Graphocephala penignava, NEW SPECIES 
FIGURE 696, PAGE 863 
Length of male 5.4 mm, of female 5.6-5.7 mm. Head moderately produced, 
median length of crown varying from seven-tenths to almost nine-tenths in- 
terocular width, and from slightly more than four-tenths to slightly more than 
seven-tenths transocular width, ocelli located on a line between anterior eye 
angles, each approximately equidistant from adjacent anterior eye angle, and 
median line of crown, surface with shallow elongate inconspicuous punctures; 
antennal ledges with anterior margins slightly oblique and usually rectilinear 
in lateral view, face without a lenticular sclerite bordering lateral clypeal 
suture on each side below eye, clypeus with muscle impressions not very dis- 
tinct. Thorax with pronotal width equal to transocular width of head, 
pronotal margins convergent anteriorly, disk very weakly transversely 
rugulose; scutellum not or inconspicuously rugose behind transverse sulcus; 
forewing with veins distinct in clavus and in region of anteapical and apical 
cells, outer anteapical cell usually not containing supernumerary crossveins, 
which may extend however from outer margin of this cell to costal margin (in 
one specimen the crossveins involve the entire outer anteapical cell, as in G. 
versuta (Say)), hindleg with length of first tarsomere approximately equal to 
combined length of two more distal tarsomeres. Male pygofer well produced, 
with a slender, acute process arising near middle of dorsal margin, extending 
ventrally, apical margin broadly convex; plates extending posteriorly as far as 
pygofer apex, each with uniseriate macrosetae; style extending posteriorly 
approximately as far as apex of connective; aedeagal shaft short, without pro- 
cesses, dorsal apodemes conspicuous; paraphyses consisting of a basis and two 
rami of which the more anterior one is slightly shorter, both extending dor- 
sally in lateral view. Female abdominal sternum VII strongly produced and 
narrowly rounded apically; ovipositor with primary teeth of second valvulae 
widely separated, acute apically; pygofer with setae almost all anteapical. 
Color of crown yellow, with an apical black spot, with a linear arcuate 
black marking extending from dorsal portion of lateral clypeal suture towards 
apex on each side, occasionally confluent medially with its complement, with 
a pair of slender median longitudinal dark lines on posterior two-thirds of 
disk, delimiting a paler median line which is interrupted anteriorly by a me- 
dian black spot, the paired median dark lines occasionally each curved 
posterolaterally at their anterior extremities; pronotum pale green anteriorly 
and laterally, remainder dark green; scutellum yellow with transverse sulcus 
and a pair of short marks on posterior half, black, most specimens with 
variable additional black scutellar markings; forewing dark green, basal one- 
half or more of costa and apical one-fourth of claval commissure narrowly 
dull-yellow, without a black spot in apex of any of apical cells; face with small 
brown and black variable markings; thoracic pleura dull yellow marked with 
black, legs and venter of abdomen dull yellow, apices of tarsi of first and 
second legs dark. 
Holotype male and six additional males, Mexico City, D. F., September 13, 
1939, eleven females, same data (DeLong collection, OSU).
