between the first and second costae, a third in a line with the 

 second near the apex, and a few others of smaller size in other 

 positions. The under side of the body is of a dull black and 

 punctate, with a large shallow fovea on the side of each of the 

 abdominal segments. 



This species seems to approach the L. cirrosa Pasc. It is, 

 however, much less variegated, and the fascicles are much shorter 

 and less numerous.

Length If lines. 

 Brown, flat and opaque. Head punctate, with a shallow de- 

 pression on each side in front of the eyes. Thorax punctate, and 

 nearly square with the anterior angles advanced, the posterior 

 square and acute, the sides margined and finely serrated, with 

 two costa3 on each side curved towards the apex, and joining to- 

 gether on the apical margin, and two others short and ill-defined 

 at the base and near the centre. Elytra scarcely wider than the 

 thorax, parallel-sided, rounded at the apex, punctato-striate, — 

 the altei^nate interstices three in number, elevated into large 

 costiB, — and marked each with two indistinct patches of deep dull 

 red, one near' the humeral angle, extending nearly diagonally to 

 the middle of the elytra and towards the suture, the other an 

 elongate spot, is situated between the middle and the apex.

 Length 5 lines. 

 Dark brown, subopaque. Head punctate, with a shallow 

 round impression on the anterior margin. Thorax elongate, 

 cordiform, strongly but not densely punctate, and sinuate at the 

 base, with the posterior angles acutely pointed at the termination 

 of a short rather oblique costa, and with the thoracic canal deep 

 at the base, getting shallower towards the interrupted portion 

 which is very short and shallow, and terminating at about one 

 fourth of the length from the apical border. Elytra striated and
