Plagithmysits danviniauits attached to Sophora chrysophylla. 



Two very desirable species viz.: P. sulphuresccns and P. 

 z'iciniis, captured in these forest regions by Dr. Perkins, were 

 not observed and have yet to be re-taken in this and adjacent 

 country. No examples of either of these last-named species 

 are in local collections. P. sulphuresccns is said to be attached 

 to a species of Urcra, and P. zncinus to a species of Pelea. 



While the series of P. vitticollis exhibited were undoubt- 

 edly attached to a Perrottetia f when captured, yet this species 

 has been taken before, somewhere in the neighborhood of 

 Kilauea, on akala (Rubus macraei), and is so recorded. Fur- 

 ther observation of Rubus hazvaiicnsis and Rubus macraei 

 should be made by those who search for our native longicorns 

 in and around Kilauea. 



At Kilauea, P. varians, P. bilineatus, and P. darzvinianus 

 appear to be the most common of all the species in the region, 

 although most of the others are not uncommon when the trees 

 to which they are attached are found to be in the right con- 

 dition for attack. Heretofore P. perkinsi, P. Z'itticoUis, P. 

 giffardi. and P. lamarckianus have been found by the writer to 

 be the least abundant in individuals. No doubt the rare P. 

 sulphurescens and P. vicinus will be taken in similar numbers 



* The series of this species was taken in North Kona. It has not as 

 yet been taken at Kilauea. 



** This was taken in the dense wet forest in upper Puna. 



f Taken from three trees in dying eondition, all near each other.
