GKO. H. HORN, M. T). 
A. abstoi’KiiH n. sp. — Moderately elongate, siibcylindrieal, narrower bebind, 
dark brassy bronze, moderately shining. Antennse piceotis, faintly bronzed, 
iittaining the middle of the thorax, serrate from the fifth joint; head convex, 
without trace of impression, sparsely indistinctly punctate. Thorax a little 
wider than long, slightly narrowed at base, sides feebly arcuate, sliglitly sinuate 
in front of the hind angles, which are rectangular and without carina, margin 
nearly straight, feebly deflexed in front; disc convex, without impressions, eitlier 
median or lateral, surface distantly obliquely strigose, with a reticulate aj>pear- 
auce; scutellum not carinate; elytra scarcely sinuate at the sides, the apices 
rounded and serrulate; disc convex, without trace of costae, basal dei)ression 
feeble, surface imbricate, a little more roughly near the apex; body beneath as 
above; prosternal lobe truncate and broadly emarginate, the intercoxal process 
pai-allel and obtuse at ti}), jiropleurae widely reticulate; metasternum at sides 
with distant strigse. Abdomen sparsely punctate, with a somewhat widely re- 
ticulate appearance ; pygidium sparsely punctate, not distinctly carinate; chiws 
broadly toothed. Length .12 — .15 inch.; 3 — 3.75 mm. 
4/u/e.— Prosternum moderately tdosely punctate, sparsely pube.s- 
eeut ; tirst ventral segment with a short, smooth, median groove at 
its posterior edge. 
Female . — Prosternum sparsely jtunctate ; ventral segments simple. 
Variations . — None have been observed in the many specimens 
seen . 
This species, like ventralis of the preceding series, resembles 
Taphroceras a.griloides, and in the present rather more so than in that 
from the fact that there is here no pubescent elytral vitta. 
When the thorax is viewed fi'om above and from behind, the 
scul|)ture has a reticulate appearance, but when seen from in front 
is very obliquely and not closely strigo.se. 
Hab . — Southern Arizona. Collected rather abundantly by i\[or- 
rison, and by him widely distributed in collections. 
A. Ijeooiitei Sauuders. — Form rather more robust than fallax. dull olivace- 
ous bronze, sometimes slightly brassy, elytra with ])ubesceut spaces. Anteuuse 
sliglitly passing the middle of the thorax, piceous with slight feneous lustre, 
serrate from the fifth joint; head slightly convex, or very feebly impressed me- 
dian line, and a slight transverse depression below the middle of the front in 
some specimens, surface coarsely punctate, occiput slightly strigose; clypeus 
broad at base. Thorax a little wider than long, sides feebly arcuate, margin 
sinuate, hind angles rectangular, with a well defined straight carina; disc mod- 
erately convex, with a deep median impression composed of two fovea united by 
a groove, lateral obli(pie depression moderately deep, surface coarsely punctate, 
sometimes .slightly transversely strigose; scutellum transversely carinate; elytra 
feebly sinuate behind the humeri, slightly broadened behind the middle, apices 
almost conjointly rounded, serrulate; disc slightly depressed at middle with a 
very vague costa each side, surface subgrauulate, with pubeshent spaces as fol- 
lows; at basal depressions an indistinct broad band iii front of middle, oblique
