FALL — NORTH AMERICAN SPECIES OF GLARESIS 
25 
Mcndira was descTilwd from Arizona, and lias laaMi taken at Palm Springs and 
Pasadena, ( 'alifornia, liy Ur. Fenyes and iny.self. A Lower (’alifornia specimen 
sent by Mr. Fuelis and labeled mcndira by Horn, is ajiparently a f^ood subspecies, 
differing from the typical form by its slightly more robust form and more dee[>ly 
perforate elytral imnetures. I am unwilling to give it a name without first seeing 
other e.xamples. 
Iiiduclu, described from M'estern Texas, has been eolleeted by Rev. Rirkmann 
at Fedor, in Central 'Pexas, and five .specimens are liow before me. It is jirobable 
that this sjieeies may be .safely identified by its locality label. 
The more important characters of our four species are summarized in the fol- 
lowing table. 
1. Outer margin of hind tibiae deeply emarginate before the a|iex; elytral inter- 
spaees merely slightly convex ....... croKtuta. 
Outer margin of hind tibiae not or but slightly emarginate; elytral interspaces 
more or le.ss distinctly eostiform ........ 2. 
2. Outer apical angle of middle tibiae strongly acutely produceil; prothorax with- 
out a])ieal marginal groove ........ pitornici.t. 
Outer ajiical angle of middle tibiae not strongly produced; post-apical impres- 
sion of jirothorax distinct, at least at sides ...... 3. 
3. Post-apical groove of prothorax (lce])cr at sides, nearly obsolete at middle; ante- 
rior discal impressions wanting; form stouter ..... indurUi. 
Post-a])ical groove distinct from side to side, not much dce[)cr laterally; anterior 
discal impressions distinct; form less robust ..... nundica. 
Certain differences in the armafure of the posterior trochanters and femora 
should here be noticed though I have not thought best to introduce them in the pre- 
ceding table, it being possible that with larger material they may jirove to be in some 
degree variable or sexual in nature. They are however practically constant within 
specific limits in the material at hand, in which it is probable that — in some sjiecies 
at least — both sexes are jiresent. 
In all the species except emstata there is a small spiniform tooth near the outer 
extremity of the jiostero-superior margin of the hind trochanters. 'Phis tooth is 
not visible directly from beneath, being concealed liy the more |)rominent lower 
margin of the trochanter, but may be viewed oliliquely from behind. In ecoxtaia — 
as if to make up for this omission — the lower visible edge of the trochanter bears 
two small rather distant teeth, no trace of which exists in the other three s]iecies, the 
posterior edge of the trochanter being obtusely angulate however in phocnirix. In 
all the species e.xcept phoenicis, the postero-superior margin of the hind femora
