240 FAUNA HAWAIIENSIS 



(ill) Froterhinus hypotretus, sp. nov. 



Sordide niger, vel rufescens, elytris nigro-maculatis. Antennae minus fortiter 

 elongatae, crassiusculae. Oculi minus fortiter prominentes. Pronotum minus dense 

 squamosum, plerumque plus minusve evidenter 3- vel 4-impressum, impressione anteiiore 

 sat distincta. Elytra maculatim squamosa, macula albida humerali aliisque posteria'ibus 

 subrotundatis, sat distinctis, setisque erectis gracilibus albidis conspicue vestita, basi 

 leviter emarginata, humeris distinctis, sed parum productis. Abdominis segmentum 

 primum ventrale dense ac fortiter punctatum. Long. 2 '2 — 3 mm. 



Allied to the preceding species, but of wider form, and differing in colour, the 

 insect being redder. Also closely allied to F. vestitus of Oahu, some varieties of 

 F. angularis, &c., but certainly distinct from any of these. In fresh examples the 

 maculate arrangement of the squamosity of the elytra, and the numerous erect fine 

 setae, are very conspicuous. The elytra themselves are usually flattened or slightly 

 impressed along the suture, the condition of the humeral angles is very similar to that 

 seen in the same parts of F. vestitus. The lobes of the front tarsi are by no means 

 large. 



Hab. Hawaii. 



(112) Froterhinus desqiianiatns, sp. nov. 



Ferrugineus (elytris cum capite nonnunquam obscuratis sive nigro-rufis), elongatus, 

 parum squamosus. Antennae concolores, rufae, articulo secundo brevissimo. Prono- 

 tum parum latum vel subelongatum, parum profunda 3-impressum, subaequaliter nee 

 dense squamulosum, angulis posticis macula squamosa densiore signatis, lateribus 

 rotundatis. Elytra elongata, vix squamosa, satis erectis pallidis, minus elongatis, 

 sparsim sed conspicue vestita, dense fortiterque punctata, basi emarginata, humeris 

 acutis. Abdominis segmentum primum ventrale fortiter et distincte punctatum. ^ %. 

 Long, circiter 3 mm. 



On account of its elongate narrow form, ferruginous colour, and lack (at least for 

 the most part) of squamous covering, this species could only be compared with F. fer- 

 ruginetis, so far as the species of Hawaii are concerned. It is distinct at once from that 

 insect by the distinctly and strongly punctured basal segment of the hind-body beneath. 

 Extremely closely allied to F. detritus of Lanai, it may be distinguished from that 

 species by the more evenly rounded sides of the prothorax, which are not so strongly 

 and abruptly narrowed in front, and the puncturation of the elytra is apparently rather 

 less coarse. 



Hab. Hawaii, Kona (2000 — 3000 ft.) ; rare, 2 ^ and i $ only having been taken.
