76 ON A COLLECTION FEOM MOUNT KORAIMA. 



TENEBRIONIDvE. 



Cyrtosoma montanum, sp. n. 



Oblonguni, nitidum ; capite, thorace femoribusque fere nigris ; elytris seneis, teauiter 

 striatis ; ore, autennis, tibiis tarsisque piceo-flavis. 



Long. 11, lat. 5| mill. 



Head finely and rather closely punctured. Antennae with the six terminal joints 

 gradually wider. Thorax finely but distinctly and rather closely punctured, with a very 

 slight, transverse impx-ession above the anterior angles and above the posterior angles ; the 

 sides with tAvo obtuse not very prominent angles. Scutellum pitchy. Elytra rather wider 

 than the thorax, one-quarter longer than broad, rather straight at the sides, obliquely 

 narrowed at the apex, finely striated, the striae indistinctly punctured, the interstices 

 scarcely convex on the back, but at the apex and at the sides they are slightly angularly 

 raised in the middle ; the fourth and fifth strise unite posteriorly about one-third from 

 the apex, the third and fifth unite nearer the apex, and the second and sixth within the 

 apical angle. The underside of the insect is for the most part pitchy red, shaded with 

 black on the metasternum and abdomen. 



LAMIIDiE. 

 Alcidion sexnotattjm, sp. n. 



Elongatum, angustum, fuscum, pube grisea vestitum ; thorace basi constricto ; ely tris 

 fasciis punctisque numerosis fuscis ornatis, singulo elytro ad apicem oblique 

 truncate, angulo saturali obtuso, angulo externo rectangulare ; antennis gracilibus, 

 corpore multo longioribus. d . 



Long. 11, lat. 4 mill. 



Compared with the majority of the species of this genus, this is very elongate and 

 narrow. The antennae are very long ; the basal joint is much narrowed at the base, 

 then quite straight and parallel to the apex ; the joints are tipped with black and have 

 some black pubescence, which forms a slight tuft at the apex of the third joint. The 

 thorax is short and transverse, lightly impressed on the disk, arcuately narrowed 

 anteriorly, slightly constricted at the base ; the middle of the disk and three or four 

 small spots at the sides are brown. The elytra have scarcely any trace of costae ; the 

 basal crest is well marked but not acute ; the basal area is brown, with two vague 

 oblique vittae of ashy pubescence marked with brown punctures ; at the middle there is 

 an irregular ashy fascia (descending at the suture) marked with brown punctures ; 

 behind this is a fascia formed by five elongate spots placed side by side, the sutural one 

 lower down than the others ; in the apical area there are six brown spots, three of which 

 are placed so as to make V I on the left elytron. 



The following species, not of very special interest, were found at an elevation of 

 3500 feet :—
