ANANCA. 
Ananca collaris, n. sp.—Rufo-testacea, capite supra elytrisque nigro-plum- 
beis, antennis pectore abdomineque fuscis; elytris opacis, minus argute sculp- 
turatis, absque lineis elevatis. Long. 8-11 m.m. 
Maxillary palpi, with their terminal joint slightly dilated internally; antennz 
elongate, but not so long as the insect; thorax bright yellow, narrowed behind, 
and a good deal rounded at the sides in front, rather closely but indistinctly pune- 
tured, its surface slightly uneven; elytra of a dull leaden black, their surface 
sculptured rather closely, the sculpture not consisting of impressed punctures, 
without raised lines, though on careful inspection traces may be seen of the rudi- 
ments of two such lines, that near the suture being the more distinct. 
Mr. Blackburn has sent me, as he believes, the sexes of this species, but they 
do not differ except that the antenne are slightly longer in one. The colour of 
the metasternum and tarsi is a little variable, these parts being sometimes fuscous, 
sometimes yellow. 
Single individuals of this species are occasionally found about Honolulu. 
Fam. AGLYCYDERID ZA. 
PROTERHINUS, 
Proterhinus linearis, n. sp.—Angustus ; subparallelus ; crasse confuse punctatus; 
nigro-fuscus, antennarum basi, pedibus, prothorace et elytrorum basi rufis; pro- 
thorace elongato, lateribus leviter rotundatis; elytris subparallelis, humeris 
obscuris. Long. 13 m.m.; lat. 2 m.m. 
This very pretty little insect resembles P. longulus, Sh., in shape, but is even 
narrower and more parallel. It is quite distinct from everything else known to 
me. he basal two joints of the antenne are rather large, the second especially 
being longer than is usual in the genus, and the remaining joints are stout. My 
specimen is somewhat abraded, but I can discover some traces of short setz on the 
elytra. 
A single female example occurred on Kauai, but the exact particulars of the capture have been lost. 
TBs 
Proterhinus scutatus, n. sp.—Angustulus; rufescens, marginibus lateralibus 
plus minusve nigricantibus; obscure aureopilosus; setis erectis sparsim nec con- 
spicue vestitus ; fortiter punctatus; prothorace fortius rotundato; elytrorum parte 
anteriore angustata ; humeris fortiter productis.. Long. 24-33 m.m.
