tliorace traiisverso, aiigulis auticis depressis, sulireetis, posticis acutiusculis, 

 disco convexo, basi sinuato in medio depresso ; scutello nioro. Elytiis luteis 

 obsolete piinctato-striatis, stiiis extroi-suni ct ad a])icem olditeratis ; puuctis

Apparently allied to A. ^jerplexus, Baly, but apart from tlie colour (ujkiu 

 wliicli in this variable genus mueli stress cannot be laid) tlie elyti'a are Udt 

 angularly produced, their ajjex imly 1 icing slightly emarginate ; nnr are they 

 distinctly striate, but have rows of close, small brown ])unctures, inters])erse(l 

 with irregular ones at the sides. 



Ar(:'Acii>{ is one of the most l>eautiful and interesting genera, of the Hisjiidir, 

 c()nd)ining strangeness of form with beauty of colour. Six s])ecies are 

 described, all from Soutli Aiiierii'a.

Huh. Nanegal (3-4000 feet). Two sitecimens. 



These appear to me to agiee fairly with the description given by Kii'scli 

 of his species from Chanchamayo. Tlie veiy large size of one of these (19 

 millimetres in length), the coloui' of the antenna', of the underside, and 

 elytra, seem to point to the conclusion that our species is identical. A sec(md 

 obviously conspecitic measures 15 millimetres. In neither is the suture black 

 at the apex beneath, and some ininor disere]iancies such as may be due t<j 

 variation are ol)serval)le.

Hah. Banks of the Guayas, Guayacpiil. Two specimens. 



The species of this genus are difficult to identify. The specimens, both 

 from Guayaquil, proliably belong to different species, but are closely allied in 

 form and sculpture, and pertain to tlie section of the genus with the elyti'a 

 not gil)])ous. In one, the elytra have numerous small black sj^ots, and the 

 body is black lieneath ; while in the other, the elytra are ferruginous, with 

 only one or two spots near their base, and the body is of the same ferruginous 

 colour, as well as the legs.

Hah. Banks of the Guayas, Guaya(|uil. 



Three specimens of a Coptninjrjit of the size of, and in its gil)bous-con\e\ 

 form allied to, V.judaica., but differing in colour, having the disk of the elytia 

 and of the prothorax deeji pitchy lirown. These specimens I cannot identify
