Hcbard — Dcniiaptcra and Orthoptcra of Hazcaii 359 



Kuliouou \'alley, Oahu. Vll. 25, 1916 and XII, 22, 1918, (P. 

 H. Timberlake), 2S , [Timl^erlake and Hebard Colls.]. 



Kauai, 3500 to 4000 feet. III, 29 to IV, 13, 1919, (J. A. 

 Kusche), 2$, I juv., [Hebard Coll.]. 



The intensively colored specimens have the limb markings heavy and 

 the head and pronotum pale but heavily marked and suffused to varying 

 degrees with very dark brown. Many of the other specimens have the head 

 and pronotimi immaculate, rather dark reddish-brown. 



In the series from Oahu, a number of females fit the descrip- 

 tion of P. c.viguiim Perkins, as do the males, except that in none 

 of the males are the tegmina quite so short as 4 mm. The insect is 

 clearly one of the most vvddely distribttted and plastic members of 

 the genus, and the synonymy of exigtiitiii appears to be very pos- 

 sible but can not be determined without examination of the pair 

 from the W'aianae Alountains (Oahu) upon which that name is 

 based. 



Examples of the present species, many showing close superfi- 

 cial resemblance to individuals of P. pacificuni (Scudder), may be 

 quickly separated from them by the lesser number of veins in the 

 lateral fields of the tegmina and the ovipositor, the transverse 

 suture of which is meso-distad, instead of mesad. The latter type 

 is peculiar to pacificuni, of the known species of Paratrigonidium.

These females differ from those of P. various Perkins before us in 

 their smaller size, with dorsal surface of head, pronotum, and tegmina sol- 

 idly dark brown, causing the paler lateral margins to be conspicuous.
