April, 1919 Bulletin of the Brooklyn Entomological Society. 43 
species named both have three rows and the last but one. 
Furthermore, tuberosa and harpax both have the cheek vestiture 
black, but in dus it is similar to that of luwzonensis. 
Sarcophaga dux luzonensis n. subsp. 
Male. The characters which distinguish this subspecies from 
others of the group are as follows: two rows of black cilia behind 
the eyes; vestiture of posterior portion of cheeks white, that of 
anterior portion black; first and second genital segment black; 
tip of forceps prong in profile quite blunt, posteriorly with a 
distinct tooth ; posterior spur-like protuberance of distal, posterior 
sclerite of penis small and scarcely differentiated (smallest of any 
of the subspecies). 
Described from three male specimens. Holotype (male) : 
author’s collection. Length: 8-12 mm. 
PHILIPPINE IsLANDS: Mt. Makeling (holotype); Malinoa, 
Tayabas; Los Banos (C. F. Baker); Austratra: Queensland, 
Townsville (F. H. Taylor). 
The specimen from Australia is small and not quite typical. 
There is a partial third row of black cilia behind the eyes, and 
the forceps do not exactly correspond, but there is no reason to 
regard it as anything other than an atypical specimen without a 
considerable series of specimens to compare. 
These subspecies are also interesting because of their distribu- 
tion; one or more of them are known from each continent except 
South America. A brief summary of distribution is here given. 
The information is based on occurrence as given by Bottcher 
(Deutsche Entomologische Zeitschrift, 1912 and 1913), Aldrich 
(“Sarcophaga and Allies,’ 1916) and determinations made by 
author.
