and including scutellar apex, truncate on each wing at claval suture, and a 
second similar band at claval apex, but crossing claval suture and attaining 
costal margin or not, with a smaller round yellow spot including outer an- 
teapical cell and base of outer apical cell, with or without a yellow stripe 
parallel to costal margin in middle portion of length ‘of latter; face, thoracic 
pleura, and legs, pale yellow, except for a black marking below lateral 
pronotal carina in some specimens. 
Holotype male and one female, Guasca-Gacheta, Puente Licio, Cun- 
dinamarca, Colombia, February 20, 1942 (Chapin No. 658); one male, Ouro 
Preto, Brazil, April 1954 (N. L. H. Krauss) (USNM). One female, 3 mi. west 
of Villavicencio, Meta, Colombia, 920 m., March 11, 1935 (E. I. Schlinger 
and E. S. Ross) (CAS). One male, Bogota, Colombia (L. Richter); one 
female, Colombia (L. Richter) (NCS). One female, Rio de Janeiro (MMB). 
This species is named in honor of the late Dr. E. A. Chapin, a respected 
colleague and a good friend. 7. chapini, n. sp., is closely related to scalarum and 
vargasi, n. sp. (below). It is easily distinguished from scalarum by the longer 
male plates and by the form of the female abdominal sternum VII which has 
no small protuberance on each side of middle of the posterior margin. The 
ventral margin of the aedeagus is more strongly concave in chafim than in 
vargast.

FIGURE 386, PAGE 469 
Length of male 6.0-6.1 mm, of female 6.4-6.7 mm. Head with median 
length of crown approximately three-fourths interocular width and slightly 
less than one-half transocular width, ocelli located slightly behind a line be- 
tween anterior eye angles, each equidistant from adjacent anterior eye angle 
and median line of crown, other head characters as in 7. chapini, n. sp. 
(above). Thorax as in chapini except that posterior portion of scutellum is 
weakly transversely striate in one specimen. Male genitalia as in chapini, 
except that setae are not as extensive on pygofer and more restricted to 
marginal area, and except that aedeagal shaft is much less strongly concave 
on its ventral margin in lateral view. 
Color of dorsum as in chapini, but with transverse band at claval apex short- 
er, not attaining costal margin in any of specimens at hand, and without an- 
teapical yellow spot, without a pale stripe parallel to costal margin; thoracic 
pleura partly black, mesosternum black, face, remainder of thorax, and legs, 
yellow.
