1189. Agabus gougeleti, Reiche, Ann. Soc. Fr. 1863, p. 474. Corsica. 
‘‘Ovalis, parum convexus, atro-piceus, nitidus. Caput coriaceum, ante oculos utrinque transversim 
impressum ; antennis palpisque rufo-testaceis, his apice piceis. Thorax capite fere duplo latior, 
latitudine plus dimidio brevior, antice profunde emarginatus; angulis acutiusculis; a latere paulo 
rotundatus, postice parum sinuatus; angulis rectis, acutiusculis; disco coriaceo, antice transversim 
punctato-impresso, a latere late rufo-testaceo, basi medio levigato utrinque linea transversali punctata 
instructo. Scutellum piceum, coriaceum. Elytra thoracis basi latitudine, inde ad medium parum 
dilatata, ultra medium attenuata, apice conjunctim rotundato-acuminato, triseriatim punctata ; punctis 
piligeris ; fusca ; basi et ad latera vage testaceo-maculata, paulo infra medium macula albida translucida 
laterali indeterminata et inde ad apicem maculis similibus minoribus nonnullis sparsis. Subtus niger, 
pedibus rufescentibus, femoribus basi nigris. Mas et fem. Long. 84, lat. 43 m.m.” 
Icannot 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. 8. 
1190. Agabus heffneri, Aubé, Ic. V. p. 170, pl. 21, f. 2.—Spee. p. 345. Suecia. 
““Oblongo-ovalis, brevior, nitidus, subtilissime reticulato-punctatus, niger; antennis ferrugineis ; 
pedibus ferrugineo-piceis ; elytris paulo ultra medium vix ampliatis, tribus seriebus punctorum minorum 
notatis. Long 74, larg. 33 m.m.” 
[A description follows the above diagnosis]. 
““G. Wasastjerne simillimus, 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 : 
“ Klongatus, oblongo-ovalis, parum depressus, nitidus, impunctatus, supra brunneus, infra rufo-ferru- 
gineus ; capite toto late ferrugineo ; therace late ad latera (interdum fere toto) pedibusque ferrugineis ; 
elytris ad basin anguste et macula oblonga apicali ferrugineis. Long. 22 lin., lat. 1} lin.” 
Further the insect is stated to have a visible scutellum, the anterior tarsi 4~jointed, the middle ones 
5-jointed. It would thus appear probable that the insect cannot be placed in any genus known to 
me.—D. 8. 
1192. Agabus interruptus, Perroud, Ann. Soc. Linn. Lyon. 1864, p. 79. New Caledonia. 
“Klongato-ovatus, minus convexus. Capite nigro in vertice macula ferruginea. Prothorace nigro, 
rufo-marginato. lytris flavis, nigro-striatis, striis interruptis; subtus piceo-niger; ore, antennis pedi- 
busque ferrugineis. Long. 0 m., 009, larg. 0 m., 003.” 
“ Pris a Kanala par M. Montrouzier.” 
“Cette espéce doit se placer pres de ’Agabus oblongus ; mais elle est plus petite, plus attenué 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. Mose. 1853, III, p. 159. Russian North America. 
“ Ovatus, minus convexus, posterius rotundatus, nigro-piceus, supra nonnihil aeneo-micans, nitidissimus, 
subtilissime punctulatus; ore antennis, elytrorumque margine late, rufo-ferrugineis ; thorace impres-
