Phasmophaga antennalis n. sp. 



Length, 4.5 to 7 mm. Blackish, cinereous pollinose, except the 

 orange-yellow antennae and arista, the pale yellow palpi, and the red- 

 dish-yellow legs, of which alone the tarsi are blackish ; parafacials more 

 silvery pollinose. Frontalia nearly equilateral. Arista of male a little 

 over half as long as third antennal joint. Tegulae whitish, wings clear. 

 Hind cross-vein irregularly bowed. Apical cell very short-petiolate. 

 The pollen easily detaches from abdomen leaving it blackish in male, 

 brownish-yellow on sides and venter in female. From above the last 

 half of second, third, and fourth abdominal segments appears blackish, 

 but all pollinose from directly behind. 



Type, No. 12618, U. S. N. M. 



Two females and three males all reared, with many others, 

 from Diapheromera femorata^ by Messrs. H. H. and H. C. Severin, 

 the material all being from Wisconsin. The Severins are pre- 

 paring an exhaustive monograph on the subject of the host and 

 its parasites. 



Phasmophaga meridionalis n. sp. 



A collected male, from Piano, Texas, July, 1907 (E. S. Tucker), 

 may best be placed in this genus, but is a very distinct form from the 

 preceding species. It has no discal bristles, and the front is short, 

 not so produced, the frontalia being much widened behind. The arista 

 is longer, being two-thirds as long as third antennal joint ; the petiole 

 of apical cell is not so short, and hind cross vein is straight. The face 

 is fully three-fifths of head-width, and the front hardly narrowed. 



Type, No. 12619, U. S. N. M. 



A male specimen of Phasmophaga in the collection, which 

 seems same as meridionalis, was reared at Cutler, Florida, from 

 Anisomorpha buprestoides, May 29, 1908 (Chittenden, No. 361; 

 Russell, Coll.) It has no discal bristles, the apical cell is short- 

 petiolate, there are two proclinate orbital bristles, the frontalia 

 are equal in width and take up fully one-half the width of front. 

 The arista is scarcely two-thirds the length of the third antennal 

 joint, the face is about three-fifths of head-width, and the hind 

 cross- vein is straight. 



Dissection of one of the females of P. antennalis, that had been 

 left in the breeding cage for some days after issuance, disclosed 

 the characteristic minute eggs of the leaf-ovipositing forms of 

 Tachinids. It is thus certain that the walking-sticks swallow 

 the eggs of Phasmophaga while feeding on the leaves of their 

 food plants. 



The genus is closely related on external anatomical characters 

 to Hypertrophocera and Euryceromyia, less so to Eiithyprosopcu
