l)ut only very sliort and inconspicuous pubescence. The 

 seventh ventral segment has the lateral wings ample, and 

 they are strongly acutely produced at their apical angle, and 

 bear and are ciliated with a peculiar short pubescence ; at 

 the apex of the segment in the middle between the wings 

 arise, side by side, two small, hairy, elongate processes. 

 The eighth segment is prolonged into a strong and very 

 elongate chitinous process, widest at about the middle, with 

 a dense and peculiar pubescence on its apical half. 



Euryglossa variabilis, sp. n. 



Very variable in colour, black, the abdominal pleura for 

 a large part white : or (a) black, the fourth and fifth abdo- 

 minal segments brightly ferruginous ; or (/3) black, the whole 

 abdomen, except the extreme base, ferruginous ; or (7) black, 

 the whole mesouotum and scutellum ferruginous, the 

 abdomen black ; or (h) head black, mesouotum and scutel- 

 lum ferruginous, abdomen, except extreme base and the fifth 

 and sixth segments, ferruginous. Intermediate conditions 

 also occur — e. g., the apical margins of the second and third 

 segments narrowly, the fourth very widely, and the whole 

 of the fifth may be ferruginous. When the abdomen is 

 black, this has a greenish lustre, but in the red-bodied 

 specimens it disappears, and on the red parts in inter- 

 mediates. The pleura remain largely white in all varieties. 

 The legs also vary in the brightest forms, the tibioe and 

 tarsi being sometimes clear testaceous ; in dark varieties 

 they may be black or pitchy. 



Mandibles more or less red, the face at the sides densely 

 clothed with white hairs. Clypeus shining, densely and 

 finely punctured at the sides, plentifully, but more coarsely 

 and irregularly, in the middle ; f rons dull and very densely 

 punctured. Mesonotum very smooth and shining in the 

 middle, where it is strongly and remotely punctured, but 

 very densely in front and at the sides in front of the tcguhe ; 

 scutellum shining, coarsely punctured in front, densely and 

 more finely along the hind margin ; postscutcllum dull and 

 very densely and roughly, finely punctate. Anterior area of 

 propodeum smooth and shining, with microscopic surface- 

 sculpture most noticeable in front and behind, rest of pro- 

 podeum with white pubescence. Abdomen ovate, dull, with 

 excessively dense microscopic surface-sculpture, not or 

 hardly punctured ; basal segment with short hairs basally, 

 second, third, and fourth nearly bare or only with very short 

 incons])ieuous hairs, fifth with longer suberect hairs and an
