SOME ENDOMYCHID BEETLES — STROHECKER 389 



joints red ; joints 6 to 10 black ; joint 11 black, with its apical half red. 

 The lateral sulci of the pronotum are shallow but sharply impressed 

 and extend to the middle of the disk. Between these sulci and occu- 

 pying most of this area is a pair of large, quadrate, black spots, nar- 

 rowly separated from each other. On the elytra the basal third, 

 including the humeri, black; internally this black area is continued 

 as a narrow stripe along the suture, broadening a little on its apical 

 third, thence becoming evanescent. At the middle of each elytron there 

 is a large, rounded, black spot, laterally placed and behind this a 

 similar but considerably smaller spot. The entire upper surface is 

 clothed with a short, declivent, coppery pubescence. The puncturing 

 is everywhere fine and sparse except at the sides of the pronotum, 

 where it becomes a little denser and coarser. The front tibia bears a 

 broad, sharp tooth internally at its distal third. Another feature, 

 probably sexual, is a densely pubescent area of semicircular shape at 

 the middle of the posterior margin of the first abdominal segment. 

 Length 8' mm., width 4 mm.

Genus MILICHIUS Gemminger and Harold 

 MILICHIUS IMPRESSICOLLIS, new species 



General aspect of M. ampliatus (Gorham) . Ferruginous, the elytra 

 with aeneous sheen. Antennae stout, joints 3 and 4 subequal, twice as 

 long as broad; joints 5 to 7 little longer than broad; joint 8 quadrate; 

 joints 9 and 10 cylindrical, each equal in length to joint 3 but stouter; 

 joint 11 oval, three- fourths as long as 9 and 10 together and very little 

 wider. Joints 1 to 5 ferruginous; joints 6 to 8 and 11 black; 9 and 

 10 light yellow. Pronotum transverse, front angles produced and 

 acutely rounded, sides bisinuate and reflexed, forming a broad groove 

 within the margin, disk coarsely, irregularly punctured (as is the head 

 also), smoother along midline and with a deep, large impression on 

 each side. Basal foveae short, linear; basal sulcus fairly deep, close 

 to hind margin of pronotum. Elytra broader at base than pronotum, 

 thence slightly widened, somewhat tapering posteriorly. Umbone 

 elevated, subcarinate laterally. Disk of elytra very finely and sparsely 

 punctured, the area around the umbo and posterior to it coarsely and 

 confluently punctured. Prosternum broad, coarsely punctured. Under 

 surface, including bases of femora ferruginous ; apical half of femora 

 and proximal half of tibiae infuscate; distal half of tibiae and the 

 tarsi yellow. Length 3.75 mm. The yellow ninth and tenth antennal 

 joints and bifoveate pronotal disk are distinctive.
