Culcoptcra frotn the Hawaiian Islands. 43 



Ibrra of the anteniia3, and its dull, iinpunctate head and 

 thorax, this species has some resemblance to D. latifrons, 

 it is really very distinct from it, the middle coxa3 being 

 widely separated. 



Found on Freycinetia, in the mountains of Kauai. 



Ohs. — As it is doubtful whether these minute Hawaiian 

 Aleocharini are correctly associated Avith the European 

 Diesfota Mayeti, I give below a brief enumeration of 

 such of their characters as I have been able to observe. 



Labial palpi elongate and slender, 2-jointed, project- 

 ing beyond the labrum ; middle coxa3 not contiguous, 

 sometimes rather Avidely separated, the metasternum ad- 

 vancing far forwards between them, so that of the inter- 

 coxal space more than half the length is appropriated 

 by the metasternum. Tarsi short and rather stout, the 

 anterior and middle ones 4 -jointed, the hinder ones 

 5-jointed ; tibia3 rather stout, without spines. Antennse 

 but little elongate ; head broad, without neck, but little 

 immersed in the thorax. Thorax narrower than elytra, 

 transverse, narrowed behind. 



These insects seem allied to Epijjeda, Rey, from which 

 they differ, by the elongate and slender labial palpi, and 

 the more widely separated middle coxre, as well as by the 

 form of the thorax. The form of the mesosternum, and 

 the separation of the middle coxjb are, in fact, inter- 

 mediate between the two " rameaux," Diestotates and 

 Placusates of the French author; for, while the meso- 

 sternum descends but little between the coxfe in all the 

 species (the character of the Diestotates), its apex is 

 truncate in some of the species (as in Diestotates^, pointed 

 in others, as in Placusates. I have not been able to 

 procure the single European insect, Diestota Maijeti, 

 for which Rey founded his rameau, but I believe these 

 insects will prove to be really allied to the European 

 insect, though it is not probable they will be really con- 

 generic therewith. Although these Hawaiian insects 

 differ inter se in the structure of the intercoxal parts, 

 it Avould be impossible for me to treat them at present 

 as forming more than one genus, without making three 

 or four genera for them, a course which would be inad- 

 visable, as I have not at present specimens enough for 

 examination and comparison of the details of their struc- 

 ture.
