688 FAUNA HAWAIIENSIS 



Of twenty-one females, one only was of the discolor var. but one or two of the 

 other twenty (typical green blackbtirni) showed the triangular dark facial area as in the 

 t above referred to. In reality this variety can hardly be considered as a true 

 intermediate form, but rather as a third constant variation, rare in either sex. 

 It is certainly interesting to find this peculiarity of marking occurring as a constant 

 specific character in B. tmica of which I have, since its description, examined 

 additional specimens. 



It would appear then that about one ^ in 13 of ^. blackburni is green, typical or 

 subtypical, the others being var. discolor, while of the females one in twenty-one only 

 is var. discolor the others being the green form. Consequently there is exhibited a 

 sexual dimorphism in B. blackburni, which is not yet quite complete, while a third form 

 is of uncommon occurrence in either sex, in some respects forming a slight intermediate 

 condition between the blackburni and discolor forms and resembling in colour another 

 species of the genus, very distinct from and much rarer than blackburni but occurring 

 with it. 



I ought to add that all the specimens here considered were taken in the same 



locality. 



GRYLLOIDEA. 



(i) Gryllus, sp. ? 



A commonplace species of Gryllus appeared in Honolulu in 1901 and has now 



spread into the country. 



Paranemobius Alfk. 



(i) Paranemobius schauinslandi Alfk. 



What I take to be this species is an evidently' imported species, found in dirty and 

 dusty houses, in closets, cellars, etc., in Honolulu and elsewhere. 



Leptogryllus p. 

 (i) Leptogryllus cylindricus, sp. nov. 



Testaceous or ferruginous, becoming often more or less discoloured after death, the 

 front tibiae and femora with faint fuscous spots or annulations, apex of first, the second 

 and apex of third joints of hind tarsi and sometimes of the middle ones infuscate. Tip 

 of ovipositor blackish, with numerous small teeth on each side, the apical ones the 

 larger. Hind femora very slender, with many small fuscous spots outwardly. Tegmina 

 squamiform, about covering the metanotum in the male, smaller in the female, their 

 inner margins not nearly touching the middle line. Ovipositor of the female very long, 

 considerably longer than the hind femur. Length of body without ovipositor 15 mm., 

 ovipositor 13 mm., hind femur 10 mm. 



Hab. Kauai, about 2500 ft. 



' An examination of the figures of P. schauinslandi has since convinced me that it is not the household 

 insect above referred to, and it is still unknown to me. R. C. L. P.
