HUNTER: PARASITIC INFLUENCES ON MELANOPLUS. 207 
material in his collection. He wrote that the description by 
Townsend was not then accessible. Upon looking up the list of 
types in our collection, I found the material, a male and a female, 
upon which Townsend based his description. A careful comparison 
with literature at hand, made by Dr. Williston, shows the three 
specimens to be without doubt identical. It is interesting to 
note, as showing the range of adaptability of this species, that 
the types were bred from cocoons of Cimbex Americana. 
Here follows Dr. Hough’s description: 
Sarcophaga (Tephromyia) hunterinov. sp. Three malesand two females, 
bred from J/elanoplus differentialis by Mr. S. J. Hunter in whose honor I 
have named it. Habitat Kansas. 
Length five and one-half to seven millimetres. Color gray; the 
male rather brownish, the female whitish. Abdomen without the 
usual variable spots of a Sarcophaga but with three black stripes, 
a median and on each side a lateral; in the female the lateral stripes 
are quite faint and can only be seen well 
with a favorable incidence of light. Anal 
segments gray, retracted within the fourth 
segment in the males. Palpi yellow to 
yellowish brown. Antenne brown with 
the apex of the second joint and the base of the third yellow toa 
varying extent. Squamule white. Wings grayish hyaline; first 
longitudinal vein not spinose, third spinose for two-thirds to three- 
fourths of the distance to the small cross vein. Legs black; in the 
male more or less brownish gray pollinose, in the female whitish 
gray pollinose. Hind tibiz of male not bearded. 
Head—Front of male at narrowest point one-sixth the width of 
the head, from this point which is about at the junction of the dor- 
sal and middle thirds the front widens both dorsad and ventrad. 
Front of female of uniform width, six-twentieths the width of the 
head. The exact measurements are: Male front 0.4 mm., head 
_ 2.5; female front 0.6 mm , head 2.0 mm. 
Antenne—Third joint more than twice as long as the second. 
Arista fully as long as the second and third joints together, com- 
posed apparently of but two joints of which the basal is very small 
and about as long as broad, the terminal tapering as usual (its 
basal and apical thirds biack, its middle third whitish) and feathered 
for rather more than half its length with rather long, fine hairs. 
The yellow, or perhaps I should say reddish yellow, color is more 
extensive on the antenne of the female than of the male.
