NO. 1143. COLEOFTERA OF THE GALAFAGOS ISLANDS— LIXELL. 253 



SCARITES GALAPAGOENSIS, new species. 



Elongate, i^arallel, couvex, sbining black, apterous. Mentuin nearly 

 twice broader than long, broadly concave, smootli, acutely carinate at 

 middle, with a round fovea at base each side of the carina; the lobes 

 strongly rounded at the sides with a fine obtuse subiuarginal carina; 

 the tooth broad at base, abruptly narrowed and acute at apex, longer 

 than the lobes, the margins carinate. Maxillae incurved at apex and 

 acutely mucronate. Mandibles nearly as long as the head, arcuate 

 and acute at apex, bicarinate above, scarcely striate. Antennae piceo- 

 rufous, reaching to the hind angles of the thorax, the basal Joint a 

 little longer than the following three together, the second to fourth 

 obconical, decreasing in length, the fifth to tenth broader, compressed, 

 densely rufopubescent, slightly longer than broad; the terminal joint 

 oval, comjiressed. Parageuae broad, concave, smooth, emarginate and 

 dentate at apex, the inner margin rounded, not carinate. Eyes promi- 

 nent, truncate behind, and inclosed by the globose tem2)ora. Head 

 smooth, deeply bisulcate in front. Epistoma slightly striate toward 

 the sides, bideutate and emarginate at middle, with two small tuber- 

 cles at the emargination; the lateral margin in front of the eyes 

 rounded and less prominent than the eye. Labrum subequally triden- 

 tate with three coarse punctures, the median puncture bisetose, the 

 lateral ones unisetose. Thorax in front scarcely wider than the head, 

 narrowed and feebly rounded to the hind angles, nearly twice broader 

 than long; disk convex, smooth, the median and anterior transverse 

 lines distinct; anterior margin finely striate; posterior angles dis- 

 tinctly dentate; base pedunculate at middle, the oblique sides being 

 distinctly sinuate; a rounded fovea at the base each side of the pedun- 

 cle. Elytra as long as head and thorax including the mandibles, nar- 

 rower than the thorax, slightly dilated at middle and strongly rounded 

 to apex: humeri strongly dentate; disk couvex, deeply striate, striae 

 impunctate; intervals smooth, obtusely subcarinate, the third with one 

 puncture toward apex and the usual apical puncture; basal margin 

 and the ninth interval finely granulate, the latter with a series of punc- 

 turcH. Ventral surface smooth; the episterua of metathorax one-third 

 longer than broad. Ventral segments without imj)ressed basal line, 

 the subterminal ones each with two inmctures at middle, the terminal 

 with four i^unctures at the margin; the last two segments, with the 

 lateral margin and a connected spot, red, translucent. Legs moderately 

 stout; the anterior tibiae prolonged at aijex, tridentate in front, the 

 upper tooth very small, the terminal one very long and slender, cur- 

 vate, reaching to the third tarsal joint; no trace of denticles above the 

 third tooth. Middle tibiae with one spine near apex and with a row of 

 denticles, increasing in size from the knee downward. Posterior 

 tibiae slender, without dense fimbriae. Tarsi slender. Claws long, 

 arcuate. Length, 27 mm.; width, 9 mm.
