Mock ford — Electrentomoid Psocids 
125 
Records. — Mexico: Veracruz: about io miles east of Orizaba 
on Highway 150. 
Habitat. — At both localities, this species was found in dried 
banana leaves hanging from the tree. 
Musapsocus creole, new species 
Diagnosis. — Vein 2A in forewing ending freely, joining neither 
iA nor wing margin. Male with continuous band of papillae across 
dorsum of clunium. Male with parameres joined anteriorly to form 
short slender rod. Female third ovipositor valvula with slight indi- 
cation of bilobing at apex. Female subgenital plate with posterior 
margin in form of flat arc; plate bearing small T-shaped sclerite 
without arms. 
Male. — Measurements (Table I). 
Morphology. — Lacinial tip (fig. 3) with median cusp simple. 
Hypandrium with posterior margin thickened and slightly bilobed. 
Phallosome (fig. 4) : parameres showing basal line of fusion; pos- 
terior branching of parameres resulting in pair of converging arms 
curving posteriorly before meeting and having broad, truncated ends 
with tiny denticles on lateral margins; lateral branches of parameres 
curved out then in, apparently rebranching near tips. Clunium dor- 
sally with transverse field of small denticles in anterior half, and 
transverse region of larger denticles (fig. 15) in posterior half. 
Paraproctal sensorium with 10 trichobothria and 3 setae without 
basal rosettes. 
Color (in alcohol). — Body and appendages generally dull ivory 
yellow. Compound eyes black. Reddish brown pigment distributed 
as follows: a small circle ventro-mesal to each antennal base; diffuse 
granules above subgenal suture and concentrated around anterior 
mandibular articulation, a lateral stripe running entire length of 
thorax, a band across anterior border of mesonotal lobes, irregular 
lateral blotches on base of abdomen, a band across abdominal dorsum 
in region of fourth segment, a spot around each antero-lateral angle of 
clunium, granules irregularly distributed in epiproct and paraprocts. 
Female. — Measurements (Table I). 
Morphology. — Subgenital plate (fig. 22) with posterior margin 
slightly curved and beset with 9 stout setae. T-shaped sclerite 
present in form of rod with slightly thickened base. Partially cleft 
interior plate clearly seen through subgenital plate in preparation. 
Ovipositor valvulae (fig. 16) : first valvula lacking basal appendage; 
third valvula slightly bilobed at apex. Spermatheca with sac dis-
