1914] Willard—S pecies of Platypeza 167 
September, or about the time of the early rains. These larve, 
which proved to be the immature stages of an undescribed species 
of Platypezide, are cylindrical, soft, and cream colored. The 
body tapers anteriorly and the first segment is rounded. The 
surface of the body is rough, covered with many small spines. 
Each segment, except the first, second and last, is provided with 
two large, lateral, and two smaller, dorsal, segmented, spiniferous 
appendages. The second segment has only dorsal sete; the last 
segment has two pairs of lateral setze and one posterior pair. The 
anterior margins of the first, third and twelve segments are each 
provided with a pair of short tube-like processes. The ventral 
side of segments five to eleven have a pair of papilla near each 
lateral margin. The slit-like anal opening is on the ventral side 
of the twelfth segment. 
The pupa is dark brown in color; oval, flat, hard and wrinkled. 
The appendages are the same as in the larva. 
Some of the adult flies were sent to Professor J. M. Aldrich, 
who kindly examined them and said they belonged to an unde- 
scribed species. He sent several specimens of still another 
undescribed Platypeza, which he reared from the shelf-fungus, 
Polyporus, while at Stanford in 1906. The descriptions of the 
two species follow. 
Platypeza agarici sp. nov. 
Male: Velvety-black. Head black; antenne black; face grayish in middle; 
cheeks black, with black hairs. Eyes contiguous, divided, upper half reddish- 
brown, with large ommatidia, lower half black, with small ommatidia. Thorax 
black with black hairs. Abdomen velvety black; last segment and a narrow mar- 
gin on the incisures, grayish. Sides and back with black hair. Legs black; tarsus 
brown with fuscous pile; hind tarsal joints flattened; the third joint is the longest 
and broadest; halteres black. Wings hyaline; subcostal cell of a yellowish tinge; 
veins brown; anterior branch of 4th vein well arcuated; the posterior branch 
reaches to the border of the wing; 2nd posterior cell short; posterior cross vein 
removed from border of wing on 5th vein by twice its own length. An interest- 
ing variation occurs in the cross vein between the first and second basal cell. 
Always faint, it is entirely lacking in some specimens. 
Female: Eyes separated and not divided. Abdomen velvety black. Length, 
23-33 mm. 
Platypeza polypori sp. nov. 
Male: Velvety black. Head black; face black, grayish toward ventral margin; 
cheeks black with black pile; antennz black; eyes contiguous, divided; the upper
