Descriptions of New Species of Parasitic Hijmc boptera. 33 



the face in the middle closely, transversely striated. Clypeus raised, 

 clearly separated. Mesonotum closely, finely punctured, the sides 

 and centre dark brown in the middle. Post-scutellum keeled down 

 the middle. Metanotum more closely, but quite as distinctly punc- 

 tured as the mesonotum. Back of abdomen longitudinally rugosely 

 punctured, most strongly on the apical segments ; there is a lateral 

 oblique branch to the furrow on the third and fourth segments. The 

 abdomen is not wider than the thorax ; it is as long as it ; the last 

 segment is produced downwards below the level of the penultimate. 

 Palpi long, 2 . 



Length 5 mm. ; terebra 4 mm. 



Southern Ehodesia. Sebakwe. 



CHELONUS, Jur. sec. Szep. 

 a. Two white spots on base of abdo^nen 



Chelonus erythropus, sp. nov. 



Black, the legs red, the coxae and tarsi darker coloured, the hind 

 tarsi black ; antennal scape red ; a white band near the base of the 

 hind coxae, two lai^ge square marks near the base of the abdomen on 

 the sides ; wings hyaline, the nervures and stigma black. 9 . 



Length 6 mm. 



Cape Colony. Neighbourhood of Cape Town. 



Head closely, finely rugose ; the front depressed, obscurely, finely 

 transversely striated. Mesonotum alutaceous, finely, irregularly 

 longitudinally striated. Scutellum finely, closely, distinctly punc- 

 tured, the sides distinctly margined and with a crenulated belt below 

 the keel ; the notum at the sides of the scutellum smooth, shining, 

 impunctate, bare. Basal half of abdomen finely, irregularly striated; 

 the white spots become slightly obliquely widened on the inner side ; 

 the apical part of the abdomen is alutaceous, opaque. The second 

 cubital cellule is obliquely narrowed at the apex ; the second trans- 

 verse cubital nervure is faint, almost obsolete ; the basal two 

 abscissae of the radius are equal in length, thick, the basal thicker 

 than the second ; the nervures are black ; the costa at the base of 

 the stigma white. 



The base of the metanotum is depressed, furrowed ; there are 

 eight stout keels on the centre of the furrow, dividing it ; down the 

 middle of the metanotum are two keels, forming an area slightly 

 longer than wide. The front legs are tinged with yellow. The 

 sides of the metanotum at the top project into teeth.
