 Dull brownish-yellow, shining, very finely pubescent. Head slightly 



wider than long, finely but distinctly punctate. Antennse reaching middle 

 of thorax, joints 3 to 8 bead-like, very small, ninth and tenth wider but not 

 longer, eleventh very large, ovate-conical. Thorax as wide as long, widest 

 just in front of middle, disk with a deep transverse sulcus at base, connect- 

 ing a small fovea each side. Elytra each with two basal fovea?, the discal 

 line reaching middle. Length .8 mm. (Fig. 152, c.) 



Putnam County; rare. April 22.* 



XIX. Melba Casey. 1897. (A name.) 



Head smaller; last antenna! joint large, cone-shaped ; occiput in 

 our species with a median impression; first dorsal not elongate;

 and unites with a small fovea each side. Elytra strongly convex, the discal 

 groove limited to basal fourth. Length 1 mm. (Fig. 152, d.) 



Starke and Monroe connties ; rare. May 8-May 18. 



M. thoracica Brend., dull yellow, pubescence fine, abundant, 

 length .9 mm., was described from Illinois and Iowa, and is said to 

 occur on moist, rotten wood, with ants, and to be abundant in June. 



G29 ( ). Melba maja Brend., Trans. Amer. Ent. Soc, XIX, 1892, 167.
