half the length of body, the ratio being 1 : 2-3-27 (2-5), and slightly shorter than the hind 

 legs, the ratio about 1 : 11. Scape 46-58 (52) u. long and 61-70 (64)0. wide at base ; almost 

 always with 4 and occasionally 5 h.s. (av. 42). Pedicel 58-67 (6i)ji. long and 46-52 (50) u, wide ; 

 with 1-4 (22) f.s., 3-7 (5-5) h.s. and a sensillnm placodeum. Flagellum : Flagellar segments 

 III to IX 37-43^ wide (segments VI, VII and sometimes VIII somewhat wider than the 

 preceding segments) ; segment X 31-34;/ wide. Segment III club-shaped and longest of all, 

 the ratio its length to the length of segment X 1-5-2-0 (i-8) : 1, and its width to its length 

 1 : 1-8-2-3 ( 21 )- Segments IV to IX barrel -shaped, the ratio width to length of segment IX 

 being 1 : 0-9-1-1 (i-o). Terminal segment pear-shaped. Segments VI to X and sometimes V 

 also, with a few apically knobbed capitate sensory setae. The lengths of the flagellar segments 

 and the number of setae on each are given in the following table :

A ntennal bristles well denned ; segments VI 1 1 and IX each with one ventral bristle. Segment 

 X with one dorsal preapical bristle, two lateral ones at a greater distance from the apex and two 

 apical small hair-like setae. 



Thorax : 372-471 (426) y. long. Pronotal ridges medially interrupted at a weakly sclerotized 

 point ; lateral pronotal sclerites and post-tergites small. Proepistermim without any ridge-like 

 sclerotization. Prosternum narrow, 24-34 ( 2 7)|^ long ; prosternal ridge 79-92 (89) u. long. 

 Prothoracic setae almost always absent but one medial pronotal, one lateral pronotal and one 

 anlespiracular dorsal seta were found on each side of one specimen. 



Mcsothorax : Prescutum 43-52 (46) [x long and 122 143 { 1 3 1 ) jjl wide, the ratio being 1 : 2-5- 

 3-2 (2-9) ; prescatal ridge slender and prescutal suture distinct. Scutum 31-55 (49) u. long, i.e. 

 the ratio lengths of prescutum to scutum 1 : 0-7-1-4 (i-i). Prealare, prealar ridge, tegula and 

 triangular plate conspicuously degenerate. Scutellum trapezoid in dorsal view ; 43-61 (55) t*. 

 long and 159-183 (168) u. wide, the ratio being 1 : 2-6-3-7 (3 1 ). anci i ts length to the length of 

 scutum 1-0-1-5 ( I-1 ) : l '• scutoscutellar suture weakly developed and usually partly missing ; 

 scutellar ridge absent. Postalare with the anterior and posterior ridges anteriorly joined. 

 Postnotal apophysis greatly reduced. Mesopleuron : Mesopleural ridge continuous above the 

 coxal articulation, dorsally supporting a small pleural wing process. Basalare extremely weak 

 and slender. Subepisternal ridge atrophied and sometimes absent altogether. Mesepisternum 

 well-defined and mesepimeron small. Later opleurite comparatively large, with a small oval 

 membranous area. Mesosternum : Basisternum 107-131 (ii9)|x long and 177-201 (i86)u. 

 wide ; marginal ridge usually partly absent anteriorly ; precoxal ridge slender and furca greatly 

 reduced. Mesothoracic spiracle 18-24 (21) u- wide at opening, with a 46-52 (49) u. long supporting 

 bar. Mesothoracic setae on each side : Prescatal setae absent ; sculal setae 1-5 (2-9) ; scutellar 

 setae 1-3 (i-8). Tegular setae 0-1 (0-2). Postmesostigmatal and basisternal setae absent. 

 Metathorax : Metapostnotal sclerites narrow ; metapostnotal ridge absent. Metapleural ridge 

 weak, attenuated near the middle as usual, and dorsally reduced. Precoxal ridges absent and 

 metasternal apophysis vestigial. Metathoracic spiracle similar to the mesothoracic. Mela- 

 thoracic setae on each side : Metatergal setae 3-8 (47) and anterior metasternal setae 0-1 (0-9) ; 

 metapleural setae absent and posterior metasternal setae 0-1 (0-3). 



Wings : Greatly reduced ; 126-308 (182) u. long and 42-140 (84)0. wide ; axillary sclerites 

 small ; additional sclerite and alar lobe absent ; one alar seta almost always present and
