rows between and parallel to A s and the anal angle. 2 cells between 

 the hind angle of the triangle and the point of origin of A.,, 1 cell 

 between the hind angle of the triangle and A 2 immediately opposite 

 that angle. Superior appendages not acute at . the extreme tip, with 

 an inferior tooth at three-fourths' length.

Gynothemis 36 gen nov. 



Falling in the synopsis of Mexican and Central American genera 

 of Libellulinae (in Biol. Centr.-Amer. Neurop. p. 202), under the 

 same rubric as Faltothemis, but differing therefrom as follows : area 

 between the anal angle of the hind wings and A 3 with the cells not 

 arranged as described for Faltothemis, nor in rows parallel to the anal 

 angle or to A 3 , but more irregularly ; only one row of cells between 

 R. and the supplementary sector next below, M 2 not waved ; front wings 

 with the discoidal triangle free and two posttriangular rows from trian- 

 gle to wing-margin ; femora in both sexes armed with the usual two 

 rows of spines as in most Libellulinae, those of the male not differen- 

 tiated as they are in Macrothemis, Brechmorhoga, etc. 



Type : Gynothemis ve7iipnnctata sp. nov. 



201. Gynothemis venipunctata sp. nov. 



(Plate IX, fig. 146.) 



Wings ochraceous at base, on the front pair for their entire width 

 out to the distal angle of the triangle, on the hind pair from the an- 

 terior margin to within two cells of the hind margin and out to two 

 or three cells distad of the triangle. Antenodals in the subcostal spaces 

 and the cubito anal cross-vein on all the wings, and the angles of the 

 triangle and a few cross-veins distal to the triangle on the hind wings, 

 dotted with brown. 



cT. Frons anteriorly and superiorly (but not laterally) and the ver- 

 tex dark metallic-blue ; lips mostly blackish ; thorax dark brown, sides 

 paler, obscure ; abdomen pale yellowish, a mid-dorsal and a lateral 

 brown or black longitudinal stripe, the laterals beginning at the hind 

 end of segment 3. 



36 This proposed name refers to the fact that the genus, although similar in many 

 ways to Macrothemis, differs, among others, in that the male femora are armed like 

 those of female Macrothemis.
