hardly two-thirds of marginal area. I believe that yuca- 
tanensis and divergens are synonyms. 
Chrysopa tortolana sp. nov. 
Face pale, no cheek mark, bnt a dark spot below each 
basal joint close to the socket, some irregular dark spots 
on basal joint and four to six joints beyond black (ex- 
cept second joint), beyond this some joints dark on one 
side; palpi pale; vertex and basal joints above faintly 
pink. 
Pronotum with a narrow red line on each side of front 
part, and a shorter red line on posterior part, much more 
than its width from lateral margin, rest of thorax very 
pale yellow. Venation green; gradates black, several of 
the longer radials dark near upper end, but not at end; 
some of the longer costals marked the same. 
Basal joint of antennae very short and small; prono- 
tum a little broader than long in middle, sides nearly 
parallel. Wings rather broad; costal and medial areas 
both very broad at widest part, but the costal plainly the 
broader; eighteen costals, none sinuous; marginal area 
much broader than cubital, in fact almost twice as broad 
beyond the third cubital cell ; third cubital cell as long as 
and broader than the second ; divisory cell about twice as 
long as broad; six cubitals beyond; medius ends far be- 
fore tip, full five forks before the tip. 
In fore-wing six inner and seven outer gradates, each 
gradate well separated from next ; rows not parallel, the 
inner as near radial sector or nearer toward end than to 
the outer row; in bind wing four inner, six outer gra- 
dates, inner nearer to radial sector for most of length; 
in bind wings all veins green. 
Length of fore-wing 14 mm., width 4 mm. 
One from Vergel, Chiapas, 4 June, at light. 
Type: M.C.Z. no. 27998. 
This species resembles Ch. tetrasticta , but the anten- 
nae are black for a short distance and partly black for a 
greater distance, also the black on face, and the cross- 
veins not clouded separate it; the red marks on prono- 
tum are more slender than in tetrasticta.
