Lee. An. Lye. 5, 155. 



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 

 antennae 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 laevi; thorace longiusculo ovato, punctulato, 

 elytris densius punctatis, pone medium nigricantibus, gutta utrinque postica 

 apiceque flavis. Long. !.

A. hizonatus Ferte, Anthic. 274. 



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 antennae 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.

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. H a Id e m a n i, ater,subnitidus, breviter pubescens, confertim punctatus, 

 capite postice truncato, occipite impresso, thorace longiusculo ovato, elytris 

 maculis utrinque duabus magnis flavis, antennis pedibusque testaceis.

A. quadngnttatus\^z\di. 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, confertim 

 punctatus, capite postice truncato, occipite vix impresso, thorace ovato, convexo, 

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

? Ferte, Anthic. 201. 



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 described as round, and T have therefore doubts about it being identical with 

 the California species described by Ferte.
