I>4»i'.^ iiiyi'iiiex Mayr. ^ . Miiiulibles triangular, external marsi" liroadly 

 curvi'd. apical (or l)itiiii;) marjiin lU'iitale. with a larjii' tooth in front : maxillary 

 pali)i (j-jointi'(l, joints 1 -J very short, '.i very lonjr, curved, thiekened toward apex ; 

 labial palpi 4-,jointed ; (■lyi)fus triaiitrular, slightly projecting between insertion 

 of aiitennip, not carinate, posterior angles rounded ; clyiieal and antennal fovea* 

 confluent; frontal eariuic short, linear, parallel, slightly diverging behind; an- 

 tenniB 12-jointed. inserted at the margin of the clypeus. scape long, slender, 

 funicle filiform, the joints from base to apex of the latter gradually shorter, basal 

 joint very long, tlie penultimate very short; frontal area sul)triangular ; eyes 

 ovate, placed in the superioi- ])art of tlie head nearly equidistant from the ante- 

 rior and posterior margins; ocelli distinct ; occiput deeply arcuately excavate, the 

 lateral margins slightly curved, the head beneath with a circle of long hairs: 

 thorax constricted i)etween meso- and metathorax. the latter arched above, armed 

 with a tooth or obtuse horn : abdomen, seen from above, with four segments, 

 anus inferior, the jx'tiole either with a node or scale; legs slender, spurs of pos- 

 terior tibia' with long pectinations. 



9. — Head oval, convex above, excavated beneath, very broad bciiind the mid- 

 dle; clypeus transversely triangular. ]irojecting between insertion of antennie. 

 convex medially ; frontal area acutely triangular; frontal groove short and dis 

 tinct ; antennfe 12-jointed ; thorax compressed ; metathorax unarmed ; abdomen 

 elongate oval, the scale of the one-jointed petiole erect, ovate, obtusely toothed 

 above; wings witli two submarginal cells; tibial spurs pectinate. 



%. — Mandibles moderately long, apical (or biting) margin multidentate, the 

 apex very acute ; clypeus transversely triangular, projecting slightly between the 

 insertion of antennie; moderately convex; antennse i;5-jointed. the two basal 

 joints of funicle longer than tlie remainder; niesothorax produced above the 

 prothorax ; metathorax unarmed; abdomen oval, the petiole above sul)nodose; 

 It^gs very slender, tibial spurs jiectinate; external genital valves compres.sed, sub- 

 linear, rounded at tip. 



This ijeims, ami also the pi'eceding, beh)no' to tlic F(M-iiiici(he, and 

 afe placed by Dr. Mayr between Prenolepia and LioinrfDjium. 



I>ol><>l>dtA Mayr. — 5. Mandibles flat. de])ressed, slender, triangular or 

 parallel-margined, obliquely truncate at tiji so that the truncation is the "biting 

 edge." which is toothed ; cly|ieus I'levati'd medially, kite shajicd and carinate, 

 the carina extending posteriorly between the closely jilaced frontal ridges; the 

 anterior middle of the clypeus is obtuse or sharjily prolonged and tills uji the 

 triangular space left by the mandibles; antennae 12-ji)inte(l, the scape long, reach- 

 ing beyond the occiput, first joint of llagellum as long or longer than the .second ; 

 eyes moderately large and rounded ; thorax feebly convex above, subcompressed 

 laterally, prothorax much narrowed anteriorly, me.sothorax very short, only one- 

 third as long as the prothorax and indistinctly separated from the metathorax. 

 the face of whi<'li is more or less abruptly declivous; abdomen long, cylindrical, 

 scale of the petiole sometimes compres.sed laterally, longer than broad, or the 

 length and tireadth are subequal. or it is very strongly compressed from before 

 and bi'hind and transverse; tarsal claws pectinate.
