Roth — Cockroach Genus Gurneya 
297 
on both margins of mid and hind femora. 2 Tarsal claws equal, 
arolia and pulvilli well developed. Right and left paraprocts shown 
in figures 27 and 28. Genitalia as shown in figures 29-32; L2d is 
a flat unevenly sclerotized plate separated from L2vm (Figs. 29-30) ; 
prepuce highly modified with an area of densely packed small setae 
leading into a large smooth, banana-shaped (when flattened) sclero- 
tized plate (Fig. 30). R2 with an elongated process extending 
upward toward the curved inner margin of the hook (Fig. 31); 
Li with a curved, heavily sclerotized cleft, lower lobe lacking 
setae, with an unevenly broad, sclerotized marginal area (Fig. 32). 
Measurements (mm) : Overall length about 21 ; length and width 
of pronotum, 5.6 X 8.6. 
Coloration: Head black. Pronotum brownish yellow, semi-hya- 
line; a broad black inverted Y-shaped band extends from the anterior 
arched border to the disk; a broad black, undulating band extends 
along the posterior border between the two lateral angles. Abdominal 
tergites and sternites piceous. Tegmina reddish tawny, costal area 
testaceous and corciaceous towards base, with a dark humeral line; 
right tegmen with a large blackish region where it is covered by 
the left tegmen. Wings brownish. 
Material examined : Holotype cf of Panchlor a inaequalis Walker, 
locality unknown. From Mr. Argent’s Collection. Type in British 
Museum (Natural History). 
Shelford (1907) stated that Ischnoptera (?) obliqua Walker 
“appears to be undoubtedly referable to the genus Pinaconota, Sauss. ; 
it can be distinguished from the only other species in the genus 
P. bifasciata, Sauss., by its much larger size.” P. obliqua differs 
markedly from bifasciata in femoral armature, relative length of 
cerci, bulging eyes, and cf genital phallomeres. Because of the 
morphological differences, especially in the 3 genital phallomeres, I 
am placing obliqua in a new genus characterized as follows: 
Gurneya n. gen. 3 
Type-species: Ischnoptera (?) obliqua Walker (1869, p. 148) 
(present designation). 
2 Princis (1958) placed inaequalis in Proscratea. The femoral armament 
of a female of Proscratea complanata was as follows: Anterior and posterior 
margins of front femur unarmed except for 1 distal spine on each ; genicular 
spine absent. Both margins of mid femur unarmed; distal spines lacking; 
genicular spine present. Anterior margin of hind femur unarmed; hind 
margin with 3 widely spaced heavy spines; distal spines absent, genicular 
spine present. 
The genus is named in honor of Dr. Ashley Gurney, orthopterist at the 
United States National Museum, who has helped me considerably in my 
taxonomic studies of the Blattaria.
