active than those that frequent deeper water. A comparison of the struc- 
ture of the larv 0 B and pupae of Brazilian species is rnade with that given 
by Brauer for H. ceylanica. Tr. E. Soc. 1879, pp. 132 & 133 ; P. E. Soc. 
1879, pp. vi. & vii. ; Zool. Anz. ii. pp. 180 & 181. 
In a note on Swainson’s genus ThelidomuSy B. R. Dyer refers to Heli- 
copsyche as having been discovered in Tasmania, thinking the genus had 
only hitherto been known from India and Brazil; P. R. Soc. Tasm. 1878 
(1879), p. 17. 
Leptoceridev . 
Fritz Muller, Tr. E. Soc. 1879, has notes on South Brazilian species 
as observed by him {cf. also P. E. Soc. 1879, Zool. Anz. ii., and Kosmos, 
ii., as cited at p. 203). 
Of McLachlan’s Section ii., two genera are known to him. One (p. 133, 
not named) is near Odo7itocerum, but has the antenum not dentate, and 
the eyes of the ^ very large and contiguous ; the case, a cylindrical, 
slightly -curved sand-tube; two species known [the Recorder is of opinion 
that Mystacides alhicomis, Burm., will fall into this genus]. For the 
other, the name Grumicha (St. Hilaire; practically a new genus) is 
reserved, p. 134 ; the insect is noticed as having 2.2.2 spurs, a closed 
discoidal cell, the radius and first apical section connected by a transverse 
nervule, apical forks Nos. 1, 2, 3, and 6 in the anterior, and 1, 2, and 6 in 
the posterior wings. The cases are the well-known black Dentalinm-\ike 
tubes [the Recorder thinks this genus probably belongs to the Serico- 
stomatidee]. 
Of Section iii., there is a species of Teh'acentroriy which uses hollow 
sticks for its case (sometimes also appropriating the case of Grumicha), 
and the imago of which is remarkable for the existence of branchiae. 
Also several species placed provisionally in Setodes (for one of these the 
generic name Nectopsyche is proposed in Zool. Anz. ii. p. 40) ; and a new 
genus termed Grumichella (p. 135 ; given previously as Grumichinha in 
Zool. Anz. ii. p. 40), near Leptocerus, the case much resembling that of 
Grumicha. 
Of Section iv. (pp. 137 & 138), Muller is acquainted with three species 
(genera not named), forming their cases of leaves ; one of them inhabits 
the water that collects at the base of the leaves of Bromelice. 
Hy dropsy cliidce.. 
Fritz Muller, Tr, E. Soc. 1879, notices the habits, &c., of S. Brazilian 
species as follows : — 
Macronema (p. 139). The larvae of one species is extremely common, 
and is found under large stones. The case is a rudely-constructed accu- 
mulation of small stones ; that of the pupa more solid. 
Tinodes ? (ibid.). Cases similar to those described for this genus are 
very common. 
An unnamed genus (J,hid.), with cases similar to those of Peltopsyche 
(vide Ilydroptilidce). 
Rhyacophylax, g. n. (p. 140). Nearly allied to Smicridea, but 1.4.4 
.'ipurs in the $ and 1.4.2 in the ^ , with very extraordinary cases.
