164 HTMENOPTEKA. 



behind the eyes. Thorax coarsely punctured, and covered with a pale pubescence. Scu- 

 tellum flat, narrowed considerably behind, where it is truncate. Metathorax depressed 

 in the centre, the areae all distinct — the supramedian a little longer than broad, and 

 almost truncate at the base and apex ; postero-median all present, the central with straight 

 sides ; the portion behind the apex of the supramedian is yellow to the extreme apex of 

 the metanotum. The petiole is black, as is also the base of the postpetiole ; it is longi- 

 tudinally striated, and yellow at the apex. Abdomen closely punctured, its apex rather 

 blunt ; the black band on the second segment is behind the gastrocceli, which are 

 shallow and indistinct, and is less distinct than upon the others, being almost divided 

 into three ; the bands on the third and fourth occupy nearly half the segment, on the 

 fifth more than the half. The tegulae and a spot in front, the tubercle below them, and 

 the prothorax in front above are clear yellow. Areolet 5-angled, the sides narrowing 

 towards the upper part. 



60. Ichneumon sublutus. 



Eab. Mexico (SalU). 



In coloration this species agrees with the preceding, except that the antennae have a 

 broad reddish band in the middle. The mark on the metathorax is ferruginous, not 

 yellow, the apex of the postpetiole being also of this colour. The four front coxae are 

 entirely yellow behind. The scutellum is broader than long, not longer than broad, as in 

 I. turpiculus. The thorax is not so densely pilose. The gastrocceli are more distinct, 

 transverse, and finely aciculated ; and there is no black on the second segment. The fifth 

 and following segments are missing in the specimen ( S ) before me. Another good mark 

 of distinction is that the third joint of the antennae is not much longer than the fourth. 



A smaller species than I. turpiculus. 



61. Ichneumon multiplagiatus. (Tab. vill. fig. 5.) 



Mger, flavo-maculatus ; abdomine rufo, basi nigro etflavo maculato ; pedibus flavo-testac'eis, femoribus tibiisque 



nigro-lineatis ; alis hyalinis, stigmate testaceo. $ . 

 Long. 15 millim. 



Hah. Guatemala, San Geronimo (Champion). 



Closely punctured, but not strongly on the head and thorax. Antennae stout, semi- 

 involute, a little thickened and compressed beyond the middle. Front projecting in the 

 centre ; clypeal foveae large and deep, a shallow furrow joining them. Eyes bordered 

 all round. Hollow above the antennae deep, smooth, shining, black, the black con- 

 tinued as a broad band to the back of the head, which is entirely of that colour. There 

 is a broad black band on jthe pronotum and on the side of the prosternum. Mesonotum 

 black, except two straight narrow lines running from the middle to the pronotum, and 

 two curved ones from the scutellum to the tegulae. Scutellum flat, broad, not much 

 longer than broad, and not much narrowed towards the apex ; black, the sides and 

 apex bordered with yellow ; there are two yellow marks at the base, joining the above-
