534 FAUNA HAWAIIENSIS 



C. blackburniae. 



C. blackburniae, huj. op. iii. p. 172. 



I have described and figured the ova, and described the nymphal stages (1907, 

 op. cit. p. 144, figs. 2 — 4). Dr Perkins writes " I have seen it swarming near the 

 coast on Dodonaea as well as in the mountains. I never saw it on Koa in anything 

 like such numbers as on Dodonaea. The latter covers acres of land where is no Koa. 

 The fact is it is partial to ' pods ' and ' capsules ' and the tree itself is of minor 

 consideration, if it bears these." Maui should be added to the list of islands. 



[Van Duzee (1905, Bull. Amer. Mus. xxr. 207) has cited Piezodorus rubrofasciatus 

 as a Hawaiian Insect, but in error. See Kirkaldy, 1908, P. Haw. E. S. i. 172 and 187. 

 Oshanin has given these islands as a habitat of Carpocoris ptidicus van fuscispina, also 

 in error.] 



Subfam. CYDNINAE. 



Geotomus pygmaeus Dallas. 



G. pygmaeus, huj. op. iii. p. 172. 



This little species is common under dried cow-dung, and under stones. It is 

 nocturnal, coming to "light" in the evenings. Add Kauai and Lanai to the islands. 



Fam. LYGAEIDAE. 



Ithamai' hawaiiensis Kirkaldy.

Dr Perkins writes, " this species is not attached to Sida, it abounds on Molokai at 

 3000 ft. on other plants, and at the Volcano (Kilauea), and as high as 8000 — 10,000 ft. 

 on Haleakala. You refer merely to the coast-line." It has been common in Kaimuki 

 this year (1908) on Sida cordifolia, but is attacked by Zelus refiardii. I have briefly 

 described the eggs and first nymphal instar (1907, P. Haw. E. S. i. p. 149). Add 

 Hawaii to the islands. 



This species, although unknown elsewhere, must be a recent introduction as it was 

 not taken by Blackburn who would certainly have collected it near Honolulu had it 

 been here then. 



Rhopalus hyalinus, Fabr. 



R. hyalinus, huj. op. iii. p. 1 70. 



I have described the ova and nymphs (1907, op. cit. pp. 146 — 8). This has been 

 common this year on Sida cordifolia in Kaimuki, as well as on Sonchus oleraceus, its 

 more natural food plant. It feeds also on Euphorbia cordata and is preyed on by Zelus 

 renardii. Add Kauai to the islands.
