and a narrow band on the base of the middle tibiae and the calcaria rufo- 

 testaceous. Wings hyaline, the apex smoky from the apex of the stigma ; costa 

 and stigma black, the middle nervures testaceous. < J. 

 Length 5 mm. 

 Quetta. May. 



Smooth, shining, densely covered with white pubescence ; the base of the 

 metanotum irregularly rugose ; the areola widely separated from the base,, 

 semicircular. Pro- and mesopleurae smooth ; the meta-smooth at the base ; 

 the rest closely rugosely reticulated-punctured ; the centre at the base with 3 

 longitudinal keels. Temples roundly dilated ; the occiput roundly incised. 



Apart from the differences in colouration this species may be known from 

 C. niqricollis by the areola being semicircular and by the occiput not being 

 tranverse. In colouration it agrees with C. ruficollis, Cam., from Bombay. The 

 differences between them may be expressed thus : 



Areola extending from the base to the apex of the segment, widened 

 in the middle, narrowed towards the base and apex; a large 



square area on either side ; occiput transverse ; calcaria black ruficollis. 



Areola not extending from the base to the apex, semicircular ; no 



area on either side ; occiput not transverse, calcaria testaceous erythronotus* 



Ruficollis has the pubescence denser and longer, and the tubercles are red. 



Chelonin^e. 

 Chelonus areolatus, sp. nov. 



Black, the 4 anterior knees, tibiae and tarsi, the basal half of the hind 

 tibiae and the base of the tarsi narrowly, yellowish testaceous ; wings hyaline,, 

 the costa and nervures pale testaceous, the stigma black. Base of metanotum 

 with a large area, somewhat longer than wide, in the centre ; it is slightly 

 roundly narrowed at the base and apex. 9 • 



Length 3 5 mm. 



Quetta. May. 



Antennae 20-jointed. Face closely punctured ; the clypeus shining, its apex 

 depressed, broadly rounded. Front and vertex finely, closely punctured ; below 

 the ocelli finely closely transversely striated. Mesonotum finely closely punctur- 

 ed ; the apex and sides of the scutellum closely striated. Metanotum closely 

 rugosely punctured-reticulated ; in the centre are 2 keels, roundly curved at the 

 base, forming an area which is longer than broad ; it is irregularly reticulated 

 and has a stout keel down the centre ; the apical slope is closely, strongly 

 punctured : the lateral teeth short, broad. Pleura? closely punctured, more- 

 or less striated. Radius short, not reaching to the apex of the basal third of the 

 apical part of the wings ; it is roundly curved ; the basal two abscissae are 

 equal in length. Striatiou-reticulation on the abdomen strong at the base, 

 besoming gradually weaker towards the apex. 



Chelonus for tispinus, sp. nov. 

 Black, the apex of the 4 anterior femora, their tibia? and tarsi testaceous, a 

 broad band at and behind the muidle of the hind tibiae, the basal two-thirds
