CICADELLINAE: PART 2. NEW WORLD CICADELLINI 1053 
2. Male with elongate microsetae occurring mostly on basal half of plates; 
female abdominal sternum VII not keeled and with teeth on apical 
three-fourths of second valvulae of ovipositor 
impressifrons (Signoret) (figs. 851, 852) 
Male with elongate microsetae throughout length of plates; female ab- 
dominal sternum VII keeled and with teeth only on apical one-half of 
Reconmvalenlag@ol OVIpositor!:. 4... 04 ives Gata ye de - crinata, Nn. sp. 
Borogonalia crinata, NEW SPECIES 
FiGuRE 854 
Length of male 4.4-6.3 mm, of female 5.3-6.8 mm. Head with median 
length of crown varying from six-tenths to slightly less than seven-tenths in- 
terocular width and from one-third to four-tenths transocular width. Male 
| plates with numerous elongate microsetae, without macrosetae. Female ab- 
dominal sternum VII keeled medially, with apex of median produced portion 
bearing a shallow median notch which bears a broad convexity; ovipositor 
with second valvula bearing teeth on apical one-half of its dorsal margin. 
- Black markings of crown variable in extent, at most as in the illustration of B. 
impressifrons (Signoret) (fig. 851a), at least with an arcuate anteapical marking 
and a spot on apex; scutellum varying from unmarked to black from anterior 
margin to transverse sulcus, except a pair of pale circles and the lateral 
margins of this area; face unmarked yellow. Other characters as in generic 
_ description. 
Holotype male, Abancay, Peru, July 12, 1960 (Salazar and Young), and a 
series of 55 additional topotypic specimens of both sexes, two collected from 
- Asclepiadaceae (NCS). Eleven specimens, both sexes, from 10 km. south of 
Chiclayo, Peru, March 21, 1951 (Ross and Michelbacher) (CAS). Holotype 
on indefinite loan to USNM. 
B. crinata, n. sp., is very similar to B. impressifrons (Signoret) from which it 
can be separated easily by the characters used in the key. The numerous, 
matted, close-set microsetae are conspicuous in unmacerated specimens, ex- 
tending beyond the apices of the plates, and often concealing the ventral sur- 
face of the plates in dried specimens; in impressifrons the elongate microsetae 
are more nearly restricted to the basal half, and do not extend beyond the 
midlength of the plates, the macrosetae being readily observed in dried speci- 
mens.

Head with median length of crown varying from slightly less than three- 
tenths to slightly less than four-tenths transocular width, ocelli located behind
