DESCRIPTIONS OF NEW SPECIES AND VARIETIES. 89 



This species appears to belong to the subgeuus Exorista of Meigen, closely allied to 

 Tacliina proper, ami differing from it chiefly in having the eyes hairy, and iu the pres- 

 ence of bristles on the middle, as well as at the hind margin of the second and third 

 abdominal segments, whereas Tacliina has only the latter. [Fourth Rept., p. 40-41. 



This species was simultaneously published by Dr. LeBaron in his 2d 

 Rept. lus. 111., p. 123. It is retained in Exorista by Osteu Sacken. 



ANTHOMYIA ZEAE 9, N. Sp. (PI. 2, Fig. 24). Length 0.20 [inch, = 5 mm ] ; alar ex- 

 panse 0.38 [inch, =9.5"""]. Antenna- black ; style microscopically pubescent; front, 

 fulvous, with a distinct, rather narrow, brownish, cinereous margin ; face and orbits 

 brownish-white ; palpi and proboscis black ; ocellar area somewhat heart-shaped ; 

 thorax and abdomen pale yellow-brownish cinereous, with minute black points at the 

 insertion of the bristles ; thorax with an indistinct middle stripe of brown ; legs black, 

 tinted with cinereous ; poisers pale ochre-yellow ; scales small, the upper valve larger 

 than the lower. [First Rept., p. 155. Figs. 86, 87, and PI. II, Fig. 24. 



ANTHOMYIA RADICUM (Linn.) var. CALOPTENI Egg Oval, smooth, white, 0.04 inch 

 long. 



Larva Skin unarmed, 0.24 inch [ =6 mm ] long when extended, of the normal form, 

 the maudibular hooks black, quite conspicuous, and diverging at base. Prothoracic 

 spiracles elongate. Anal spiracles minute, yellowish-brown, with the 8 fleshy sur- 

 rounding tubercles, small. 



Pupa Pale-brown, rounded at each end, with the prothoracic spiracles and lips an- 

 teriorly, and the anal spiracles and lower tubercles posteriorly, showing as minute 

 points. 



Imago 9 Average expanje 0.48 inch [ = 12"']. General color ash-gray with a fer- 

 ruginous hue, especially above, and a more or less intense metallic reflection. Face 

 with white reflections below ; eyes smooth, brown, encircled by the ground color, and 

 this behind and on forehead bordered by a brown line ; 2 similar lines at back of head 

 from upper corners of eyes and approaching to neck ; forehead dusky-brown, becom- 

 ing bright yellowish-red toward base of auteun;e, and the brown forking at right 

 angles around occiput. Trophi and antenme black, the style simple and somewhat 

 longer than the whole antenme. Thorax with three dusky longitudinal lines, obso- 

 lete behind ; legs black, with cinereous hue beneath ; wings faintly smoky, with 

 brown-black veins, the discal cross-vein straight and transverse, the outer one bent 

 and more oblique; balancers crumpled, yellowish. Abdomen with faint dusty medio- 

 dorsal spots, broad at base, tapering and obsolesciug toward end of each joint. 



In the $ , aside from the larger eyes, stronger bristles, and narrower, less tapering 

 abdomen with its additional joint all characteristic of the sex the face is whiter, 

 and the medio-doreal dark mark of abdomen continuous. 



Described from 25 specimens of both sexes, reared from locust-egg-feeding larvte. 



Specimens bred from cabbage and radish roots, and others in my cabinet taken 

 from the burrows (made in Osage Orange iu Missouri) of Crabro stlrplcola Pack. ; do- 

 not differ specifically. [Ninth Rept., p. 95.

 where the species is shown to be the Anthomyia angustifrons of Meigen. 



ORTHOPTERA. 



CAXOPTENUS ATLANIS N. sp. Length to tip of abdomen 0.70 0.85 inch [=17.5 

 21 mm ]; to tip of closed wings 0.92 1.05 inches [=23 2G"' m ]. At once distinguished 

 from femuf-riibrum by the notched character of the anal abdominal joint in the male 

 and by the shorter, less tapering cerci ; also by the greater relative length of wings 

 which extend, on an average, nearly one-third their length beyond the tip of the ab- 

 domen in the dried specimens : also by the larger and more distinct spot on the wings 

 in all which characters it much more closely resembles spretus than feinur-rubnim.
