ME. U. M'LACHLAN OS J!TEW SPECIES ETC. OE NEUKOPTERA. 237 



treme apex produced into a sort of tooth ; the apical margin and 

 apical half of dorsal sinuated; on the dorsal margin near the base 

 is a small black shining spot ; costal margin with numerous oblique 

 fuscous spots, a collection of fuscous spots on the costa beyond the 

 pterostigma ; a fuscous line at the postcostal furcation ; two large, 

 more or less confluent, fuscous spots in the upper part of the disk 

 towards the base ; a narrow oblique fuscous fascia before the middle, 

 broadest at its commencement below the radius, and becoming 

 gradually narrower until its junction with the dorsal margin ; a broad 

 oblique fascia beyond the middle, becoming paler and cloudy on the 

 dorsal margin, so that it appears as a very large blotch extending from 

 below the apex two- thirds across the wing, after which it is indistinct ; 

 a pale fuscous cloudy space before the apex, below the collection of 

 subapical costal spots; the tooth-like apical production fuscous; besides 

 these markings some of the principal veins are dotted with fuscous, 

 and smaller dots in the pterostigmatical region : posterior wings slightly 

 shoi-ter and narrower than the anterior ; the apex produced upwards 

 and ending in a strongly curved hook, the margins sinuated as in the 

 anterior ; the oblique costal spots are less numerous and do not extend 

 beyond the middle of the costa ; a collection of spots at the commence- 

 of the elevated apex, beyond the pterostigma ; a mark at the post- 

 costal furcation ; three broad transverse fasciae, one about the middle 

 - commencing below the radius, and almost interrupted in the middle, 

 produced towards the apt;x on the dorsal margin ; the second beyond 

 the middle, commencing on the costal margin, the edges sinuated ; the 

 third occupying the apex, dilated in the middle, so that it is almost 

 triangular in form : in all the wings the ptei'ostigmatical region is 

 somewhat opaque, and dirty whitish; all the veins and veinlets reddish, 

 becoming darker where thej* traverse the fuscous markings. Legs 

 dark pitchy brown or reddish brown, short and stout, rather thickly 

 clothed with short whitish hairs and strong blackish spines. Abdo- 

 men reddish brown, darker at the base, which portion is clothed with 

 fine whitish pubescence ; S, appendices short, not half the length of 

 the penultimate segment, curved, the apices thickened, hairy, the inner 

 side thickly set with short black spines. 

 This insect is most allied to P. contrarius, "Walker, but very 

 distinct, especially through the strongly falcate posterior wings. 

 With that species, and with P. gigas, Dalman, and P. moestus, 

 Hagen, it forms a peculiar group which no doubt will eventually 

 be generically separated, and to which the term Symmathetes may 

 be applied. The male above described is the only one known 

 in the four species. 



Palpares FULVUS, n. sp. Rufo-brunneus. Antennae nigree ; clava 

 acuminata. Caput rufo-griseum ; vertice valde fornicate, vitta media 

 nigra; fronte flava ; palpis nigris, gracilibus, labialibus perelongatis.
