Imago (59: 7). Head very large, heavily clothed above with not very long hairs 

 mostly arranged ill transverse inasse.s ; outside of the antennae there is a thin, com- 

 pressed, spreading tuft of arcuate bristles, inclined a little forward, and passing less 

 than one-tliird way over the eye. Front protuberant, extending, excepting at its upper 

 extremity, some distance be.voud the front of the eyes, rather tumid, most so just below 

 the midillc when viewed laterally, and at tlie middle viewed from above, regularly 

 and cousiderahly arcuate from side to side ; a transverse, rather sharp and prominent 

 ridge, which turns a little upward at its extremities and terminates at some distance 

 below the inner edges of the antennae, the whole piece about two and one-fourth times 

 as broad as long, the front border broadly rounded, a little straightened in the middle, 

 terminating at the outer edges of the antemiae; it is separated from the vertex by a 

 straight, slightly impressed line connecting the middle of the antennae. Vertex only 

 slightly arcuate longitudinally, scarcely reaching tlie level of the eyes, separated from the 

 occiput, which is sulcate in the middle longitudinally, by a slightly impressed, regular, 

 brace-shaped line. Eyes pretty large, pretty full, nearly circular, naked. Antennae 

 inserted with their hinder edge scarcely behind the middle of the summit, separated 

 from each other by scarcely three times the width of the basal joints, the whole an- 

 tenna somewhat shorter than the abdomen, consisting of thirty -six joints, of which 

 seventeen or eighteen form the club, which is either about one-third the length of the 

 stalk, the crook consisting of three minute joints rapidly tapering to a point, forming 

 altogether an insignificant portion, scarcely longer than l)road, and about one-third as 

 long as the breadth of the club ; the latter, exclusive of the crook, is stout, oval, a little 

 compressed, scarcely four times as long as broad, broadly rounded at tip, tapering at 

 base, largest scarcely beyond the middle >vheu viewed laterally, in the middle of the 

 apical half when viewed from above ( J ) ; or, about one-fourth the length of the stalk, 

 the crook consisting of four joints, but in intimate continuation of the narrowing 

 apical joints of the club proper, the last nine joints of the whole tapering regularly 

 and rather rapidly to a point; this portion being nearly twice as long asbroad, while 

 theotlier extremity of the club tapers more gradually and the whole club is largest in 

 the midille. whether viewed laterally or from aliove, and is five times as long as broad 

 ( $ ) ; middle joints of the stalk three times as long as broad, the third from the basr of 

 antennae four times as long as broad. Palpi rather short and very stout, flattened in 

 front a little obliquely, nearly or quite twice as long as the diameter of the eye, clothed 

 very compactly with a very heavy mass of not very long scales, beyond which the ter- 

 minal joint, clothed pretty heavily but only with recumbent scales, is scarcely visible; 

 basal joint buUate, greatly expanded at tip, with a tumid extension on the inner side 

 fully as broad as long; middle joint large, bullate, broad, obovate, laterally consider- 

 ably arcuate, twice as long as broad, scarcely broader than the basal joint, somewhat 

 larger than the diameter of the eye, equally and l)roadly rounded at either end ; ap'cal 

 joint seated a little outside the middle of the anterior border of the extremity of the 

 middle joint, nearly cylindrical but slightly largest in the middle, witli both cuds 

 bluntly rounded, straight, its length about three and a half times greater than its width 

 and about three-fourths the width of the middle joint. 



Prothoracic lobes pretty large, appressed. laminate; viewed from the front they are 



*av9os. (lao-TTJp, flower seeker.
