\vhich has no correlated color nor fore wings, but is peculiar to 

 itself. 



At first I take the European species with lengthened proximal 

 funicle joint (Stepkanodes) Polynema enockii (Girault). The 

 females differ as follows: Funicle joints 4 and 5 are shorter and 

 subequal in reduvioli and joint 5 is not nearly as long as joint 3 

 but distinctly shorter; also the fore wings are not quite so large, 

 more graceful, bearing about 25 lines of fine discal ciliation; other- 

 wise, I can not distinguish the two species; they are remarkably 

 similar; the antennal scape in reduvioli bears the peculiar sculpture. 

 The males of enockii differ from the males of reduvioli in having 

 distinctly longer joints in the flagellum. The coloration of both 

 species is the same. In regard to the North American psecas, the 

 Hawaiian species, comparing the females first, differ thus: Only 

 in the fact that the second funicle joint is shorter in relation to 

 the first in the North American species, but in the same species 

 I have seen a specimen where the two joints were subequal; this 

 difference is certainly very small and it is extremely difficult to 

 know what to do in such cases. By comparing the males, it is 

 seen that they differ as in the case of enockii, the flagellar joints 

 in psecas being distinctly longer. For the present, therefore. I 

 leave the species separate, though they form suspicious units. In 

 one specimen of psecas, the second funicle joint was yellow like 

 the first. 



On November 4, 1911, I captured a single female Polynema 

 from a window around the veranda of a private residence at 

 Kuranda, North Queensland, a locality a few miles distant from 

 the nearest sugar-cane area. This species bore a long proximal 

 funicle joint of the antenna and as expected closely resembled the 

 foregoing species. I now compare it with them. It resembles 

 all but more nearly enockii and reduvioli, differing from the former 

 in bearing fore wings like the latter; thus, as concerns the antenna 1 , 

 it is intermediate or nearly between reduvioli and psecas. From 

 the Hawaiian species I am unable to separate it, so that the species 

 is common to the Sandwich Islands and Australia. From what 

 Perkins states in the original description of his species (reduvioli} 

 I have not much doubt -but what it is the same as hawaiiensis 

 of Ashmead. In the Australian specimen of reduvioli, the proximal 

 funicle joint was shorter than usual, but there seems to be con- 

 siderable variation in this respect, as I have experienced with 

 psecax. Hence, the English species is the most distinct, while 

 the North American and Hawaiian forms are very closely allied 

 if not the same. 



Here we have specimens of at least two distinct species of 

 Polynema, and probably three, occupying an enormous area of the
