Pacific Species of Pulvilligera — MlLLIRON 
349 
of Evelyn River, Guadalcanal, August 23, 
1944 (H. E. Milliron). Specimen in the col- 
lection of the U. S. National Museum. 
allotype: Female, with the same data 
as the male mentioned above except that it 
was reared August 25, 1944. Specimen in 
the collection of the U. S. National Museum. 
TYPE: One of six males, probably in the 
Zoological Museum, Berlin, Germany. Type 
not examined. 
type locality: Taihanroku, Formosa. 
host: Seeds of Pandanus upoluensis Mar- 
telli. (In the Solomon Islands.) 
distribution: Formosa and Guadalcanal. 
ADDITIONAL SPECIMENS EXAMINED: The 
writer also has studied a series of 86 males 
and 83 females, Mouth of the Evelyn River, 
Guadalcanal, 23 Aug. 1944, (H. E. Milliron). 
Ex seed of Pandanus. These are a part of the 
same lot as the above male and allotype fe- 
male, and all were reared between August 23 
and September 9, 1944. The Pandanus was 
later identified as P. upoluensis. The entire 
series is contained in the collection of the 
U. S. National Museum, 50 being preserved 
in alcohol. 
variations: Male: The lightest specimens 
are predominantly brownish- (and greenish-) 
yellow with reddish-brown over most of ab- 
dominal terga IV-VI inclusive, the black 
markings being reduced on the head to the 
area surrounding the ocelli and along a nar- 
row line from the lateral ocellus to the com- 
pound eye, as well as narrowly around the 
foramen magnum. There is only a faint in- 
dication of the lateral spot above the eye (of 
the three spots on the vertex and temples). 
The three longitudinal stripes on the dorsum 
of the pronotum are reduced to separate elon- 
gate spots posteriorly, the median one being 
the faintest. Only an elongate black spot ap- 
pears on the mesonotum, the remainder show- 
ing only faint traces of longitudinal black 
stripes. The propodeum is without trace of 
infuscation. The basal abdominal tergum 
(III) is blackish only at the base, and terga 
IV-VI inclusive have only a slight indication 
of any black lateral spot above. All legs are 
yellowish. 
The darkest male has pronounced black 
markings much as described but more intense 
and extensive. Most of the face below, except 
laterad of the clypeus and the area bordering 
the eyes in front, is very dark. The lateral 
spot above the eye is triangular, more en- 
larged, and extends down a considerable dis- 
tance on the temples. The median spot ex- 
tends posteriorly and unites with the black 
around the foramen magnum. A blackish ex- 
tension appears on the front above, extending 
forward from the line described between the 
lateral ocellus and the compound eye. The 
lighter parts of the head are brownish to 
brownish-yellow. All lighter areas of the 
thorax are deeper than that described for the 
typical male, and there are three distinct dor- 
sal longitudinal black stripes, the lateral one 
extending to the axilla and the median at 
least to the transverse line on the mesoscutel- 
lum (in some cases noticeably beyond) , being 
only slightly interrupted at the anterior mar- 
gin of the mesoscutellum. The front and 
hind coxae are blackish and the exterior sur- 
face of the hind femur is infuscated. The 
abdomen is much as described but the bands 
described as amber are black, and tergum VI 
is reddish-brown. 
Between these two extremes all color gra- 
dations occur, but structurally there seems to 
be little variation. Larger, more robust males 
may be found with more distinct "verticil- 
late” antennae and a few more conspicuous 
bristles on the proximal two-thirds of the sub- 
marginal vein (14-15). Males vary in size 
as follows: length 8.8-13.7 mm.; abdomen 
3. 8-5. 3 mm. 
Female: Females vary in color as do the 
males. The palest specimen is predominantly 
brownish- (or greenish-) yellow with black 
markings reduced on the head to the area 
around the ocelli and three spots on the ver- 
tex, with very little infuscation elsewhere.
