II, p. 14, 1899. 'It is the Xiphidion fuscus (Fab.) mentioned by 

 Kirkaldy in "A Preliminary List of the Insects of Economic 

 Importance Recorded from the Hawaiian Islands," The Hawaii- 

 an Forester and Agriculturist, I, p. 184, 1904. It dififers from 

 descriptions of X. fuscum, 'however, in the following respects: 

 the posterior -margin of the lateral lobes of the prothorax are 

 more nearly straight, not "strongly sinuate;" cerci of male are 

 obtuse, not "acuminate," and the teeth are differently placed 

 (PI. XIV, figs. 8, 9); subgenital plate of male is truncate, and 

 not "slightly triangularly emarginate." X. fusciun is an Euro- 

 pean species and less likely to have reached these islands than 

 some species from the western coast of North America, or from 

 Asia or Australia. Our species dififers from all described species 

 from Asia and Australia. It comes nearer to X. spiiwsuni 

 Morse, (Can. Ent., XXXIII, p. 201, 1901), occurring in Cali- 

 fornia. Ft dififers from the latter species, however, by its color- 

 ation, being green, not "testaceous;" the spines on under side 

 of posterior femora are not "strong;" the antennae are much 

 longer; and the ovipositor is much longer, in fact our species is 

 quite distinctly larger in all measurements. At present the 

 original habitat of our species is a matter of considerable doubt. 

 Described from numerous specimens collected in Honolulu 

 and elsewhere in the Hawaiian Islands. 



Xiphidiuin latifroiis Redtenbacher. 



Redtenbacher, Monographic der Conocephahden, ° p. 212, 

 1891. 



What appears to be this species was collected at Bundaberg, 

 Australia, by Mr. Perkins. It agrees with Redtenbacher's de- 

 scription except t'hat it is the long-winged form; whereas, he 

 described it as being only short-winged. 



Another closely related Xiphidiuin was collected by Mr. Per- 

 kins. These species swarmed in some cane fields of Australia.
