1. a 1. mi 11 with line of cilia show ing from outer end on each aide about hah 

 to median end. Median piece rather broadly ouneate but with sides, except- 

 ing toward anterior end, weakl) incurved, convex; the anterior edge bulging 

 forward convexly; the length less than twice the greatest width, the ratio 

 being near ;vi: 17. 



Mandible with fourteen lamellae of which the ordinary onet have the distal 



teeth long and the median and proximal Ones \<i\ short. First lamella with 

 eighteen to twenty teet h, these reduced regularly from t In- distal Ones prOXttnad. 



A median lamella with about thirty-seven teeth. 



Efital angle of coxa of first maxilla produced slightly ectad of rrphalad, 



acute. Posterior corners of ooxosternum of second maxillae acutely and 

 considerably extended; pores moderately large, suboval; a median non- 



areolate hand set off from lateral non-areolate regions. 



Prosternum armed. Prehensors with the typical teeth. Claw at base 

 with a single nodule or tooth. Femuroid with proximal tooth small, the distal 

 one greatly exceeding it, much as in Mecidocephalus philippinus Chamb. 

 though the disproportion is not so great; conical, narrowly rounded distally. 

 The next two articles armed, the tooth of the second much exceeding that of 

 the first. 



Sternal impressions furcate, the angle obtuse. 



Ventral plate of pregenital segment strongly narrowed caudad, notched on 

 each side in front of caudal end. Coxopleural pores very numerous, small and 

 very small, the pores of the two sizes typically not much differing in number. 



Pairs of legs, forty-nine. 



length, to about 55 mm. 



154. ECTOPTYX KABASANUS, sp. nOV. 



Type — M. C. Z. 2,049. Fijis: Kabasa Lau (W. M. Mann). 



Dorsum, and to a less marked degree the pleurae and sternal region, dark- 

 ened by a network and mottling of black as in F, labasanus, the pregenital 

 segment and anal region in the type abruptly paler and a median pale line 

 evident on dorsum in posterior region. Head and prehensors chestnut. 



ilead of same general form and proportions as in labasanus, with the clypeal 

 region similar. 



Labrum with line of cilia exposed on each side as in labasanus. Median 

 piece similarly broadly cuneate.but the sides straight or incurved, not convex, 

 and the piece only slightly more than once and a half longer than the greatest 

 width. 



The species is readily distinguished by the characters of the mandible. 

 Nineteen lamellae are present. The median ones have the distal teeth long 

 and the others shortened in the typical manner. First lamella with twenty- 

 three teeth which are reduced proximad. A median lamella with about 

 fifty-five teeth. Margin below first lamella smooth.
