TRIOZA PROXIMATA Crawford. 



Figs. 388, 529. 



Trioza prorimata Crawford '11a: 435. 



Length of body (female) 3.4 mm; (male) 2.4; length of forewing 

 3.7; width of head 0.78. General color light greenish yellow; ovi- 

 positor of female black; antennae black apically. 



Head small, much narrower than thorax; vertex a little more than 

 half as long as broad, somewhat bulging in front on each side of 

 median line, with a deep foveal impression posteriorly on each side; 

 genal cones short, half as long as vertex, only slightly divergent, 

 subacute, pubescent. Antennae about twice as long as width of head. 



Thorax large, broad, strongly arched, punctate; pronotum rather 

 short, strongly descending cephalad; propleurites broad. Prsescutum 

 very narrowly rounded cephalad. Mesonotum long. Hind tibisB 

 with three apical spines within. Wings about two and a half times 

 as long as broad, broadly rounded at apex; Rs very olong. 



Genitalia. — Male. — Genital segment large. Anal valve about as 

 long as forceps, triangular in outline, posterior margin angulately 

 arcuate, anus on an epiphysis; forceps long, curved cephalad, and 

 arcuate toward each other, rather slender, acutely pointed at apex, 

 with two ridges of hairs on inner surface. Penis long. Female. — 

 Genital segment very elongate and styliform except at base, nearly 

 three-fourths as long as rest of body; base large, subglobose; apical 

 two-thirds styliform, very slender and acuminate, dorsal valve longer 

 than ventral. Pubescence short. 



Described from several males and females from Oaxaca and Orizaba, 

 Mexico (Crawford), August, 1910. No host plant data. 



Type ill author's collection. 



TRIOZA COLLARIS Crawford. 



Figs. 185, 187, 350, 509. 



Trioza collaris Crawford '10b:347; '11 a: 436.— Patch '12b:225. 



Length of body (female) 2.5 mm; length of forewing 3.7; width of 

 head 0.72. General color greenish yellow; notum more or less 

 streaked with brown; abdomen darker dorsad. 



Very similar in most respects to proximata, differing as follows: 

 Antennae only about one and a half times as long as width of head; 

 praescutum more broadly rounded cephalad; wings less broadly 

 rounded at apex, sometimes subacute. Female genital segment 

 not over half as long as rest of body, usually less than half; styliform 

 prolongation not, or only a little, longer than basal portion. Male 

 genitalia similar, but anal valve roundly arcuate behind, not angu- 

 lately; forceps similar.
