Head evidently smaller than thorax, rounded behind, yet broader there 

 than the thoracic apex; basal fossae indistinct, the broad median depres- 

 sion extends forwards between the prominent antennal tubercles; the 

 sculpture indefinite, consisting apparently of small granules with a minute 

 puncture in each. Eyes moderately large and prominent, with coarse 

 facets. Thorax suboviform, of about equal length and breadth, rather 

 wider before the middle than elsewhere, rounded there, a good deal 

 narrowed anteriorly ; the mesial longitudinal sulcus is well marked, and 

 ends in the basal fossa, which is joined to the elongate fovea at each 

 side by distinct grooves; its. sculpture is like that of the head. Elytra 

 a third longer than thorax, rather broader than it is at the base, with 

 rounded shoulders; apices slightly oblique towards the suture, with 

 minute distant sculpture; sutural striae deep, intrahumeral impressions 

 short, each elytron tripunctate at the base, the punctures, however, are in 

 the striae. Hind-body shorter than the elytra, its basal three segments 

 nearly equal, the 1st with a deep transverse basal impression, with cari- 

 nate sides, the 2nd with a similar but more linear impression. 



Legs elongate; anterior femora thicker than the others; tibiae un- 

 armed; all moderately arched outwardly, the front pair with more con- 

 spicuous pubescence near the extremity. 



Antennae stout, bearing rather elongate pubescence; their 2nd joint 

 almost oval, as thick and long as the uncovered portion of the basal; 

 3rd nearly as long as broad, bead-like; joints 4—6 transverse, differing 

 but little; 7th and 8th abruptly broader, unsymmetrical, thinner at the 

 inner than at the outer sides; 9th and 10th transverse, still more en- 

 larged, but not double the breadth of the preceding pair, both broad at 

 the base but much narrowed in front; 11th conical, as broad as the 10th, 

 but not as long as the 9th and 10th combined; at its base, on the inside, 

 there is an obtuse tubercle. 



There is no necessity for comparison with other species, as the very 

 remarkable antennae are abundantly distinctive

3206. Euplectopsis eruensis sp. nov. 



Elongate, moderately convex, nitid; rufous; legs and antennae paler, 

 tarsi flavescent ; pubescence greyish-yellow, suberect. 



Head evidently smaller than thorax, nearly straight behind the small 

 eyes, a little uneven and slightly asperate, but without well-marked foveae 

 or punctures. Thorax suboviform, a little broader just before the middle 

 than it is elsewhere, rather longer than broad, indistinctly punctate; 

 median sulcus narrow, sharply marked, extending into and dividing the 

 basal fossa and becoming cariniform at the base; lateral foveae large, 

 each with a slight groove uniting it to the basal fossa. Elytra subquad- 

 rate, not exceeding the thorax in length, curvedly narrowed near the 

 base; sutural striae deep and foveiform at the base, intrahumeral im- 

 pressions also deep at the base but shallow towards the middle. Hind- 

 body as long as the elytra, the basal two segments horizontal, 3rd slightly 

 deflexed and shorter than 2nd, the 1st visible segment medially flattened 

 towards its base, and with a pair of curved carinae there. 



Legs moderately stout, anterior femora thicker than the others, all the 

 tibiae slightly dilated and curved below the middle.
