from New Zealand—viz., Drepanacra and Micromus—the former being 
purely Australasian, the latter world-wide. New Zealand possesses but 
one species of each of these genera, and both these species are also common 
in Australia. A new species of Micromus is added in this paper, together 
with a new species of the genus Boriomyia. 
Family BEROTHIDAE. 
In this family the forewing has the radial sector normal; the hindwing 
has the basal cross-vein connecting Rs with M placed in the normal trans- 
verse position, and Cu, runs for a very long distance close to and parallel 
with the posterior margin of the wing, sending to it numerous branched 
veinlets. This condition of Cu, is absolutely diagnostic for the family. 
Genus PROTOBIELLA n. g. 
die fused distally with R, in both Vini Forewing with the costal 
ace very narrow at the base, but increasing to a consideratie width in 
cross-vein between R and M, just above the usual one connecting M with 
Cu, ; M and Cu both dichotomically branched ; no definite gradate series, 
but three cross-veins forming a partial outer such series connect М; +2 
апа the two most posterior branches of Rs respectively ; other cross-veins 
are—one between the two main branches of two between Мз; an 
Cu,, one between the two main branches of Cu, and the usual basal cross- 
veins between Cu,, 1A, and 2A respectively, the latter one obliquely placed. 
Hindwing with the costal space very narrow all the way, and carrying 
only unbranched veinlets; Rs with five branches, and connected with R 
by only two cross-veins; Cu, runs close above and subparallel to the . 
posterior margin to well beyond half-way ; the part of Cu, lying beyond 
the distal end of 1A does not send a series of veinlets arranged pectinately. 
to the margin, such as descend from 14A itself, but gives off instead only 
io veinlets, which rebranch close to the margin; 1A is forked, each fork 
ending a pectinate series to the hind margin, the distal branch being much 
longer than the basal; an oblique cross-vein connects 1A with Cu,, Cu, 
being entirely absent; a portion of a distal or outer gradate series is 
represented by three cross-veins connecting Cu,, Мз 4 4, M42, and the most 
posterior branch of Rs respectively. No scales резе on hindwing in

—New Zealand only. 
T genit: resembles the Australian Spermophorella i in its rounded wings, 
shape of costal space in both wings, fusion of Sc with R, distally in both 
gs, number s cross-veins connecting Rs with R,, form of M and Cu 
ien pea which descend from Cu, distally i in the hindming in 
that and other known genera of Berothidae. In this latter character 
Protobiella is ees A the most archaic genus of the family. 
S Spermophorella is peculiar in that the females possess a more or less 
я ove area of the hindwing bearing thickened, seed-like scales attached
