light cress-green, on the tegmina and exposed portions of the wings. 

 The original color was probably more green than is now the case 

 with the type specimen, but to what extent we cannot say, and the 

 coloration described is that found in the present condition of the 

 individual. Eyes cinnamon-brown, blotched with fuscous. An- 

 tennae, except for the proximal portion which is of the general color, 

 clear kildare-green. Femora of the general color, tibiae weakly 

 light cress-green. 



Length of body, 21.8 mm.; length of pronotal disk, 5.3; greatest 

 (caudal) width of pronotal disk, 3; length of tegmen, 29.3; greatest 

 width of tegmen, 6.1; length of caudal femur, 19.8. 



The type of this most interesting species is unique. 



Anaulacomera libidinosa new species. (Plate X, figs. 24; PI. XI, fig. 25.) 



Apparently close to A. chelata Brunner, ha\Ting wdth the older 

 species a unique position in the genus by possessing an articulate 

 appendage attached to the cercus of the male, but differing from 

 chelata in the lateral lobes of the pronotum being longer than high, 

 and in the articulate arm of the cercus being of a more highly special- 

 ized, character, having the apex of the same blunt and depressed and 

 the ventral surface with an arcuate compresso-lamellate expansion. 

 Type. — cf ; Bonito, State of Pernambuco, Brazil. January 16, 

 1883. (A. Koebele.) [United States National Museum.] 



Size medium: form distinctly compressed, deep: surface of limbs 

 shining, of most of body dull. Head slightly broader across genae 

 than caudad of the eyes; face faintly bullate, slightly compressed 

 and the infra-antennal region impressed: palpi elongate, slender: 

 -eyes moderately prominent, faintly flattened subglobose when seen 

 from the dorsum, slightly projecting cephalad, basal outline sub- 

 circular: antennae slender, proximal joint relatively large. Pro- 

 notum with the disk narrow, its greatest caudal width contained 

 about one and two-thirds times in the greatest length of the same, 

 surface of the disk faintly arcuate transversely cephalad, deplanate 

 caudad, lateral angles moderately indicated caudad, more rounded 

 cephalad, surface of the disk with a fine medio-longitudinal sulcation, 

 across which, shghtly caudad of the middle of the disk, is placed an 

 obtusely-angulate sulcation, which does not reach the lateral angles 

 of the disk; surface of the cephahc portion of the disk slightly riigu- 

 lose: cephalic margin of the disk truncate, caudal margin of the disk 

 moderately arcuate : lateral lobes of the pronotum slightly longer 

 than deep, nearly vertical; cephahc margin arcuato-emarginate,
