10 INSECUTOR INSCITlit MENSTRUUS 



Phobolosia brimleyana, new species. 



Gray ; fore wing with dense metallic black thick strigae ; lines black- 

 ish, rather approximate, smooth, the inner line somewhat indistinct, the 

 outer slightly excurved over cell ; a round, deep black patch at the end 

 of the cell ; subterminal line indicated, pale, wavy ; black costal dashes 

 before the apex, continuing the narrowly broken black terminal line. 

 Hind vsing gray with black terminal line as on fore wing. Tip of abdo- 

 men metallic black. Expanse, 1 4 mm. 



Type, female, No. 1 8 1 66, U. S. Nat. Mus. ; Raleigh, North Caro- 

 lina, September 8, 1907 (C. S. Brimley). 



The species is close to grandimacula Schaus, which is rather unex- 

 pected, considering the distribution. 



NEW MUSCOID FLIES, MAINLY HYSTRICIID^E AND 

 PYRRHOSIIN>E FROM THE ANDEAN MONTANYA

It is probable that Tropidopsis and Parag^mnomma will prove to 

 possess colored maggots. Perhaps all of the spinelike macrochaetae forms 

 will show such maggots. Gabanimyia has subspinelike macrochaetae 

 and colored maggots somewhat like those of Eug^mnochaeta. Thus 

 there will probably prove to be in the Pyrrhosiinae a series of groups of 

 colored maggot forms, some with spinelike macrochaetae and some with- 

 out, as occurs in the Hystriciidae. It is believed that none of these has 

 the leaf-larviposition habit. 



Heretofore these flies have been quite easily distinguished from the 

 Hystriciidae in general by their much less saJient epistoma, in marked 

 contrast to the older and better known forms of that family, but many 

 recently discovered forms that appear to be referable only to the Epal- 

 pini show the same type of epistoma. It further develops that certain 

 types of Pyrrhosiinae exist with a remarkably projected epistoma, quite 

 equalling that of any Hystriciid and surpassing many of them. So far 

 these types appear to be restricted to the high altitudes of the Andes, 

 above 1 1,000 or 12,000 feet. They can be sepjirated from the Hys- 

 triciidae only on uterine and maggot skeleton characters. The Pyrrho-
