114 PIMPLINE ICHNEUMONIDAE 



between the lateral plates of the scutellum (Scl.2), so that its 

 lateral margins are concealed. Both the prescutum and scutum 

 are transversely rugose. The lateral margin of the prescutum 

 is deflexed. The anterior portion of this deflexed margin is 

 overlapped by the dorsal border of the pronotum. From the 

 top of the pronotal lobe, just above the first thoracic spiracle, 

 is a ridge extending to the anterior corner of the lateral lobe 

 of the scutellum, behind which point, the margin of the scutum 

 is concealed by this lobe, as already stated. Below and behind 

 this ridge, the scutum bends abruptly and is somewhat hollowed, 

 the lower margin of this portion of the plate extending backward 

 until opposite the front end of the lateral lobe of the scutellum. 

 The margin now turns upward and forms a suture with the front 

 margin of the lateral lobe of the scutellum. 



The scutellum (Scl.2) consists of a median raised portion and 

 two deflexed regions. From the front of the median portion of 

 the scutellum a ridge runs downward on the side of the body 

 toward the lower, hinder angle of the plate, and may be considered 

 as marking the line between the median portion and the lateral 

 lobe. The lateral lobe, as thus indicated, is approximately 

 rectangular, its lower, hinder angle being somewhat drawn out 

 and its lower border somewhat emarginated. The hinder margin 

 of the median portion of the scutellum is practically a straight 

 line, running obliquely backward on either side. 



The fore wing has a much elongated attachment to the body, 

 its humeral angle appearing just behind the pronotal lobe, and 

 its internal margin near the lower, posterior corner of the lateral 

 lobe of the scutellum. Beneath this wing attachment lies the 

 upper margin of the mesoepisternum (Eps.2). 



The tegula (Tg.) which lies over the anterior portion of the 

 base of the wing is a small chitinous plate, which appears to be 

 attached medially to the front end of the hollowed portion of the 

 scutum, just below the front edge of the ridge already described. 

 Its real attachment and relation to the wing are considered under 

 a separate heading elsewhere in this paper. Two tiny basal wing 

 sclerites lie beneath the costal and anal regions of the wing. 



As in the prothorax, the episternum (Eps.2) constitutes the 

 greater part of the pleural region. It is fused with the sternum 

 (S.) which has a narrow, deep, mid-ventral groove extending
