98 THE BLATTIDAE OF PANAMA 



This Species is extremely close to E. mexicana Saussure and may 

 eventually prove to be a geographic race of that insect. The 

 tegmina with humeral \'ein showing no darker blotches is the most 

 striking difference in coloration for colomhiana. Saussure's figure 

 gives a very good idea of the markings characteristic of this insect.

The type is more intensive in coloration than the material here 

 recorded, or specimens from Mexico and Guatemala before us. 



HYPORHICNODA new genus 



The present genus shows close relationship to Rhiowda Brunner, 

 differing in the greater reduction and different type of limb arma- 

 ment, ^-'^ in the wings of the male which show a more strongly Poly- 

 phagine tendency, absence of both tegmina and wings in the female, 

 and in the medio-longitudinal carina, which is distinct on pronotum 

 and mesonotum in the male and decided on pronotum, mesonotum 

 and metanotum in the female. 



Genotype: Ilyporhicnoda reflexa [Rhicnoda reflexa] (Saussure 

 and Zehntner). 



Generic Description. — Sexes very dissimilar. Male with fully 

 developed tegmina and wings, smaller than female, which lacks 

 organs of flight. Head with surface of occiput polished but show- 

 ing impressed punctae mesad, interocular-ocellar area depressed, 



120 ^n immature specimen of the genotype, Rhicnoda rugosa Brunner, from Goenong 

 Soegi, Lampong, Sumatra, is in the collection of the Academy of Natural Sciences. This 

 specimen has the ventro-cephalic margin of the cephalic femora armed with (five) mod- 

 erately elongate, heavy spines, succeeded by a row of minute spines, which are closely 

 placed distad, terminated by a single heavy spine; the ventro-caudal margin of the 

 cephalic femora and the ventro-cephalic margin of the median and caudal femora are 

 armed with (three and one distal) moderately elongate, heavy spines. The ventro- 

 caudal margin of the median and caudal femora are armed with (median four and one 

 distal; caudal three or four and no distal) shorter and lighter spines.
