closely, obliquely striated, striae closer at base. Base of 

 mesopleurse striated, the strife more or less curved, and running 

 from top to bottom ; the centre weakly punctured, apex from 

 near the top striated, striae at the base stronger, more oblique 

 and wider apart than they are at apex. Mesonotum finely, 

 not very closely, punctured ; apex of middle lobe longitudi- 

 nally striated. Length, 12 ; terebra, 5 mm. 



A few points of generic importance may be drawn from this 

 species, supplemental to those given in my description of the 

 genus in the Proceedings of the Zoological Society (1901, 233). 

 The mandibles apparently do not meet in front ; their two 

 teeth are short, equal in length, bluntly rounded, and sepa- 

 rated behind by a furrow. Occiput roundly incised, margined. 

 The smooth basal part of the metanotum is bounded by a 

 roundly curved keel, which, at the sides, extends to the base 

 of the metanotum, inclosing the spiracles, which are oval, 

 and twice longer than wide. Antennae slender, 27-jointed, 

 the basal joints of flagellum elongated, the first a little longer 

 than second. The fifth and sixth abdominal segments united 

 are as long as the fourth ; the sixth is the smallest, about one- 

 half the len,(i;th of fifth ; the penultimate is as long as the 

 second, and one-fourth longer than the last, which bears long 

 cerci. Legs long and slender ; claws simple, small ; hind coxae 

 as long as first abdominal segment. The disco-cubital nervure 

 is broadly, roundly curved. 



Xanthocryptus belongs to the Xorides rather than to the 

 CryptincB, but it is not quite typical in some respects. In 

 Ashmead's arrangement of the Xorides (BulKU.S.Nat.Mus., 

 xxiii., 61) it runs near to Pevosts, with which it cannot be con- 

 founded.
