Hydroscaphidj^. 
J. L. Leconte, Tr. Am. Ent. Soc. v. pp. 45 & 46, proposes the above 
family for the reception of a new genus, Ilydroscapha, differing from 
Limnobius, and all other Hydrophilidce, in its laminate and widely sepa- 
rated hind coxse and peculiar abdomen, and connecting the Hydrophilidce, 
ScaphidiidcB, and (?) Trichopterygidoe. Type, H. natans, sp. n., id. 1. c. 
p. 46, Los Angeles, California. 
D. Sharp, Ent. M. M. xi. pp. 101-104, reprints this paper, confirming 
Leconte’s characters, except that the antennae are 8-jointed, and the tarsi 
only 3- jointed, and that the affinity to the Trichopterygidce is stronger 
than Leconte imagined. The genus occurs in Europe, a new species, H. 
crotchi, from Madrid, being described (p. 103), and the suggestion is made 
that Limnobius evanescens. Kies., and L. gyrinoides, Aubd, are possibly 
members of it. 
Paussid.®. 
Faussus procerus. The vapour given off by this species does not hurt 
the skin, but the yellow crust left after the first explosion produces on 
the tongue the effect of a burn. Raff ray. Pet. Nouv. vi. p. 376. 
Faussus cornutus recorded from the Sahara; L. Fairmaire, tom. cit. 
p. 407.
