distad, penultimate segment three-quarters as long as wide, last 

 segment elongate ovate, three times as long as its greatest width, 

 with apex moderately acute. Subgenital plate with lateral margins 

 thickened, convergent, very feebly convex, to near median portion 

 where these thickened portions terminate, the brief meso-distal 

 portion of the margin weakly concave between the ridges which 

 indicate style bases, no styles being developed in this specimen. 

 Cephalic femur with ventro-internal margin armed with (twelve 

 and thirteen) spines which alternate slightly in length, ^'^ except 

 in area below femoral brush, which portion of the margin is supplied 

 with two or three minute spinulse (not included in the above count) . 

 Cephalic tibia with the more elongate spines of the ventro-external 

 margin the ninth, seventeenth, twenty-fourth and twenty-fifth on 

 one limb, the eighth, sixteenth, twenty-third and twenty-fourth 

 on the other limb,i^ not including the longer distal spine of this 

 margin. 



Body and limbs immaculate; apparently discolored, yellowish 

 brown. Eyes blackish chestnut brown. Tegmina and wings clear 

 hyaline, very strongly iridescent, except narrow marginal area 

 between marginal and mediastine veins, which in the tegmina is 

 entirely opaque, colonial buff, in the wings similarly opaque, colonial 

 buff, distad in this area. 



Length of body 21, length of pronotum 5, length of pronotal 

 collar 1.8, greatest width of pronotum 1.8, width of marginal field 

 of tegmen .9, length of wing 15.5, length of cephalic femur 5.3 mm. 



The type of this singular species is unique. 



4th Group, Nanomantes. 

 SCEPTUCHUSis new genus. 



The present genus is apparently nearest in relationship to Nano- 

 mantis Saussure. It is seen to differ from Nanomantis in the more 

 even contour of the occiput with juxta-ocular swellings very feebly 

 indicated, weakly convex, carinate shaft of pronotum, smooth 



"^ So numerous and elongate- are the spines of the opposed margin of the ceph- 

 alic tibia when the limb is flexed that the present specimen shows fhe majority 

 of the longer spines of this margin to have been broken, apparently by contact 

 with these. ] 



" The difference indicated here for the two limbs is due to the Ikct that one 

 limb has one less of the minute proximal spines than the other. 



'* Wand Bearer, in allusion to the manner in which the Mantida point with 

 their cephalic limbs. i
