104 HYMENOPTERA OF SARAWAK. 



ed with black hair, as is also the sheath of the ovipositor. The 

 apical abscissa of the radius is as long as the basal two united. 

 Recurrent nervure almost interstitial ; below it is a hyaline spot. 

 Abdomen longer than the head and thorax united ; its apex 

 bluntly pointed, the hypopygium larger, projecting. 



Trichiobracon, gen. nov. 



Hind coxae with a large, curved and a shorter, minuter, 

 straighter spine in the middle above. Pobrachial transverse ner- 

 vure in hind wings joined to the transverse praabrachial, roundly 

 curved towards the apex of the wing but not reaching it ; pobra- 

 chial nervure short, not reaching to the middle of the wing ; 

 from near its apex a stouter oblique nervure runs to the prasbra- 

 chial, forming a large, closed cellule at the base of the pobra- 

 chial. Stigma large, the radius issuing from behind its middle. 

 Transverse median nervure recived distinctly beyond the trans- 

 verse basal; the recurrent nervure received in from of the 

 1st transverse cubital. Occiput and cheeks margined. Malar 

 space large. Mesopleurce with a distinct, crenulated fur- 

 row. Parapsidal furrows deep. Median segment large, closely 

 reticulated ; its sides at the middle of the apical slope with a 

 small, but distinct, rounded tubercle. Basal segments of the 

 abdomen closely longitudinally striated. Cerci long, slender. 

 Legs short and stout ; the metatarsus not much longer than the 

 2nd joint ; cerci minute. Temples broad. Ovipositor projecting. 



The abdomen is broad, not much longer than the head and 

 thorax ; basal segment broad ; the other segments are broader 

 than long ; hypopygium short, vertex not much depressed. 



This genus is allied to Spinaria. It may be identical with 

 Acantliobracon, Szep ; but the description of that author is too 

 short to enable me <to decide this. So far as the description 

 goes Szepligeti's genus differs from mine in the 3rd abscissa of 

 the radius not reaching to the apex of the wing and no mention 

 is made of the pobrachial nervure in hind wings being roundly 

 curved, directed downwards from the pradbrachial towards the 

 apex of the wing, not obliquely sloped, straight from bottom to 

 top as usual. This nervure, in fact, has the appearance of being 

 a 2nd cubital nervure and may not be the equivalent of the
