by de Meijere (Tijd. v. Ent. liv. p. 77, 1911). It is also 
nearly allied to P. constmilis, Brun., but seems to be distinct. 
Pachyrrhina virgata, Coq. 
Arisan, 8000 ft., 10. x. 1912 (7. Nitobe), 2 2. 
There are some divergences from Coquillett’s description 
which are probably due only to the difference of sex, Co- 
quillett describing only the male. The female has been 
recorded, but not described, by Alexander (Can. Ent. xivi. 
p. 163). In the present specimens the abdomen is mainly 
dark brown above, the base and apex of the first segment, 
the ovipositor, the whole venter, and the margins of the 
tergites, especially towards the base of segments 2—4, being 
yellowish. In one specimen the dull brown spot at the tip of 
the lateral thoracic stripe is distinct, making the stripe appear 
bent downwards at the tip ; in the other it is not distinctly 
so; this species would therefore seem to connect the group in 
which the lateral stripe is bent with that in which it is not. 
Pachyrrhina javensis, Dol. 
A male from Kotosho Island, near Formosa, 20. vil. 1912 
(T. Shirakt), 
Osten-Sacken and Brunetti have both referred to the small 
size of the discal cell as one of the distinguishing characters 
of this species. It may also be noted that in the present 
specimen and in a male from Trincomali, Ceylon (Lt.-Col. 
Yerbury), the radial sector is extremely short, shorter even 
than the descending portion of R,,;, and only about half as 
long as the stigma. In some females from Ceylon which I 
refer with a certain amount of doubt to this species, the vena- 
tion is similar except that Rs is not quite so short. In all 
these specimens a noteworthy feature, previously overlooked, 
is that the stigma is devoid of hairs. As in most of the 
species of this genus, Sc; is present, though shorter than 
Sc,; the area of the costal cell between Sc, and R, is in this 
species concolorous with the dark stigma. 
Pachyrrhina parva, sp. n. 
Head entirely orange; upper surface of rostrum shining ; 
front considerably swollen. Antenna little longer than the 
head and thorax together, 13-jointed, the last jomt minute; 
scape and first flagellar joint orange, remainder dark brown. 
Intermediate flagellar joints with well-marked basal enlarge- 
ment and median emargination on the underside, upperside
