 back of each eye on the vertex and continued back on the anterior part (only) 

 of the pronotum. Wings with very broad costal area, apex hardly acute, 

 gradates black and margined, six in inner series, eight in outer row, inner 

 series irregular, but nearer to radial sector than to the outer series, the margi- 

 nal forks three times as long as broad, all veins rather stout, many faintly 

 obscured, costals black at ends or almost wholly black, about 20 before 

 stigma, three or four beyond end of the subcosta, radial cross-veins dark at 

 upper end, divisory veinlet ends much beyond the cross-veins, second cubital 

 cell as long as third, base of third oblique; pronotum but little longer than 

 broad, narrowed in front. 

 Expanse, 29mm. 



From Bartica, British Guiana, December (Parish). 



Chrysopa albatala n. sp. 



Runs to C. atala Br. in Navas table, and very near to it, but differs at once 

 in lacking a dark mark on cheeks and the palpi are marked with black. 

 Antennae pale, basal joint with a dark line on outside; pronotum as broad as 

 long, barely broader behind. Wings rather short, hardly acute at tips, with 

 but few veins, about sixteen costals before stigma, four cross-veins behind 

 stigma; gradates with four inner series and six in outer series, inner series 

 nearer to the outer than to the radial sector; marginal forks about twice as 

 long as broad; divisory vein ends at or a little beyond the cross-vein; third 

 cubital equal to second, latter narrowed at tip and the third at base, more 

 than usual. 

 Expanse 21 to 23 mm.

Leucochrysa nigrovaria Walker. 



Pale yellowish, a broad dark brown band under base of antennae from 

 eye to eye, the lobe of vertex with a curved dark line in front; palpi un- 

 marked; antennae pale, first joint with an oblique, rather broad dark brown 

 stripe above, second joint dark brown, next four or five joints infuscated 

 within; margin of pronotum narrowly dark, a black spot on each lateral lobe 

 of the mesothorax, and another near base of the fore wing, metathorax with 

 dark spot above base of hind wings, third and fifth abdominal segments 

 marked with black. Prothorax narrowed in front, a little broader than long. 

 Wings with green venation; origin of radial sector, base of the divisory vein- 

 ,let, outer gradates, ends of radial cross-veins and a few others dark; in hind 

 wings venation almost wholly green. Stigma in both pairs dark in base. 

 Seven or eight gradates in each series, inner series not nearer outer than to 

 radial sector; marginal forks three times as long as broad; 21 costals before 

 stigma in -the fore wing. 

 Expanse 35 mm.
