132 FAUNA HAWAIIENSIS 



strongly spinose, about four times as long as tarsi, third tarsal segment not shorter than 

 first and second together. 



$. Second segment of antennae somewhat evenly thickened ; vertex about as 

 wide as the eyes together. First genital segment three times as long as the ultimate 

 abdominal ; forceps sickle-shaped, ribbon-like. 



%. Antennae slender, vertex one-half wider than the two eyes together. Ultimate 

 abdominal segment above roundly emarginate, beneath widely biemarginate. 



Long. 2,'Z — 3'5 mm- ; lat. \'2 mm. 



var. a. The sanguineous replaced by luteous. 



Hab. Of the type and var. a I have seen 17 examples from Hawaii, Kona, 

 4000 ft. (July, August) ; Kilauea (August). — -Maui, Haleakala, 5000 ft. (October). — 

 Kauai, Halemanu, 4000 ft. (May). 



var. /3. pcliduoptents, var. nov. 



Blackish-brown, cuneus (more or less), femora (more or less), apical half of head, 

 lateral margins (widely) of pronotum, and two spots at base of pronotum — yellowish. 



Hab. Three examples from Hawaii, Hualalai, 5000 ft. (August). The forceps is 

 identical with that of the type. The tuberculate spots are visible in an oblique light. 



P. sharpianus, which I dedicate with pleasure to my friend Dr David Sharp, from 

 whom I have received many entomological kindnesses, is nearest allied to P. atoi7tosus 

 Reuter. In some respects it is near Plagiognathus (sens, lat.) but the granulate eyes, 

 and the long third segment of the posterior tarsi as well as the general facies, include 

 it in Psallits.
