I04 FAUNA HAWAIIENSIS 



(13) Clytarlits annectens, sp. nov. 



Gracilis, rufus, dense punctatus, elytris in dimidio apicale guttis minutissimis 

 albidis ; pedibus basi antennisque flavis : femoribus posterioribus clava elongata, 

 suboblonga. Long. 7*5 millim. 



Only one individual, a male, has been found of this species which might be placed 

 with as much propriety in Plagithmysus as in Clytarliis. The thorax is not crested 

 along the middle, but there is a slight anterior elevation, and numerous minute irregular 

 scabrous elevations behind it : the sculpture is excessively dense and fine and there is 

 almost no pubescence. The elytra are much narrowed behind, and are densely and 

 rather closely punctured : there are some excessively minute spots of white hairs on the 

 apical part near the suture, and also a few below the shoulder. There is a dense white 

 pubescence on the sides of the breast. The middle legs have a long club and a rather 

 short but slender stalk ; on the hind legs the stalk is longer and slender, so that I refer 

 the species to Clytarlus rather than to Plagithmysus.

Mr Perkins has obtained fine series of this genus, enabling me to feel pretty 

 certain that the species are fairly distinct, and can be readily recognised notwithstanding 

 their being in many cases very closely allied. No species has been found on two 

 islands. Apparently each species is confined to one kind of tree. Nine of the species are 

 attached to one or other of the precinctive Acacias. Closely allied species are attached 

 in certain cases to the same species of tree, but it would seem that they are in this case 

 geographically separated. P. blackburni and P. darwinianus are both attached to 

 Sophora chrysophylla, and both occur on the island of Hawaii, but they have not been 

 found in the same locality there. Closely allied species {^P. darwinianus, varians and 

 lainarckianus) live in the same locality but are attached to different trees.
