PSYCHE. 



[June 1893. 



bred from Nephelodes minians. Two 

 specimens show the whole face and 

 front, even the frontal stripe in some 

 lights, brassy golden ; while the other 

 one shows the facial depression and 

 frontal stripe blackish. They might be 

 identified with Sarc. sarraceniae Riley, 

 but for the fact that the description and 

 figure of the latter show no bush}' hairs 

 on posterior tibiae. This latter charac- 

 ter indicates the species as belonging to 

 the genus Phrissopoda. It is doubtful 

 whether this is Desvoidy's species, 

 however. 



21. Sarcophaga Jicllcis Twns. — 

 Nine specimens bred from " Lachnos- 

 terna" ; nine from Pieris rapae; and 

 two from Le7icania unipuncta. 



22. Sarcophaga oedipodlnis Twns. 

 mss. — Thirteen specimens, bred from 

 Ueliophila unipuncta (?), I cannot 

 actually separate from two specimens of 

 above species sent me by Mr. Scudder, 

 and bred from Dissosteira Carolina 

 captured at Niagara Falls. 



23. Sarcophaga acridida rum Twns. 

 mss. — One bred from "Acrididae." 



24. Sarcophaga sp. $ . — Two from 

 Leucania unipuncta. The species 

 may be recognized by the following 

 brief description : 



Length, 9-10 mm. Face, sides of face, 

 cheeks, and sides of front silvery whitish or 

 cinereous; frontal stripe, antennae, palpi, 

 and legs black; third antennal joint about 

 twice as long as second. Thorax cinereous, 

 with three black vittae, and a shorter one on 

 each side; abdomen marmorate with silvery, 

 cinereous, and black, three blackish vittae 

 showing moderately distinct in an oblique 

 light; anus fulvous. Marginal macrochaetae 

 on third and fourth segments, less closely 



approximated on third segment. Femora 

 ashy below. Venation typical of genus. 

 One specimen, however, has the left apical 

 cross vein bent in at an angle at base, and 

 with a small stump projecting inward from 

 the angle. Both are males, and the front is 

 \ width of head. Row of small bristles on 

 sides of face below near eye margins well 

 pronounced. 



A much smaller $ specimen (6 mm.), also 

 bred from L. unipuncta, has the anus more 

 broadly fulvous, the face with more of a 

 brassy tinge, the front hardly as wide pro- 

 portionally. It is perhaps distinct. 



25. Sarcophaga sp. — One from Leu- 

 cania tinipuncta. It may be described 

 as follows : 



Length, 5J mm. With much the facies of 

 Miltogramma, but arista plumose on basal 

 half. Wholly of a slightly brassy cinereous. 

 Antennae rufous on second joint and base of 

 third, palpi rufous Third antennal joint 

 about ii times as long as second. Front \ 

 width of head, frontal vitta \ width of front. 

 Frontal bristles descending a little below 

 base of antennae, 3 or 4 orbital bristles, a 

 double row of minute bristles on sides of 

 face extending upon sides of front. Vibrissae 

 on oral margin. Thorax brassy cinereous, 

 without distinct vittae. Scutellum with a 

 long apical non-decussate pair of macro- 

 chaetae. Abdomen concolorous, only short 

 bristly, anus tipped with fulvous. Venation 

 typical of Miltogramma (and Sarcophaga}. 

 If this species is found to be undescribed, it 

 may be known as 5. leuca?iiae. 



26. Ormia sp? — A $ bred from 

 Cratnbus. 



27. Lucilia caesar L. — Six bred 

 from Leucania unipuncta. 



Note. — I do not vouch for all of the above 

 flies being true parasites. The hosts as given 

 above are simply taken from the records of 

 breeding sent me with the specimens by 

 Professor Forbes.
