long. Median segment with a smooth, shining triangular space 

 at the base ; from the apex of the triangle a deep sulcus runs to the 

 apex of the segment, the remainder of the segment shining, with 

 microscopic punctures. Abdomen oval, as long as the thorax and 

 median segment combined ; the first segment narrow at the base, 

 no longer than the second segment which is very broad ; all the 

 segments finely and very closely punctured ; the pygidium elon- 

 gate-triangular, with sparse, short pubescence. 



Black ; the mandibles at the base, clypeus, scape of the an- 

 tennae, pronotum, tegulae, a spot on the mesopleurte beneath the 

 anterior wings, a short transverse line at the apex of the scutellum, 

 the postscutellum, a large spot on each side of the second abdo- 

 minal segment, a transverse band very narrowly interrupted in 

 the middle at the apex of the fourth segment, the apex of the 

 anterior femora, and a line on all the tibi?e above, pale yellow ; 

 the flagellum, the apex of the mandibles, the legs, the first 

 abdominal segment (except at the base), and the two apical 

 segments ferruginous. 



The first recurrent nervure is received near the apex of the 

 first cubital cell, the second close to the apex of the second. The 

 first cubital cell is longer on the cubital nervure than the second 

 and third combined ; the second as long as the third, but much 

 shorter on the radial nervure. 



Length 7 mm. 



Ilab. Australia, IST.W. Coast [Du Boulay). 



Type in British Museum. 



This and the two following species form a gi-oup of allied forms 

 approaching the subgenus Miscothyris Sm., from which they may 

 be distinguished by the shorter and more oval abdomen and the 

 very large and broad second abdominal segment. 



GoRYTES SAXGUiNOLENTUS, sp. n. (Plate XXYI. fig. 10.) 



5 . Clypeus broad, slightly convex, about two and a half times 

 as broad on the apical margin as long, truncate at the apex, the 

 labrum slightly prominent ;, minutely punctured. Eyes large, 

 strongly divergent towards the clypeus and towards the vertex, 

 separated on the front by a distance rather less than one and 

 a half times the length of the scape. The posterior ocelli twice 

 as far from each other as from the eyes, separated from the eyes 

 by a distance about equal to the length of the third joint of the 

 flagellum. Antennae inserted on the front, above the base of 

 the clypeus, about equal in length to the head, nearer to the eyes 

 than to each other ; the scape as long as the first three joints of 

 the flagellum combined ; the second joint of the flagellum longei' 

 than the third, the apical joints thickened. Head opaque, very 

 minutely punctured, veitex flattened. Pronotujn linear and 

 transverse, nearly two-thirds of the breadth of the head; meso- 

 notum more than half as broad again as long, fiiiely punctured ; 

 scutellum large and broad, truncate at the apex. Median 

 segment of about the same length as the scutellum, rounded
