Our species are in a very unsatisfactory state, but the paucity of 

 our present material does not enable us to remedy it. Miss Mitchell 

 has given a table of the species identified from the United States and 

 Dr. Grabham figures the two Jamaican species. We have another 

 from Mr. Urich in Trinidad and the junior author collected one in 

 Mexico. The following table, as compiled, appears to show that the 

 continental forms identified as socialis and lowii are not conspecific 

 with the insular forms, and we have no recourse but to rename them, 

 although we would much prefer to have good material for actual com- 

 parison. 



Table 0} species. 



1. Antenna? without spines; longest terminal seta as long as antenna 



geometrica 

 Antenna- with scattered spines; longest terminal seta shorter than antenna 



2. Terminal seta- three, the short one obsolete ?> 



Terminal seta' four 4 



3. Shaft rather numerously spined; terminal digit simple lowii 



Shaft with but two spines; terminal digit double coatzacoalcos 



4. Antenna? with the hair beyond the basal third continentalis 



Antenna? with the hair at about the basal third ,S 



5. Pedicellate digit double, the two forks about equal in length 6 



This digit large and single, the second digit small and arising below the 



apex of the pedicel sapphirina 



6. Shortest spine a lanceolate blade; apical tooth of labial plate broad and 



flat socialis 



.Shortest spine slender, filiform; apical tooth of labial plate triangularly 

 pointed coquilletti

 Uranotcenia lowii Grabham, Can. ent., xxxvii, 401, 1905. 



Described from Santa Lucia. We accept Dr. Grabham's definition 

 of Jamaican specimens rather than Mr. Coquillett's determination of 

 those from Louisiana. 



Uranotaenia coatzacoalcos, new species. 



The antennae are stout with a single stout hair at basal third and 

 two short spines on the other side; at tip two long hairs, not as long
