genitalia in both sexes. Not previously reported from Mexico, it 
now appears to be a tropical species, Arizona representing the prob- 
able northern range boundary. L. negata (Navas) 1913: 316 is very 
similar, but the gonarcus hood is much more developed, extending 
almost to cover the mediuncus viewed dorsally; apical process of 
ninth sternite separated by a distinct v-cleft and with larger teeth, 
pronotum and head more lightly marked. I suspect that when more 
material is available, it will prove to be a geographic or develop- 
mental variant of L. arizonica. This species was described from 
“Guatemala: Amula, Guerrero, 6000 ft, Aug., H. H. Smith.” The 
only Guerrero listed for Guatemala is at 15°29'N, 88°35'W, at an 
altitude of less than 2000 ft. It seems probable that L. negata is 
from Guerrero, Mexico, which is much closer to localities for L. 
arizonica. 
The holotype of L. singulars Navas 1913: 316 was collected si- 
multaneously with that of L. negata; both are identical but for the 
structure of the intramedian cell, the specimen with a quadrangular 
cell being named Allochrysa [now Leucochrysa ] negata, and the 
other, with a triangular cell, Leucochrysa [now Nodita] singularis 
(New synonymy; L. negata has precedence). Navas’ overlooking 
the identity of these two species, while describing them one after 
another, seems quite in character. 
Leucochrysa insularis (Walker) 
Figures 10-16 
Chrysopa insularis Walker 1853: 269. Holotype: “Jamaica/ insularis”, male, British 
Museum (Natural History) (examined). Protochrysopa insularis Kolbe 1888: 74. 
Chrysopa virginica Fitch 1856: 91. New synonymy. Holotype (not seen, probably 
lost): Cartersville, Va. Comparison of a male from Virginia with the holotype 
of L. insularis revealed no significant differences. Nothochrysa virginica, Banks 
1895: 315. Allochrysa virginica, Banks 1903: 143, Bickley and MacLeod 1956: 
184. Nothochrysa phantasma MacGillivray 1894: 170. Six cotypes are present 
in the MCZ, a male from “West Chop Mass., Aug. 8, 1893, MCZ Type 10479” 
is designated lectotype. Banks 1895: 315. 
Leucochrysa cerverai Navas 1923: 325. New synonymy. Type not found. A long 
series from the type locality, Santiago de las Vegas, Habana, Cuba, F. Z. Cer- 
vera, Navas det., is in the MCZ and there is no doubt as to the identity of this 
species. The synonymy with L. insularis was suggested by Alayo 1968: 57. 
Leucochrysa joannisi Navas 1925: 13, “Santiago de las Vegas, Cuba, July 17, 
Aug. 20, 1924, F. Cervera”. No type specimen designated, and no type found 
in the Navas collection, 1974. Alayo 1968: 57 (synonymy). There seems to have 
been no formal description published of this species; it is the color variant of
