Ilymcnoi (era from the Khasia llills. oil) 



oblique slope ; from the middle of tlie areola a transverse 

 keel runs to join a longitudinal one placed inside the spiracles. 

 There is a short shallow furrow on the sides of the meso- 

 sternum at the base; the sternal furrow is wide at the 

 apex. Petiole smooth and shining ; the red base of the 

 second abdominal segment is closely, distinctly, and longi- 

 tudinally striated; the black part is strongly aciculated.

 Ampulex montana, sp. n. 



Length 16 mm. ? . 



Hab. Khasia Hills. Coll. Rothney. 



This species agrees closely with A. trigona, Cam., in size 

 and coloration, and in having the head obhquely narrowed 

 behind the eyes^ but may be known from it as follows : — 



The upper third of the mesopleuras coarsely deeply puuc- 

 tured ; the sides of the mediau segment closely, distinctly, 

 tr.tusversely striated ; the vertex not distinctly furrowed 

 in the middle behind montana. 



The upper tldrd of the mesopleuras not distinctly punc- 

 tured ; the sides of the median segment not closely, 

 regularly, transversely striated ; the vertex distinctly and 

 deeply furrowed in the middle behind tvujona^ Cam. 



Antennse entirely black ; the third joint nearly as long as 

 the following two united. Head green with bluish tints ; 

 the sides and apex of the clypeus and its central keel black. 

 There is an oblique irregular row of punctures on the sides 

 of the vertex ; the antennal tubercles are large, and their 

 keels extend halfway up the front ; between them is an 

 elongated tubercle. The clypeus has a row of punctures 

 near the apex ; its middle at the apex is bluntly rounded, 

 with a shallow rounded incision on either side. The head 

 is distinctly obliquely narrowed behind the eyes. Prouotum 

 large ; the apical part somewhat longer than the width at 

 the base ; smooth, the base depressed in the middle and with 

 a distinct longitudinal furrow on the basal half. Mesonotum 

 smooth in the middle; the sides with some large scattered 

 punctures. Behind the scutellum is a row of stout longi- 

 tudinal keels, which are weaker in the middle than on the 

 sides. Median segment completely transversely striated ; the 

 striae on the outer edge stouter than on the rest of the 

 segment; the apex is smooth; the three central keels reach 

 to this smooth part ; the apical slope is transversely striated 

 in the centre ; the sides and top are irregvdarly striated- 

 reticulated. The up[;er part of the mcsopleuric from abo\e
