and one t has these organs evidently more elongate and more slender than those of the 

 other examples of either sex. The general resemblance in colour and clothing between 

 the few individuals secured is very great. It is one of the darkest species, and of rather 

 large size. 



Hab. Hawaii (3000 — 4000 ft.) ; rare, but widely distributed. Five examples only 

 were secured in the Kona and Kau districts.

A somewhat distinct-looking species, of dark colour and moderate size. The 

 antennae are fairly long and quite slender, the club very well-marked, and consisting of 

 three joints. The eyes and tarsal lobes are both large. The elytra are not much 

 covered with squamosity, this being chiefly noticeable along the two by no means 

 strongly marked longitudinal ridges. The suture is also a little raised. The humeral 

 angles are produced and very acute, and the basal tubercles well marked, as also is the 

 puncturation. The colour of the insect is black or obscure pitchy-black, the lobes of 

 the tarsi and antennae sometimes paler. Rostrum of the female rugulose, dull, or 

 hardly shining.

Rufescens, capite, thorace, femoribusque, saepe obscurioribus, elytris plus minusve 

 nigro-maculatis. Antennae minus fortiter elongatae, articulis saepe crassiusculis, non- 

 nunquam sat gracilibus. Oculi magnitudine mediocres, prominuli. Pronotum sat 

 fortiter 3-impressum, aequaliter subferrugineo-squamosum. Elytra rufa, nigro-maculata, 

 subseriatim fortiter punctata, minus dense squamosa, albidis duabus postice maculis 

 ornata, setisque albis elongatis rarius conspersa, fere aequaliter convexa, basi scutellum
