and more projecting wings. The size of the eye and length 

 of forceps agree closely with csau, but the very different type 

 of tegmina and wings may compel generic separation of the 

 present species when more material of this group has been 

 secured. Whereas csau and auriconia have a similar general 

 appearance, the present insect has a decidedly different facies, 

 due largely to the coloration and form of tegmina and wings. 

 The following features are noted for the type. Entire insect buffy; 

 head, median portion of pronotum, exposed surface of wings and 

 abdomen suffused with brown. Forceps tinged with reddish brown. 

 Eyes of moderate . size, as long as cheek. Pronotum appreciably 

 longer than broad, lateral margins very feebly diverging caudad, 

 straight, with a few microscopic bristles and a larger bristle at the 

 latero-cephalic angle. Tegmina elongate, sutural and costal margins 

 parallel, distal margin feebly convex and feebly produced toward 

 costal margin, truncate. Wings extending moderately beyond tegmina 

 a distance nearly equal tegminal width. Forceps short, heavy, about 

 two and three-quarters times proximal width, general form much as 

 in auricoma. Head, pronotum and tegmina moderately well supplied 

 with minute microscopic hairs, exposed surface of wings and abdomen 

 heavily supplied with these, forceps moderately supplied with the same. 



SPARATTINAE. 



Sparatta diplatyoides (Caudell).

It is our opinion that the species is valid. The type female 

 has the forceps and pygidium identical with those of S. biollcyi 

 Borelli, 4 except that the forceps are proportionately shorter 

 a.nd these organs in diplatyoides are proportionate to its much 

 smaller size ; length of body, exclusive of forceps, 7.5 ; of for- 

 ceps, 2 mm. 



The original description is good. The pygidium was not 

 described ; it is quadrate, with lateral margins very feebly con- 

 cave to the very finely pointed latero-caudal angles, between 

 which the caudal margin is transverse, showing a weak con- 

 vexity mesad. 



R This species has been synonymized with a query by Burr in the 

 Genera Inscctonim. under Sparatta pckimctra Serville, described from 

 Brazil. 



1 Material of both sexes of that species from Costa Rica is at 

 hand.
