COLOMBIAN DERMAPTERA AND ORTHOPTERA 
cephalic margin ariiicd with a long row 
inicroscoiiic, ])ilitorni spines, terininatin 
of closely placed, short, 
a: in tw’O elongate distal 
spines, of which the more distal is slightly the longer; ventro- t 
caudal margin supplied with an elongate spine distad. Median 
and caudal femora supplied on all ventral margins with elongate 
hairs and a single elongate distal spine (and in addition from 
none to one elongate spines). Caudal tarsi with fourth joint 
alone supplied with a pulvillus, which occupies its entire ventral 
surface. Tarsal claws asymmetrical, unspecialized. Arolia verj^ 
large. In these three latter features agreeing with Lissoblatta, 
but also with Chorisoneiira. 
Asemoblatta nana new species ( Plate VIII, figs. 1 to 3; plate X, figure 28.) 
The affinities of this diminutive and anomalous species are 
discussed under the generic treatment. 
Type. — cf; Bogota, Cundinamarca, Colombia. Elevation, 8750 
feet. November 24, 1914. (PTom A. Alaria.) [Hebard Collec- 
tion, Type no. 542.] 
In addition to the features given in the generic discussion, we would add 
the following. Interocular space slightly wider than that between the an- 
tennal sockets. Maxillary pali)i with enlarged fifth (distal) joint subec|ual 
in length to fourth, longer than third. Pronotum with cephalic margin 
evenly convex to the latero-caudal angles. 
Tegmina slightly reduced, reaching to base of supra-anal plate,' anal sulcus 
very inconspicuous, (nine) costal veins well spaced, without intervening 
si)urious veinlets, delicate discoidal sectors oblique (three in sinistra! tegmcn; 
none in dextral tegmen, which area is concealed when the tegmina are at 
rest). Wings atrophied, represented by elongate-oval lateral pads, extend- 
ing slightly beyond caudal margin of metanotum, showing only a heavy, 
bifurcated discoidal vein. Sixth tergite highly specialized mesad,®ina large 
dei)ression there found a transversely convex ridge occurs with cei)halic face 
sui)plied with a tuft of agglutinated hairs directed cephalad. 
Supra-anal plate triangular with apex bluntly rounded, in length two- 
thirds i)roximal width. Subgenital plate Plectopteroid, with two heavy, 
cylindri(!al, convergent styles, situated in deei)ly inset sockets, these st 3 ’les 
about twice as long as wide with apices tapering, the sinistral thickened 
f-hroughout, slightly shorter and heavier in distal half than the tlextral. The 
median section of the subgenital plate is narrowly triangularly produced, 
directed oblicpiely dextrad and ju’e.ssed between these stjdes. 
^ So called generally in descriptions of the Blattidae, it is actuallj' the ninth 
tergite; the tenth, or true supra-anal i)late disappears in this famib' before 
the adult condition is reached. 
® t)f the same type as in TAssoblattn, but more decidedb' developeil.
