208 Mr. D. Sliarp on some 



verse bnncl of pale hairs ; all tlie apical portion is chiefly 

 clothed by dark hairs, except that along the suture, and also 

 at the a])ical portion there are scanty, irregvilarly-distri- 

 buted pale hairs : there are no Avhite hairs at all on the 

 middle tarsi. 



A single male individual has been sent from Oahu as 

 No. lOO^'by Mr. Blackburn. 



These two species possess the three characters the com- 

 bination of which in a Ceravihycid vrai sylvain entitles 

 the possessor to enter, according to Lacordaire, his group 

 of Clijtides^ viz., antenna3 not surpassing the extremity of 

 the elytra, a laterally unarmed thorax, and a basal joint to 

 the hind tarsus longer than the two following together. 

 I give below their characters. 



Ligula membranous, mandibles short, terminal joints 

 of palpi very little dilated, but obliquely truncate at tip. 

 Front of head vertical, nearly at right angles with the 

 extremely short vertex ; antennal tubers not very distant, 

 rather elevated, with a deep depression and channel 

 between them. Antennae rather short and slender, differ- 

 ing but little in the two sexes, not extending to the 

 extremity of the elytra; 1st joint moderately long and 

 stout; 2nd, not so extremely abbreviate as is usual in 

 the family, but distinctly shorter than the 1 0th joint ; 

 3rd, equal in length to the 1 st, but only half as thick ; 

 4th, nearly equal to 3rd ; 4th — 7th, each a little shorter than 

 its predecessor; 8th, 9th and 10th, subequal and distinctly 

 shorter than the other ones; 11th, a little longer than 

 10th. Eyes finely facetted, rather prominent, but not 

 large, of an excessively short kidney form, departing in 

 fact but little from the circular form, except that there 

 is a well-marked notch filled with pale pubescence on 

 their upper and inner edge contiguous with the insertion 

 of the antenna. Front coxas globular but distinctly 

 exserted, so as to project a good deal beyond the pro- 

 sternal process, their cavities very open behind, but Avith 

 only a very small prolongation externally; prosternal 

 pi'ocess not reaching quite so far back as the hind part 

 of the coxa3, and therefore without the least Avidening 

 at its apex. Mesosternum rather large, very similar 

 indeed to that of Cerambyx licintus, Linn., its posterior 

 prolongation having but little difference of plane or level 

 from the front part ; its articulation Avith the middle 

 of the metasternimi imperfect; middle coxae rather large, 

 globose, their cavities externally Avith a large opening.
