NEW COCKROACHES—ALBUQUERQUE 493 
M. maximiliani (Saussure) is quite distinctive in its brown tegminal 
dots and male genital characters. 
Mate: Size large and form broad for the group. Interocular space 
narrow, divergent toward vertex and equal to one-fourth width be- 
tween antennal sockets. Ocellar spots distinct. Maxillary palpi 
elongate, slender; antepenultimate and penultimate segments sub- 
equal in length, ultimate segment slightly longer. Pronotum trans- 
verse, with convex lateral margins; greatest width slightly caudad of 
median line. Tegmina and wings well developed, extending beyond 
the cercal apices. Veins of tegmina very numerous. Radius vein 
with 10 to 12 branched rami. Media and cubitus each with a basal 
fork. Media with about 12 apical rami. The posterior branch of 
cubitus has 2 apical rami. Seven anal veins. Wings with 6 ramified 
rami of radius (5 anterior and 1 apical). Media simple. Cubitus 
vein with 5 formed branches that go to the margin. Intercalated 
triangle small. Supra-anal plate triangularly produced between cerci 
with rounded apex. Subgenital plate asymmetrical as shown in figure 
4. Cephalic femora with ventrocephalic margin armed with a series 
of spines which decrease gradually in length mesodistad and terminate 
with 3 increasingly longer distal spines. Pulvilli and arolia moderately 
developed. T'arsal claws heavy, unspecialized. 
Frmaie: Agrees with male except in the following features: 
Size somewhat larger and broader. Interocular space slightly wider 
and divergent toward vertex, with slightly more than a third the 
distance between antennal sockets. Tegmina and wings somewhat 
reduced not exceeding cercal apices. Supra-anal plate triangularly 
produced between cerci and strongly bilobate at apex. Subgenital 
plate simple, free margin strongly convex and rounded, forming at 
apex a brief longitudinal carina. 
Head ochraceous buff, with a dark brown band extending from the 
interocular area to lJabral suture. Antennae and mazxillari palpi 
ochraceous buff, with light brown suffusion mostly on ultimate seg- 
ment. Pronotum with two broad mesolateral longitudinal bands of 
brown, slightly divergent toward anterior margin, broader mesad 
and caudad but remain separate at caudal margin. Area between 
these bands and lateral margins ochraceous buff. Tegmina translucent 
with veins tinged with brown mostly on basal half of radius, media, 
and cubitus veins and on anal veins. Following radius vein distad 
are some black dots (about four) of different sizes and shapes. Dorsal 
surface of abdomen and legs cinnamon brown.

pronotum, o 4, 9 3.8; width, o& ? 5.8. Length of tegmina, o& 20,
