Studies in Fruit Flies. Part I. Dacini — Hardy and Adachi 
171 
We have studied a series of specimens from 
Amboina, Jan., 1908-May, I 909 (F. Muir); 
from Rabaul, New Britain, Oct. -Nov., 1949, 
ex "Aila,” Inocarpus edults (N. L. H. Krauss); 
Guadalcanal, Nov., 1944 (C. O. Berg); Te- 
naru River, Guadalcanal, Jan., 1945 (G. E. 
Bohart); Solomon Islands, July-Aug., 1909 
(W. W. Froggatt). 
Dacus (Strumeta) hochii (Zia), n, comb. 
Fig. 12 
Stmdacus hochii Tl'd., 1936, Chinese Jour. Zool. 
2: 157. 
Callantra {Sinodacus) hochii (Zia), Hering, 
1952 , Naturf. Gessell. in Basel, Verhandl. 
63: 43. 
This species has been considered as belong- 
ing to a distinct subgenus (genus of authors) 
under Callantra. It appears to us that this 
should be treated under Dacus {Strumeta), 
The abdomen is more noticeably stalked than 
in most Strumeta, but in other details (as given 
under our concept of Callantra) it more nearly 
fits Dacus {Strumeta)i The antennae are typical 
of this group; the first abdominal segment is 
broader at its apex than at its base, and the 
lateral humps are not unusually strong; the 
abdomen is not as strongly arched, and the 
sclerite between segments three and four is 
straight. Zia defined her Sinodacus as having 
no prescutellar bristles (based apparently upon 
one specimen). The material which we have 
studied, from the type locality, has prescutel- 
lars. Hering (1952^.' 43) said that his spec- 
imens, from Sumatra, had a prescutellar on 
one side but not on the other. 
The species is readily recognized by the 
absence of postsutural yellow vittae on the 
mesonotum, by the large brown spot covering 
the apical portion of the wing (Fig. 12), and 
by the transverse black band across the face. 
The mesonotum is chiefly rufous with no 
black markings and with a small yellow spot 
in the median portion just behind the suture. 
Length: Body and wings about 7.0 mm. 
TYPE locality; Hainan, China.

Location of type not known by us. 
Hering (1952^.' 43) recorded this from 
Sumba Island and Java. We have not seen 
it from this region. Our specimen is from 
Hainan Island, S. China, No-doa, Tan-Hsien 
District, Mar. 18-22, 1935 (F. K. To). 
Dacus (Strumeta) impunctatus 
de Meijere 
Dacus impunctatus de Meijere, 1914, Tijdschr. 
V. Ent. 57: 188-189. 
This species appears to fit very close to 
D. mcgregori (Bezzi). From the original de- 
scription it seems to difler by having the 
thorax predominantly black. If it is a distinct 
species it no doubt lacks the peculiar bulla on 
the wing which is so distinctive of mcgregori. 
Length: Body, 4.0 mm.; wings, 3.5 mm. 
TYPE LOCALITY: Semarang, Java. 
Type in the Zoologisch Museum, Am- 
sterdam. 
We have not seen this species. 
Dacus (Strumeta) latifrons 
(Hendel), n. comb. 
Fig. 13 
Chaetodacus latifrons Hendel, 1915, Mus. Nat. 
Hungarici, Ann. 13: 425-426. 
This species is readily recognized by its 
all-rufous abdomen; by its broad front (ap- 
proximately as broad as one eye and just 
slightly longer than wide) (Fig. 13^), and by 
having the costal band rather narrow but ex- 
panded at the apex (Fig. 13^); also by the 
very distinctive trilobed apex of the ovipositor.
