118 Psyche [August 



the antenna is folded back against the head. Eyes small, situated behind the mid- 

 dle of the head. Ocelli absent. Antennae 12-jointed, funiculus somewhat en- 

 larged at the tip into a 3-jointed club, which, however, is not very sharply marked 

 off from the more basal joints. Palpi extremely short. The number of their joints 

 could not be ascertained. Thorax small and short, with a very distinct promesono- 

 tal but no mesoepinotal suture; epinotum unarmed. Petiole nodiform, attached 

 to the postpetiole by a very small, narrow surface. Postpetiole voluminous, larger 

 than the first gastric segment, constricted behind, remaining gastric segments very 

 small, almost completely telescoped into the first segment. Sting well-developed. 

 Legs rather stout and short; hind tibije each with a single large, richly pectinated 

 spur; tarsal claws simple, slender and straight. Sculpture and pilosity rather 

 coarse. 



Female. Ergatoid and differing from the worker onlj' in having an anterior 

 ocellus and in the larger size of the postpetiole and first gastric segment, and in the 

 latter being as large as the former. 



Paranomopone relicta sp. nov. 



Worlier. (Figs. 1-4). Length 4-4.5 mm. 



Head, excluding the mandibles, scarcely longer than broad, distinctly narrower 

 in front than behind, with broadly and rather deeply excised posterior border and 

 prominent posterior corners, its sides rather straight, its upper surface convex, the 

 gula flattened. Mandibles with slightly convex external borders and about 7-8 

 subequal teeth on the apical borders. Clypeus flat, with a sharp median carina, 

 anteriorly very slightly projecting as a short lobe with straight median border and 

 rounded corners. Antennal scapes about three-fourths the length of the head; 

 first funicular joint about as long as broad: joints 2-8 decidedly broader than 

 long; first and second joints of club subequal, each about as long as broad and 

 together distinctly shorter than the terminal joint. Thorax narrower than the 

 head, broadest through the pronotum, which, seen from above and excluding the 

 neck, is nearly twice as broad as long, broadest in front, with the humeral and infe- 

 rior angles sharp and pointed. Promesonotal suture very sharp and distinct; mes- 

 oepinotum from above less than twice as long as broad, its sides feebly concave, in 

 profile scarcely longer than high, with the base of the epinotum convex and some- 

 what longer than the declivity, which is concave and sloping and has a distinctly 

 crenulate margin on each side. Petiole from above broadly elliptical, slightly 

 broader than long, with rounded sides; in profile as high as the thorax, about one 

 and three-fourths times as high as long, with straight and perpendicular anterior, 

 convex and horizontal superior and concave and perpendicular posterior surface. 

 Ventral surface with a small tooth near its anterior border. Postpetiole from above 

 and from the side rounded, as broad as long, broader and longer than the first gas- 

 tric segment, which is rather cylindrical and encloses the small remaining gastric 

 sements. There is a small blunt tooth at the anterio-ventral margin of the post- 

 petiole. 



Rather shining; mandibles smooth, sparsely and rather coarsely punctate. Cly- 

 peus with a few sharp longitudinal rugae on the sides. Head between the frontal 

 carlnae and medial borders of the scrobes traversed by about seven sharp longitu-
