with all the joints cylindrical, the basal flagellar joint elongate and 

 the six central, like the scape beneath, stramineous. Thorax not 

 very slender, entirely dull, closely and finely punctate throughout ; 

 black, with prothorax basally throughout, hamate marks on either 

 side of front of mesonotum, callosities before and beneath radices, 

 and a mesopleural mark before the intermediate coxa3, strami- 

 neous ; notauli wanting ; metathorax white-pilose, with no trace 

 of costae, the lateral cnrinse extremely obsolete, the spiracles small 

 and circular. Seutdlum stramineous, sparsely punctate but dull; 

 postscutellum black. Abdomen hardly longer than thorax, dis- 

 tinctly punctate, more obsoletely and shining towards the com- 

 pressed anus ; basal segment hardly twice as long as apically 

 broad, constricted before its di- 

 lated and broadly stramineous 

 base ; apical margins of the three 

 basal, of the sixth and following 

 segments, broadly flavous ; tere- 

 bra somewhat stout, straight and 

 not longer than the two basal 

 segments. Legs fulvous, with the 

 front or anterior coxa? and tro- 

 chanters stramineous ; hind legs 

 elongate, with apices of coxae, 

 femora, tibiae and tarsi, together 

 with base of the last, black ; hind 

 tarsi mainly, and base of their 

 tibiae, whitish ; all the tarsal 

 claws sparsely and obsoletely 

 pectinate. Wings entirely hya- 

 line, radix and tegulae stramineous, costa and stigma piceous ; 

 areolet subsessile, irregular, emitting the inner cubital from near 

 its centre and the recurrent from its apical third ; radinl nervure 

 straight ; nervellus subpellucid, emitted far below centre of the 

 straight and slightly postfurcal first recurrent of lower wings. 

 Length 8 millim.

Type in the British Museum. 



This species probably merits generic rank in the modern too 

 elaborate classification, since it differs from Lissonota (sensu strido) 

 in its lack of metapleural carinaB, though sufficiently closely re- 

 lated in its sparsely pectinate claws and circular metathoracic 

 spiracles, which will distinguish this brightly marked species from 

 the similarly decorated ones of Syzeuctus. 



Described from two females in the British Museum.
