intervening segments with two rows of inconspicuous reddish 

 testaceous markings, one on each side of the middle ; all segments 

 (except the last) lobed at the sides and provided with a rather 

 strongly impressed median channel, the edges of which are slightly 

 raised ; the margins very fineJy serrate. 



Head completely hidden beneath the prothorax, corneous, nar- 

 rowed and truncate in front ; a large prominent ocellus on each 

 side. Antennae rather long, somewhat flattened, robust, placed at 

 the sides of the head, 4-jointed, the 1st joint long, 2nd much 

 shorter, slightly narrowed at the base, 3rd about twice as long as 

 the 2nd, obliquely truncate at the extremity, 4th very minute, 

 inserted in a groove at apex of 3rd near the internal angle. 

 Mandibles prominent, falciform, and simple. Maxillse elongate. 

 Maxillary palpi short, robust, composed of three joints which 

 gradually decrease in width towards the apex. Labial palpi 2- 

 jointed, minute. Near the base of each maxillary palpus is a 

 minute apparently 2-jointed appendage.* First thoracic segment 

 at the base about one-third broader than long, greatly narrowed in 

 front; the anterior margin arched, strongly re flexed, slightly emar- 

 ginate in the middle ; the sides strongly reflexed, slightly sinuate 

 on each side just behind the anterior angles, which are not very 

 prominent ; 2nd and 3rd thoracic segments short, about three 

 times as broad as long, the sides reflexed, the angles rounded. 

 Abdominal segments gradually narrowed to the apex, 1-7 like the 

 segments of the thorax, 8fch emargi^ate behind, 9th much 

 narrower than the preceding, truncate. Beneath exceedingly 

 finely granulate, the 1st to 7th abdominal segments provided on 

 each side with a deeply impressed line, dividing the outer plate- 

 like portions from the middle of the segments. Stigmata nine 

 pairs, two pairs placed on tubercles upon the meso- and meta- 

 thoracic segments respectively, and seven upon tubercles within 

 the plate-like divisions on the first seven segments of the abdomen. 

 Legs rather short ; claws simple. Length 9^ mm. 



* As I have no specimen for dissection I am not able to describe the 

 mouth-structure as accurately as I could wish.
