Harpagomyia genurostris (Leicester) 1908 
Our pupal specimens of this species from 
Saidor, Northeast New Guinea, w r ere lost due 
to breakage in shipment, hence a complete de- 
scription cannot be given. However, this is 
the only species of the genus known from New 
Guinea so the generic diagnosis should be suf- 
ficient to place any specimens from the island. 
The species has been partially described 
but inaccurately figured by Jacobson (1911: 
16 1 ) and De Meijere (1911: 164) from the 
Dutch East Indies and partially figured but not 
described by Bohart and Ingram (1946: 54) 
from Okinawa. The following descriptive notes 
have been translated and rewritten from De 
Meijere. 
Cephalothorax. — Behind the upper eye- 
spot stands a long double hair (median post- 
ocular seta), which beyond the middle shows a 
strong bending; under the eye one finds a much 
shorter, simple or double seta (upper post- 
ocular). The thorax also bears in front two 
short double hairs, one behind the other (upper 
and lower anterothoracic ) . On the middle, also, 
are the respiratory trumpets. These are long, 
in the upper half almost entirely of equal 
width, straight truncate at the end, and with 
a few deep incisions on the inner side. 
Abdomen. — On the last abdominal segment 
are the customary, well-developed, multifid fan- 
hairs (A-VIII). The dorsum always shows 
more hairs close to the corner, which are mostly 
sessile, those lying on the lateral sides (evi- 
dently seta b) are particularly long and surpass 
the next following segment in length. The next 
to the last and the last segments always bear 
a multifid fan-hair on the posterior outer corner. 
The paddles are little pigmented, with an incon- 
spicuous midrib, long and acuminate apically, 
terminal seta missing, the margin is extremely 
fine-toothed on the medial side only, the rest 
smooth. The abdomen is yellow-white, while 
on the back it has a characteristic black pat- 
tern. 
PACIFIC SCIENCE, Vol. Ill, January, 1949 
Genus HODGES1A Theobald 
Diagnosis. — Readily distinguished from all 
other mosquito pupae by the form of the trum- 
pets, which are described by Wigglesworth 
(1929: 60) as follows: 
Trumpets small and of highly characteristic 
structure, being cleft almost to the base in the 
form of two leaflets. Outer leaflet four times as 
long as its average width, with more or less 
longitudinal strigulae and with numerous mi- 
nute scale-like denticles on the outer surface. 
Inner leaflet only half the width of the outer 
and with a bifid tip; it has the same longitu- 
dinal or oblique strigulation, but is without the 
minute denticles of the outer leaflet; its an- 
terior margin and tip are clothed with fine 
hairs and the posterior margin is reflected in- 
wards away from the outer leaflet. 
The cephalothoracic and almost all the ab- 
dominal setae are small and inconspicuous. The 
dorsal seta (8) of the cephalothorax is placed 
in front of the trumpets. 
The pupa of none of the three New Guinean 
species has been described. 
Genus URANOTAENIA Lynch- Arribalzaga 
Diagnosis. — As in culicine genera the inner 
wall of the trumpet is not separated from the 
outer (in contrast to Harpagomyia), and the 
following features are found in the abdominal 
chaetotaxy. Setae H and K close together, but 
well apart from L and M; s somewhat larger 
than these; the float-hair usually large and den- 
dritic. Seta 2 -II long, markedly longer than 
other setae of the segment. Setae A-III through 
VI small and spine-like; A-VII and A-VIII very 
variable according to the species. Segment IX 
always with a small seta on its posterolateral 
corners. 
Discussion. — As noted by Edwards (1941: 
364) it is surprising that the pupal stage of 
Uranotaenia is not better defined in view of 
the distinctive position of the genus on adult 
characters. Perhaps the readiest means of diag- 
nosis is the pair of setae on segment IX which 
are always at least equal to the length of that 
segment; these setae are also present in Aedo-
