30 Ilymenoptera from the Oriental Zoolojical Region. 



tlie bottom. The ventral keel extends to the apex of the 

 fourth segment. Head Uirge, wider than the thorax. Labrmu 

 hidden. 



The edentate mandibles refer this genus to the Heresiarchini, 

 It cannot well be confounded with any of the known genera 

 in that group. The parapsidal furrows and that on the meso- 

 notum are quite as distinct as they are in many Crypti_na3; 

 but in other respects the genus belongs to the Ichneumoninse. 

 The antennae are exactly as in the joppini. Characteristic 

 is the dilated at the base, clearly separated clypeus. In this 

 respect the clypeus shows an approach to what it is in 

 Gkiaglas, an East-Indian genus belonging to the same group, 

 but differing considerably otherwise. 



Allonotus riifus, sp. n. 



Kufous ; the red on the second and following segments of 

 the abdomen darker, more testaceous in colour ; a broad band 

 at the outer sides of the ocelli (continued as a narrower line 

 in front of them), the second abdominal segment (except at 

 the sides and apex), slightly more than the basal half of the 

 third and fourth segments, the fifth (except narrowly at the 

 apex), the sixth (except for a narrow white line at the apex), 

 and the seventh (except for a wide white band in the middle), 

 black ; the petiole has the bright red colour of the thorax ; 

 the gastrocoeli pale rufous. Legs coloured like the thorax, 

 except the apices of the four anterior tarsi broadly, the apex 

 of the hind femora narrowly, and the hind tibise and tarsi, 

 which are black. Antennse with the scape rufous, the 

 flagellum black, brownish at the base below, the middle with 

 a broad white band. Wings hyaline, the stigma fuscous, the 

 nervures black. ? . 



Length 10 ram. 



Kuching ; December (Hewitt). 



Face and clypeus smooth, the former pilose, the latter bare ; 

 the rest of the head smooth and shining. Exce{)t the meso- 

 notum (which is opaque and slightly shagreened), the thorax 

 is smootli and shining, as is likewise the abdomen (except 

 the second and third segments, which are slightly shagreened). 

 The thorax is three times longer than wide ; tlie scutellum is 

 not raised above the mesonotiun and is longer than wide ; 

 the metathorax is densely covered with a short pile.
