TilK LAMELLICORX BEETLES. 948 ter in the form of a louuaed lobe; base rather acutely lobed at middle; disk with four elongate tubercles along the b;is:il margin, the outer one each side with a smaller one in front; the median pair each with a Y-shaped ridge in front, these ridges forming the sides of a median groove. Elytra with rows of moderately elevated, oblong, tubercles, tomentose at summit; be- tween the rows of large tubercles is a row of smaller ones, also tomentose at top, and on each side of the smaller tubercles is a row of rounded granu- lar elevaticins; the surface between all tubercles and elevations, smooth. Length 15-1S mm. Lake County: rare. Sppteniber 3. I liave seen but a single specimen, taken In- J. D. Hood on the beach of Lake ilichigan, near Pine. Tt occurs on the sandy shores of lakes and rivers and is said to be abundant in the (julf States. The rows of three different sizes of tubercles on the elytra readily distinguish this from our other large species. 177S (5614). MO^ACH^s Herbst., Kafer, III. 17S0, 25 More oblong and less robust than scahrosus. Dark brown or fus- cous. Thorax with sides subangu- late in front of notch near hind an- gles ; basal margin deeply sinuate near the angles; tubercles as in scabrosus. Elytra each with five rows of rounded or oval tubercles, tomentose at tip, rather distantly placed one from another, those of one row alternating with those of the next; the spaces between the tuber- cles finely and sparsely granulate, one of the tubercles of third row on apical fourth of elytra is much enlarged, the corresponding one in the fourth and fifth row also enlarged, but smaller than that of the third. Length 13-16 mm. (Fig. 368.). Fig. 36S. a, larva; b, pupa; c, beetle; d, e, f, lep, cervical plate and maxilla of lan-a. (After Ei
