1204. Agabus terminalis, Melsh., Proc. Acad. Phil. II, p. 27. North America. 
“ Black, opaque, densely and very finely striate ; labrum, palpi and antenne testaceous. Nearly 5 1. 
long, 22 1. wide. Inhabits Pennsylvania.” 
This is not mentioned by Crotch in his “‘ Revision of the North American Dytiscide.”—D. 8, 
1205. Agabus truncatipennis, Sol., Gay, hist. Chil. IV, p. 278, pl. 5, £1. Chili. 
“A, oblongus, ellipticus ; capite nigro ; prothorace ochraceo, medio macula transversa, trapeziformi, 
fusca ; elytris apice oblique truncatis, subacuminatis, ochraceis, nigro irregulariter reticulatis maculisque 
quatuor oblongis, nigris, lateribus utrinque notatis, ore antennisque luteis ; pedibus obscuris. Long. 
sub 4 lin. 4, latit. 2 lin.” 
“‘ Esta especie se parece mucho al Colymbetes nigriceps, pero es menos angosta y differe ademas por 
los caracteres genericos. La encontramos en Santiago y en los bajas cordilleras de Coquimbo.” 
The figure indicates, a species of Lancetes, and I expect it will prove to be C. nigriceps, or C. pre- 
morsus.—D. 8. 
1206. Agabus venturii, Bert., Bull. Ent. It. II, p. 242. Italy. 
“ Ovatus, subtiliter reticulato-strigosus, niger, elytris margine extremo fuscis, opacis, antennis 
pedibusque ferrugineis. Long. 7 mill., lat. 4 mill.” 
“ Assai somigliante nella forma all’ Agabus arcticus, Payk., &., . pyran 
1207. Anisomera bistriata, Brullé, Hist. Nat. V, p. 205, pl. 8, f. 3, Aubé, Spec. p. 396. Chili. 
“‘ Oblongo-elongata, depressa, supra flavicans, infra rufescens ; thorace postice angustiore; elytris 
elongatis, ad apicem dilatatis, creberrime nigro-irroratis. Long. 64, larg. 3m.m.” Aubé, Lc. 
[This is followed by a description. | 
This insect is, I believe, still only known by the above described mutilated female individual ; its 
genus is quite doubtful to me.—D. 8. 
1208. Anisomera recta, Lec., Ann. Mag. Nat. Hist., 4th ser. IV, p. 375. North America. 
‘ Hlongato-ovalis, eneo-nigra, subtiliter dense reticulata ; prothorace longitudine plus triplo latiore, 
postice subangustato, lateribus antice late rotundatis, versus basin paulo obliquis vix subsinuatis, angulis 
posticis rectis, basi truncato ; elytris thorace vix latioribus, utrinque seriebus tribus punctorum solitis, 
externa minus distincta. Long. 10 m.m.” 
According to an individual recently transmitted to me by the describer, this species differs from No. 
662, by the more evidently reticulate surface, and the less degree of sinuation of the sides of the 
prothorax. It should be placed in the genus Agabus after A. cordatus (No. 662)—D. S. 
1209. Celina grossula, Lec., New spec. Col. I, 1863, p. 22. North America. 
“ Piceo-rufa, nitida, elytris obscuris haud dense punctatis, punctisque majoribus triseriatim digestis, 
serie interna evidentiore, apice conjunctim breviter acuminatis. Long. :22. Louisiana.” 
‘This species is very much larger than C. angustata, but agrees with it i form, colour and sculpture ; 
the upper surface is, however, a little more convex, and the sides of the thorax slightly less rounded.” 
A specimen of this species recently transmitted to me by its describer seems extremely close to C. 
aculeata but is a little larger and paler in colour.—D. S.
