Thomson (Opusc. Ent. fasc. iii. p. 324) gives additional specific characters 
( $ ) for his Ilydaticus loimpcnnis, and (pp. 326 & 320) redescribes Gauro- 
dytes {Agahus) neglectus and suhtilis (Er.) from Sweden. 
Agabus tarsatus, Zett., is recorded from Northumberland by Bold (Ent. M. 
M. vi. p. 231). 
Agahus sexualis, Reiche, = solieri, Aube : Sch. & Kies. I, c. p. 98. 
Laccophilus. Schaum & Kies. (/. c. p. 80) adopt the Panzerian names 
interruptus and ohscurus, as the older hyalinus and minutus have been inex- 
tricably bandied about between the two species. 
Laccophilus higuttatus^ Kby., ame; Aubd, Say, Lee., Ann. 
N. II. ser. 4, vi. p. 398 j L. maculosuSy Walk., truncatus, Maj\n.,=decipiens, 
Lee., Lee. ibid. p. 400. 
Graphoderes {Ilydaticus') piciventris, sp. n. (distinct from zonatus, Pz.) : 
Thoms., Skand. Col. x. p. 351 (5 —Dytiscus verrucifer, Sahib., Gyll.). 
llybius miescens, sp. ii., Thoms., Opusc. Ent. p. 125, Sweden ; closely allied 
to I. 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. 
Gyrinid^e. 
Orectocheilus bellieri^ Reiche, from Corsica, in all probability = villosus 
(Miill.), var. : Sch. & Kies. 1. c. p. 144. 
Palpicornia. 
Tropisternus binotatus, Walk., = Hydrophilus linibatus, hec., var.: Lee., 
Ann. N. II. ser. 4, vi. p. 400. 
Sharp (Ent. M. M. vi. p. 253 ct seq.) briefly recharacterizes Hydrobius 
and its allies in Britain, viz. Ifelocharcs, IMuls., PhUhydrus, Sol., JEnoclirus, 
Paracymus, and Anaccena, Thoms. He points out that three species are 
confused under A. globulus (Payk.), viz. the type, a new sp., and A. bipustu- 
lata (Steph.) ; and gives illustrations of certain of the oral organs of Hydr, 
fuscipes, Hel. lividus, Phil, melanocephalus, JEn. bicolor, Par. ceneus, and An- 
globulus. 
V. Kiesenwetter (B. E. Z. xiv. Beih. p. G8) remarks upon Hydrobius 
politus, Kiist., being intermediate between Hydrobius and PhUhydrus. 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 
eetwus {Sol., = chalconotus, Leach) of Hydrobius fuscipes (L.) from England. 
PhUhydrus maritimus, Thoms., occurs in the Canarian archipelago ; P. me- 
lanocephalus, Woll., 01.,— politus, Kiist., of which 3 varieties, doubtfully 
suggested as possibly entitled to specific rank, are described from the Cana- 
ries : 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, Tlioms., occurs in Andalusia, and may be identical 
with L. sinuatus, Motsch. ; L. alternus, Motsch., occurs in Savoy and the 
Pyrenees, and near Geneva ; L. pallidus, Muls. & R., has been taken in An- 
dalusia : V. Kiesenw. 1 . c. p. 70.
