WINTER NUMBER 49 
elevated. General color and other characters as in duryi. Only brachyp- 
terous specimens of duryi and var. confusa known. The principal nervures 
of the elytra strongly costate and the reticulations extremely irregular in 
the variety as well as in the typical form. The third antennal segment in 
duryi only very slightly swollen towards the apex. Described from six 
specimens (short-winged females), collected at Marfa and Chisos Mts., 
Texas, by Mitchell and Cushman. Type, No. 25,186 U. S. N. M., taken at 
Marfa, Texas, June 5, 1908. 
This new variety somewhat confuses our conception of the 
genera Melanorophala of Stal and Hesperotingis of Parshley. 
The tips of the elytra in the brachypterous forms of Stal’s species 
of Melanorophala—clavata, lurida (obscura Parshley), and uni- 
formis—are distinctly divaricate at the apex. If the above spe- 
cies were named correctly by Osborn and Drake, it seems quite 
probable that lurida may not be more than a variety of clavata, 
and wniformis perhaps a synonym of lwrida. However, it is 
probably best to consider Stal’s species distinct until the types 
are examined. The short-winged form of M. infuscata Parsh- 
ley and the long-winged form of duryi are unknown to the writer. 
In short-winged specimens of all the species belonging to the 
genus Hesperotingis (specimens of every described species be- 
fore me), as in M. duryi, the elytra are non-divaricate at the 
tips. The elytra in the macropterous form of H. illinoiensis 
Drake are more broadly rounded at the tips than in similar 
specimens of Melanorophala. Thus, the shape of the third seg- 
ment of the antennae makes duryi fall in the genus Melano- 
rophala and the var. confusa is the genus Hesperotingis. On 
account of the non-divaricate wings of M. duryi it is perhaps 
-advisable to transfer this species to the genus Hesperotingis and 
to treat the two genera as distinct until more specimens of duryi 
and var. confusa, including the males and long-winged forms, are 
secured. The long-winged form of H. antennata Parsh. has been 
described by Parshley. 
Hesperotingis occidentalis n. sp. 
This species is very similar and closely allied to H. illinotensis 
Drake, but easily distinguished from it by the slightly shorter 
antennae, the smaller spines on the head, and costal area contains 
only one complete and partial series of areolae. Length, 5.1 mm. ; 
width, 2.23 mm. 
Brachypterous form: Third segment of the antennae slightly curved 
and a little thicker and more abruptly swollen towards the apex than in 
illinoiensis. Paranota parallel, each composed of a single row of small 
areolae. Rostrum reaching to the meso-metasternal suture. Costal area 
composed of one complete and a partial row of areolae (two rows near the
