One specimen, San Diego. Has very much the form of A. vicinus. The head 
is tolerably strongly punctured, with a narrow smooth frontal line. The 
antenne are less slender than in the other species of this group, and the eyes, 
though not small, are less prominent. 
23. A. cervinus, testaceus, elongatus, subtilius pubescens, capite fusco, 
postice subtruncato, punctato, medio levi; thorace longiusculo ovato, punctulato, 
elytris densius punctatis, pone medium nigricantibus, gutta utrinque postica 
apiceque flavis. Long.-1.

Found everyplace, from Lake Superior to Georgia, and from New York to 
Nebraska. A.very variable species; ‘the most common form is that above 
described ; there are others fuscous, legs and antenne testaceous, elytra black, 
with a basal spot, and one behind-the middle testaceous ; others, again, are 
entirely yellow-testaceous. 
Some of these varieties come very near to A. Haldemani, but are immediately 
distinguished by the occiput not being channeled. 
24. A. punctulatus, elongatus, niger nitidus, cinereo-pubescens, capite 
postice subtruncato, thoraceque confertim subtilius punctatis, hoe longiusculo, 
postice subangustato, elytris minus convexis, dense punctatis. Long. +1.

San Jose and San Diego. The frontal line is narrow and slightly elevated. 
The eyes are smaller than in the preceding, but are moderately prominent. 
25. A. Haldemani, ater,subnitidus, breviter pubescens, confertim punctatus, 
capite postice truncato, occipite impresso, thorace longiusculo ovato, elytris - 
maculis utrinque duabus. magnis flavis, antennis pedibusque testaceis.

A. quadriguttatus||Hald. Pr. Ac. 2, 304. 
Massachusetts and Pennsylvania. Varies with the anterior spot diffuse so as 
to cover nearly the anterior half of the elytra, and the posterior spots coalescing: 
so that the elytra become yellow, with the suture, a transverse band at the mid- 
dle, and the apex fuscous. The thighs are sometimes fuscous. ‘The frontal line 
is narrow and indistinct, and the points on the head are not very dense. Those 
of the elytra are a little larger and very dense. The thorax becomes very 
slightly cylindrical at base. It seems to resemble very much A. 4-maculatus 
(Ferte 203) from Europe, but the pubescence is distinct, and equally distributed 
over every part of the body. 
26. A. quadrilunatus, ater subnitidus, breviter pubescens, content

elytris maculis utrinque duabus, tibiis, tarsis, antennarumque basi ferrugineis.

One specimen, New Mexico, Fendler. Very close to A. Haldemani; the 
head is a little more square behind, and there is scarcely a trace of an occipital 
impression. ‘The thorax is more convex in front, though scarcely enough so to 
be deseribed as round, and I have therefore doubts about it being identical with 
the California species ‘described by Ferte.
