[Dec. 
moderate, triangular; palpi slender (in genus). Pro- 
thorax small, quadrate, just wider than long (by measure- 
ment) ; pronotum with usual anterior and posterior trans- 
verse impressions ; median longitudinal impression 
vague; surface rugose. Elytra obliquely sinuate-trun- 
cate at apex (more widely than usual) ; each with a small 
tooth at sutural angle; surface with micro sculpture like 
labrum, and also moderately punctate, most of the punc- 
tures being rather small and separated from each other 
by much more than their own diameters; a few larger 
punctures, some bearing small hairs, scattered in basal J 
of disk and widely spaced in one line on each elytron 
parallel to suture to within \ of apex. Lower surface of 
body not distinctly punctate and not pubescent except 
for setae on all coxae and pairs of setae on 4th and 5th seg- 
ments of abdomen; 6th ventral (c?) deeply emarginate, 
without hairs (some hairs present on apparent 7th seg- 
ment) ; thighs without hooked hairs. Inner wings fully 
developed. Male with 3 basal segments of front tarsus 
slightly dilated, white, and pubescent below (outer seg- 
ments slender, dark) ; male genitalia as figure. 
Length 8 ; width c. 2J mm. 
Holotype S and one S paratype, both from north side 
of Milne Bay, eastern tip of New Guinea, December 1943, 
taken by myself ; ecological habitat not recorded. Types 
in Museum of Comparative Zoology: Type No. 27735. 
To understand the relationships and geographical sig- 
nificance of this new species, one must understand first 
the previously known distribution of Prothyma. The 
genus in the strict sense includes some 50 species, of 
which a few are in Africa, many in Madagascar, 2 on 
Mauritius and Reunion, many in the Oriental Region 
east to Java and the Philippines, one in temperate China 
(W. Horn, 1935, p. 24), and one in southern Mexico in 
the edge of the American tropics. Until now, no Pro- 
thyma in the strict sense has been known east of Wal- 
lace ’s Line, but endemic subgenera, each with one or two 
species, are localized in Celebes, northwestern Australia 
(W. Horn, 1936, p. 22), New Caledonia, and Samoa (W. 
Horn, 1934, p. 144). These subgenera are marked either
