This male apparently represents the opposite sex to that of the female 

 described as voseitm. It is of considerably larger size, however, and addi- 

 tional material from Maui may show the presence on that island of an 

 undescribed species. 



In the present specimen the caudal portion of the pronotum is dark, 

 the cephalic portion, head and limbs apparently rose-color in life, the 

 antennae, tegmina and cerci light-yellowish and immaculate. 



Length of body 8.7, length of pronotum, 1.35, cephalic width of pro- 

 notum 1.85, caudal width of pronotum 2.45, length of tegmen 6.8, width of 

 tegmina 3.7. length of caudal femur 5.9 mm. 



The genital valves are retracted and consequently have not been exam- 

 ined in this unique specimen.

The large size of this species readily distinguishes it from the 

 other forms of the genus known from the island of Hawaii. 



The lateral projections of the genital valves are moderately heavy and 

 elongate in males of gi-aiidc, curving gently outward and then more strongly
