THOMSON (Opusc. Ent. fasc. iii. p. 324) gives additional specific characters
( 2) for his Hydaticus leevipennis, and (pp. 325 & 326) redescribes Gaurodytes
(Agabus) neglectus and subtilis (Er.) from Sweden,,
Agabus tarsatus, Zett., is recorded from Northumberland by Bold (Ent. M.
M. vi. p. 231).
Agabus sexualis, Reiche,=solieri, Auh6 : Sch. & Kies. 1. c. p. 98.
Laccophilus. Schaum & Kies. (I. c. p. 80) adopt the Panzerian names
mterruptus and obscurus, as the older hyalinus and minutus have been inextricably
bandied about between the two species.
Laccophilus biguttatus,'Khj., amerieanus,Auhe,=proximus, Say, Lee, Ann.
N. H. ser. 4, vi. p. 398; L. maeulosus, Walk., truncatus, M.a3m.,=decipiens,
Lee, Lee ibid. p. 400.
Graphoderes (Hydaticus) pieiventris, sp. n. (distinct from zonatus; Pz.) :
Thorns., Skand. Col. x. p. 351 (J =Dytiscus verrucifer, Sahib., Gyll).
Ilybius cenescens, sp. n., Thorns., Opusc. Ent. p. 125, Sweden; closely allied
to /. guttiger.
Agabus venturii, sp. n., De Bertolini, Bull. Ent. Ital. ii. p. 242, Rabbi,
Trentino; A. aubei, sp. n., Perris, L'Ab. vii. p. 6, Corsica.
GYRINIDJE.
Orectocheilus bellieri, Reiche, from Corsica, in all probability = villosus
(Miill), var.: Sch. & Kies. I. c. p. 144.
PALPICORNIA.
Tropisternus binotatus,Walk., = HydrophUus limbatus, Lee, var.: Lee,
Ann. N. H. ser. 4, vi. p. 400.
SHARP (Ent. M. M. vi. p. 253 et seq.) briefly recharacterizes Hydrobius
and its allies in Britain, viz. Helochares, Muls., Philhydrus, Sol, Enochrus,
Paracymus, and Anaceena, Thorns. He points out that three species are
confused under A. globulus (Payk.), viz. the type, a new sp., and A. bipustulata
(Steph.) ; and gives illustrations of certain of the oral organs of Hydr.
fuscipes, Hel. lividus, Phil, melanocephalus, En. bicolor, Par. ceneus, and Anglobulus.
v. KIESENWETTER (B. E, Z. xiv. Beih. p. 68) remarks upon Hydrobius
politus, Kiist., being intermediate between Hydrobius and Philhydrus. v.
HEYDEN (ib.) corrects an error in the description of the same species.
RYE (Ent. M. M. vi. p. 36) refers to the vars. subrotundus (Steph.) and
ceneus (Sol.,=chalconotus, Leach) of Hydrobius fuscipes (L.) from England.
Philhydrus maritimus, Thorns., occurs in the Canarian archipelago; P. melanocephalus,
Woll,nee. Ol,=politus, Kiist., of which 3 varieties, doubtfully
suggested as possibly entitled to specific rank, are described from the Canaries
: Sharp, Ann. N. H. ser. 4, v. pp. 14 & 15.
Laccobius. Thomson (Skand. Col. x. p. 311 et seq), who has already
created one species, L. nigriceps, at the expense of minutus (auct.), now
divides the latter into 3 species, viz. bipunctatus, minutus, and alutaceus.
Laccobius nigriceps, Thorns., occurs in Andalusia, and may be identical
with L. sinuatus, Motsch.; L. alternus, Motsch., occurs in Savoy and the
Pyrenees, and near Geneva; L. paUidus, Muls. & R., has been takeu in Andalusia
: v. Kiesenw. I. c. p. 70.
