BLATTIDE 
Nine valid species of Blattide are now known from the Gala- 
pagos Islands. All but one are adventive forms, domiciliary 
or adapted to thrive about the habitations of man. 
PSEUDOMOPINZE 
Anisopygia Saussure 
1893. Anisopygia Saussure, Soc. Ent. Zurich, VIII, p. 57. 
From a consideration of the description and figures of jocosi- 
clunis Saussure, genotype of Anisopygia, described from Guate- 
mala, we believe that Temnopteryx snodgrassu McNeill, the 
only known native species of the Blattide found in the Gala- 
pagos, should be assigned to the same genus. 
The following features are shown by snodgrassiu and are 
shared by jocosiclunis so far as we are able to determine from 
the literature. We believe that all will be found to be diag- 
nostic for Anisopygia. 
Interocular space very wide. Tegmina greatly reduced but 
with sutural margins overlapping, anal sulcus obsolete. Wings 
greatly reduced. Dorsal surface of male abdomen with caudal 
margin of penultimate tergite very deeply concave, supra-anal 
plate very strongly and deeply fissate. Ventro-cephalic margin 
of cephalic femora with a row of spines which decrease sud- 
denly in size mesad, those distad being piliform, terminating in 
three heavy distal spines. Pulvilli and arolia present, the for- 
mer on all four proximal tarsal joints. Tarsal claws sym- 
metrical and unspecialized. 
From the above it will be noted that the position of this 
genus is near Chromatonotus Hebard. 
To this genus the Mexican species limbata and sumichrasti, 
described by Saussure’ as metnbers of the genus Temnopteryx, 
show close affinity. The character of the dorsal portion of the 
male abdomen, at least as described for limbata, would appear 
to indicate that they belong, however, to a distinct though 
closely related genus. Females of limbata are in the Hebard 
Collection, but without males we are not able to make a definite 
generic assignment.
