306 ME. W. r. KIEBY— A EEVISION OF 



very small, sectors of the triangle widely separated : anal appendages of the male not 

 much curved, a little longer than the eighth segment, the lower appendage hardly 

 shorter than the others; appendages of the second segment not conspicuous. 



Type Cannaphila insularis, sp. n. 



The above characters are partly based upon a male from Jamaica, and a female from 

 Guatemala, undoubtedly congeneric with C. insularis, but not in sufficiently good 

 condition to describe. 



Genus 72. Cacergates, g. n. 



Frontal tubercle rather broad, a little depressed in the middle ; eyes contiguous in 

 front ; abdomen moderately stout, considerably thickened at the base, shorter than the 

 hind wings, segments 2-4 carinated, segment 8 not perfoliate in female : wings rather 

 short, pterostigma moderately long, pale or particoloured ; fore wings with 8-9 ante- 

 nodal nervures, the last not continuous, and 6-8 postnodals, the first three or four not 

 continuous, cells of the postnodal area simple, triangle moderate, free, on a level with 

 that of the hind wings, the base straight, followed by three rows of cells, increasing, 

 no supratriano-ular nervures, one cross nervure in the lower basal cell, subtriangular 

 space consisting of one cell, sectors of the arculus stalked, gradually curved, nodal 

 sector only slightly waved at the base, the subnodal nearly straight, the intermediate 

 cells only bisected close to the hind margin ; hind wings broader than the fore wings, 

 with 6-7 antenodal and 7-8 postnodal nervures, the first two or three postnodals not 

 continuous, triangle free, its base nearly coinciding with the arculus, and followed by 

 three rows of cells, increasing, no supratriangular nervures, one cross nervure in the 

 lower basal cell, sectors of the triangle widely separated at their origin : anal appen- 

 dages of the male as long as the last two segments, considerably depressed, the lower 

 one shorter than the others ; appendages of the second segment not conspicuous. 



Type Libellula leucosticta, Burm. 



Genus 73. Calothemis. 

 Selys, ]\Iitth. Mus. Dresd. iii. p. 305 (1878). 



Differs from Orchithemis as follows : — Abdomen considerably shorter than the hind 

 wings, broader than in Orchithemis, and very slightly tapering, especially in the male, 

 eighth segment perfoliate in female : fore wings with the nodal sector more waved and 

 the cells between the nodal and subnodal sectors bisected towards the hind margin, 

 triangle traversed, preceded by one or two supratriangular nervures, two to five cross 

 nervures in the lower basal cell, subtriangular space consisting of three cells ; hind 

 wings distinctly broader than the fore wings, triangle traversed, followed by three rows 

 of cells, one or two supratriangular nervures, two or three nervures in the lower basal 

 cell: anal appendages of male as long as the eighth segment, or a little shorter, those 

 of the second segment much less conspicuous than in Orchithemis. 



Type Calothemis meyeri, Selys.
