FAMILY IV. PHASMIDJ3. THE WALKING-STICKS. 



on meso- and metanotum, is a striking character. The sides of the 

 seventh and eighth abdominal segments also bear a curved black 

 stripe, and the snbapical spines of under surface of middle and 

 hind femora are shining black. 



II. MAXOMERA Rehn & Hebard, 1907, 283. (Gr., "thin" + 



"thighs.") 



Very closely allied to Diapheromera. Head more slender, 

 smooth, swollen in front, twice or more as long as broad, attached 

 horizontally to the thorax; an ten me about two and a half times 

 as long as the front femora ; middle femora armed beneath with a 

 slender subapical spine, hind femora unarmed; cerci of male 

 stout, cylindrical, pubescent, decurved and incurved, sometimes 

 crossing near middle and armed on the inner side at base with a 

 spine or tubercle (Fig. .">4, c] ; cerci of female slender, lanceolate, 

 about as long as the ninth abdominal segment (Fig. 54, d.). 



This genus is characterized very briefly 

 by its authors thus: "From Diaplieromera,, 

 Maiionirra can be separated in the male by 

 the slender head, absence of caudal femoral 

 spines, uninflated median femora and more 

 elongate abdominal appendages." Now the 

 middle femora of the male of M. Watclileyi 

 are distinctly inflated, and the cerci of the 

 male of no species of Manonicra are more 

 elongate than those of D. fcniorata, while 

 the long female cerci are paralleled in that 

 sex of D. rcliri. This leaves only the more 

 slender head and the absence of spines on 

 hind femora as the valid characters separat- 

 ing the two genera. Since these femoral 

 si >i nes are often absent in the females of Dia- 

 plieroniera it will be readily seen that Hanoiiicra has a very pre- 

 carious standing. The species at present ascribed to the genus 

 may be separated as follows : 



KEY TO THE SPECIES OF THE GEXUS MANOMERA. 



a. Middle femora of male not or scarcely thicker than the hind ones; 



head slender, more than twice as long as broad. 



&. Seventh, eighth and ninth abdominal segments of male together 



one-half longer than sixth; ninth segment cylindrical, distinctly 



longer than wide, male, longer than prothorax, female; cerci of
