feebly curved, hind angles rectangular; surface rather finely and regularly 

 punctate, more densely and roughly on the sides. Elytra broadly not deeply 

 sulcate, the grooves with two rows of coarse, confluent punctures; intervals 

 feebly convex, sparsely punctate. Length 8.5-11 mm.

Serica cari]\ t x\ta sp. nov. 

 Oblong-oval, subdepressed. Piceous-brown, feebly 

 shining; antennas, legs and under surface reddish- 

 brown. Clypeus and front very densely and finely 

 punctate, the notch minute, not more than one-third 

 the' depth of that of vespertina ; frontal suture viewed 

 from the side, with a distinct transverse raised line 

 or carina ; front with a longitudinal carina connect- 

 ing that of suture with hind margin of head. Thorax 

 two-thirds wider than long sides nearly straight, feebly 

 curved on apical third, hind angles rectangular; disk 

 densely and finely punctate at middle and on sides, 

 more sparsely and coarsely near front and hind mar- 

 gins and in a space near front angles, a very small smooth area near the 

 middle. Elytra less deeply sulcate than in vespertina, the grooves broader, 

 each with two or three irregular rows of finer, more or less confluent punc- 

 tures. Meta sternum, hind coxal plates and first five segments of abdomen 

 coarsely and rather sparsely punctate ; sixth ventral segment smooth". Length 

 8-10 mm. (Fig. 372.) 



Described from eight specimens taken in Fountain, Marion, 

 Vigo, Crawford and Posey counties. April 9-October 6. Taken 

 from beneath bark of oak. Those taken on October 6 were in mud 

 or dirt cells beneath deeply buried logs on wooded hillside in Yigo 

 County, and were just emerging as imagoes. Probably confused 

 with vespertina in most collections, but readily distinguished by the 

 carinate suture of clypeus and close, irregular punctuation of tho- 

 rax. The color in all specimens at hand is uniform and not vari- 

 able as in vespertina or the next. 



1807 ( -). Serica intermixta sp. nov. 



Oblong, convex, smooth, shining. Dull brownish-yellow, sometimes 

 chestnut-brown or even black. Clypeus longer than in vespertina, the notch 

 smaller, one-half as deep ; surface finely and sparsely punctate ; front more 

 coarsely and sparsely punctate. Thorax more convex than in vespertina, 

 sides feebly curved, surface finely and rather sparsely but evenly punctate. 

 Elytra moderately deeply sulcate, the grooves each with two or three irregu- 

 lar rows of rounded, more or less confluent punctures ; intervals subcon- 

 vex, sparsely punctured, the punctures as large as those of the grooves. 

 Length 7.5-9.5 mm. 



Lake, Vigo, Marion, Lawrence and Jennings counties; frequent. 

 April 12-June 26. Occurs beneath bark. Specimens just emerg- 

 ing as imagoes were taken in Vigo County on April 12 and in Lake
