Eucnemids are less numerous, the large black Fornax on Koa 

 trees being the most conspicuous and always attainable. With 

 it the large Cistelid Labetes hawaiiensis is also always to be found. 



Of weevils Acalles lateralis, callichroma, melanolepis , tuber- 

 culatus, and one or more undescribed species are all rare. None 

 have been collected in Olaa, where other species must occur. 

 Dryophthorus squalidus, distinguendus , and peles are the common 

 Kilauea species; gravidus, dedivis, modestus and insignis are 

 found at lower elevations, though I have not noted them from 

 Kilauea, nor should I have taken these common insects, had I 

 seen them. Pentarthrum prolixum is abundant, and often very 

 large; Deinocossonus nesiotes rare, Nesotocus munroi always at- 

 tainable both at Kilauea and in Olaa. Oodemas requires special 

 study, individuals being very abundant, but the species are as 

 yet yery imperfectly known, being excessively difficult to deter- 

 mine. Of the Scolytids several species of Xyleborus are found, 

 and others again towards Hilo. It is especially desirable to 

 obtain the rare males and associate them with their females, to 

 which they bear no superficial resemblance. On my last visit 

 I was able to take the sexes of two species in company. 



The Longicoms of the genus Plagithmysus and Clytarlus are 

 better represented than in any other locality in the islands. No 

 less than a dozen species are to be found in the limits of a little 

 over two miles of country, and a visit to Olaa may yield one or 

 two other species. I discovered a new* Plagithmysus recently 

 about half a mile from the Hotel, near the vegetable garden. The 

 species are P. vitticollis (Kau side), P. longulus (Hilo side), P. 

 bishopi, P. bilineatus, P. perkinsi, P. varians, P. danvinianus, 

 P. lamarckianus , P. sulphurescens , P. giffardi and P. gracilis 

 (which I believe is distinct from P. bishopi). Also Clytarlus 

 filipes, C. claviger, and in Olaa C. abnormis. 



Parandra puncticeps and Aegosoma reflexum are both common. 



HYMENOPTERA. 



About fifty bees and wasps are here named, mostly from the 

 immediate neighborhood of the volcano, but I have added a few 

 that are easilv obtained in Olaa or near Hilo. It will be seen 



*P. giffardi sp. nov. very closely allied to P. sulphurescens Sh., but at 

 once distinguished by the entire absence of a basal fulvous or rufescent 

 area on the elytra. It is attached to a species of Myrsine.
