" Ovalis, parum convexus, atro-piceus, nitidus. Caput ooriaceum, ante oculos utrinque transversiin 

 impressum ; antennis palpisque rufo-testaceis, his apice piceis. Thorax caj)ite fere duplo latior, 

 latitudine plus dimidio brevier, antice profunde emarginatus ; angulis acutiusculis ; a latere paulo 

 rotundatus, postice parum sLnuatus ; auguUs rectis, acutiusculis ; disco coriaceo, antice transversim 

 punctato-impresso, a latere late rufo-testaceo, basi medio loevigato utrinque linea transversal! punctata 

 instructo. Scutellum piceum, coriaceum. Elytra thoracis basi latitudine, iude ad medium parum 

 dilatata, ultra medium attenuata, apice conjunctim rotundato-acuminato, triseriatim punctata ; punctis 

 piligeris ; fusca ; basi et ad latera vage testaceo-maculata, paido infra medium macula albida translucida 

 laterali indeterminata et inde ad apicem maculis similibus minoribus nonnullis sparsis. Subtus niger, 

 pedibus rufescentibus, feuioribus basi nigris. Mas etfem. Long. 8 J, lat. 4^ m.m." 



I cannot from the description identify this species with any certainty; the specimens I have seen in 

 collections under the name are a variety of Dytiscus conspersus (No. 714). — D. S. 



1190. Agabus h<EflFneri, Aube, Ec. V. p. 170, pi. 21, f. 2.— Spec. p. 345. Suecia. 



" Oblongo-ovalis, brevior, nitidus, subtilissime reticulato-punctatus, niger ; antennis ferrugineis ; 

 pedibus ferrugineo-piceis ; elytris paulo ultra medium vix ampUatis, tribus seriebus punctorum minorum 

 notatis. Long 7|, larg. 3| m.m." 



\^A description follows the above diac/nosis^. 



" G. Wasastjernae similUmus, sed paulo major, prothoracis angulis posticis magis obtusis, elytris 

 punctura minus distincta, subtiliter reticulatis ; mas, tarsis anterioribus magis dilatatis et elongatis 

 distinctus." — Thoms. op. Ent. VI., p. 539. 



1191. Agabus hydroporoides, Murray, Ann. Nat. Hist. 1859, p. 120. Old Calabar. 



In the reprint, Col. Old Calabar, p. 75, this is assigned to the genus Celina, and diagnosed as 

 follows : 



" Elongatus, oblongo-ovalis, parum depressus, nitidus, impunctatus, supra brunneus, infra rufo-ferru- 

 gineus ; capite toto late ferrugineo ; thorace late ad latera (interdum fere toto) pedibusque ferrugineis ; 

 elytris ad basin angiiste et macula oblonga apicali ferrugineis. Long. 2\ lin., lat. 1^ lin." 



Further the insect is stated to have a visible scutellum, the anterior tarsi 4-jointed, the middle ones 

 6-jointed. It woiild thus appear probable that the insect cannot be placed in any genus known to 

 me. — D. S. 



1192. Agabus interruptus. Perroud, Ann. Soc. Linn. Lyon. 1864, p. 79. New Caledonia. 



" Elongato-ovatus, minus convexus. Capite nigro in vertice macula ferruginea. Prothorace nigro, 

 rufo-marginato. Elytris flavis, nigro-striatis, striis interruptis ; subtus piceo-niger ; ore, antennis pedi- 

 busque ferrugineis. Long. m., 009, larg. m., 003." 



" Pris a Kanala par M. Montrouzier." 



" Cette espfece doit se placer pres de 1' Agabus oblongus ; mais eUe est plus petite, plus attenuS en avant, 

 un peu moins convex, et la dilatation des trois premiers articles des tarses soit anterieurs, soit interme- 

 diaires chez les males est moins forte." 



This is probably a Copelatus allied to No. 847, possibly identical therewith. — D. S. 



1193. Agabus irregularis, Mann. Bull. Mosc. 1853, III, p. 159. Russian North America. 



" Ovatus, minus convexus, posterius rotundatus, nigro-piceus, supra nonnUiil aeneo-micans, nitidissimus, 

 subtilissime punctulatus ; ore antennis, elytrorumque margine late, rufo-ferrugineis ; thorace impres-
