
fluent, so that the elytra are reddish yellow, with the suture green bronzed, the humeral 
bullte, and some small dots especially behind the middle alone remaining black. 
12. A. semivittata, subcuneiformis, miuus elongata, aenco-nigra, nitida, hirta, fronte sulcata, tborace lati¬ 
tudine fere triplo breviore, antrorsum sensim angustato, lateribus oblique rotundatis flavo-marginatis, punctato, 
basi medio late triangularitcr excavato, versus latera oblique profunde impresso, elytris vitta marginali alteraque 
utrinque discoidali, lincisquc reticulatis posticis flavis, spatiis relictis violacconigris, striis punctatis posticc et cx- 
trorsum impressis, interstitiis uniseriatim punctulatis; a bumeris vix attenuatis, postice autem oblique angustatis, 
serratis apice conjunctim rotundatis; subtus punctata, densius ad latera, paulo pubescens. Long. -34—-45.

Eagle Pass, Texas, collected by Mr. A. Schott. Varies in the breadth but not in the 
general arrangement of the elytral markings. No sexual difference is obvious except that 
the females are stouter and more cylindrical than the males; the last ventral segment has 
the usual short transverse subapical crest. 
13. A. retifera, subcylindrica, nigro acnea, longius birta, tborace latitudine triplo breviore, punctato, an¬ 
tice angustato, lateribus rotundatis, medio late canaliculato, versus angulos oblique profunde impresso, elytris ma- 
culis flavis varie conncxis, vittam reticulataiu fere ad apicem extensam utrinque formantibus, guttaque apicali 
parva ornatis, striis punctatis, extrorsum et postice impressis, interstitiis uniseriatim punctulatis, postiee oblique 
rotundatis, serratis; subtus punctata, subtilius ad abdominis medium, parce pubescens. Long. -34.

Fort Tejon, California, one specimen, Mr. Xantus. The margin is yellow, interrupted 
by black spots, and more or less connected with the discoidal vitta. Last ventral seg¬ 
ment as usual.
