34 THE BLATTIDAE OF PANAMA 



Color. — Surface smooth and shining. Head deep bay, ocellar spots minute 

 buffy dots, antennae bay except proximad where they shade to buffy. Pronotum 

 entirely blackish bay, except lateral margins which are ochraceous-buff tinged with 

 ochraceous-tawny, these broadest toward latero-caudal portions of disk. Mesono- 

 tum, metanotum and first abdominal segments tawny, this continued mesad on 

 each side of the three succeeding segments as a broad suffusion into the remaining 

 darker, blackish brown, dorsal surface of the abdomen, with the exception of a 

 brief lateral area on each side of the sixth and seventh segments of light ochraceous- 

 buff, these forming a very distinctive buff marking latero-caudad, without, but just 

 preceding, the cereal bases. Tegmina blackish bay distinctively marked with 

 ochraceous-buff, the borders of these pale areas ochraceous-tawny ; pale in proximal 

 half of anal field, entire marginal field continuing beyond along the costal margin to 

 median part of tegmina by invading the scapular field, and a large oval area mesad 

 in the scapular field, the axis of which is oblique. Wings buffy, heavily suffused 

 with prout's brown in distal two-fifths of anterior field, branches of axillary vein 

 prout's brown, distal portion of radiate veins tinged with this color. Limbs buffy, 

 with spines and tarsi tawny. Cerci cinnamon brown. 



Length of body, 9; length of pronotum, 3.2; width of pronotum, 4.3; length of 

 tegmen, 6.5; width of tegmen, 2.95; length of cercus, 1.9; length of caudal tibia, 

 3.55; length of caudal metatarsus, 1.65 mm. 



The type is unique. 



EUDROMIELLA new genus 



The single known species of this genus suggests, in its form and 

 deHcate structure, species of the genera Euthlastoblatta Hebard and 

 Rhytidometopum, here described. The biHneate pronotum is a 

 type famiHar in Blattella germanica (Linnaeus) and many other 

 species of the Group BlattelHtes. 



This genus shows nearest affinity to Latiblattella Hebard, differ- 

 ing in the characters of major importance In having the form not 

 as broad; the vertex well rounded, not slightly flattened; the face 

 more convex; both sexes with equally fully developed organs of 

 flight; the tegminal discoidal sectors decidedly, not moderately, 

 oblique; the costal veins of the wings heavily, not very weakly or 

 hardly at all clubbed distad, and the male abdomen less decidedly 

 constricted beyond the specialized sixth dorsal segment. 



In linear arrangement this genus comes after Aglaopteryx Hebard 

 and before Latiblattella Hebard. This is a complex type, sharing 

 features with many diverse genera, such as are so often found 

 among the Blattidae. 



The genus is monotypic. Genotype: Eiidromiella bicolorata 

 new species.
