Brotocy.—The larvae were found sparsely in a slowly flowing pool 
of a small mountain stream. The adults were taken mostly in the 
daytime when they were easily beaten from the vegetation surrounding 
the stream. 
Genus Atanatolica Mosely 
Atanatolica, Mosely, 1936, p. 85. [Type-species: Mystacides brasilianus Brauer, 
1865, by original designation.] 
I place the Dominican species in this genus primarily because of 
the close similarity of the male genitalia to the type-species. There 
are a few differences in the venation in the two species: in A. domini- 
cana, fork 1 in the forewing is petiolate, and there is no crossvein in 
the hindwing between R»2,3 and R4,;. 
The larvae and pupae of the genus are described herein for the 
first time. They are especially unusual because they spend most of 
their time out of water crawling and pupating on moist rocks. 
Atanatolica dominicana, new species 
Fiavures 193-195, 209-221 
On the basis of male genitalia, this species is closely related to 
A. brasiliana (Brauer), from which it differs in the apicolateral angles 
of the tenth tergum, which are finger-like rather than truncate; 
the apex of the aedeagus, which is bilobate; and the apicomesal 
angle of the basal part of the clasper, which is obliquely truncate. 
There are also differences in the venation as stated above. 
Avutt.—Length of forewing: male 7-9 mm, female 5-6 mm. Head, 
basal antennal segment with a cream-colored middorsal line, remainder 
of antennae black with white annulae, forewing brown (darker in 
female) with apex, apical fringe, and posterior margin cream colored. 
Male genitalia: ninth segment annular; cercus elongate, narrowing 
apically; tenth tergum with paired apicodorsal finger-like appendages, 
and apicolaterally with short digitate lobes; clasper with enlarged 
basal section whose apicomesal angle is obliquely truncate, a small 
appressed appendage posteriorly, apical portion with many spinelike 
setae on mesal surface; aedeagus with an elongate, bilobed, apical 
lip. Female genitalia: cerci rounded; ventrally to cerci a thin, ventrally
