that they are made up of the coalescence of several smaller tubercles. 

 Each main tubercle is covered by from four to six scales. 



In this, and the next species, the predominant type of scale on 

 abdomen is simple, but in most specimens a few plumose scales can 

 be detected on third, fourth, or fifth segments. In minor the per- 

 centage of simple scales is much higher — at least I have seen no 

 specimen of that species with as many plumose scales on abdomen 

 as are often present on the other two. 



MESAGROICUS HERRICKI Pierce 



Lepidocricus herricki Pierce, Journ. Econ. Ent., vol. 3, 1910, p. 362; Proc. 

 U. S. Nat. Mus., vol. 45, No. 1988, 1913, p. 420.— Blatchley and Leng,

 for two more species). — Dury, Bull. Brooklyn Ent. Soc, vol. 18, 1923, p. 27 

 (probably refers to the species described in this paper as minor). 



Twenty-two specimens (including three from the original type 

 series). Length, 4-6 mm.; width, 2-2.7 mm. Brown, the pale 

 markings, when present, as in the two preceding except that the 

 dorsum of elytra appears to be normally of a much darker and 

 unmottled brown. About half the specimens with a large pale spot 

 on third interval halfway down the declivity. Rostrum with a broad 

 and deep median sulcus. The pro thorax is narrower, compared to 

 elytral width, than in oMongus. Measurements of these parts give 

 the following average figures for six males and six females of each 

 species: Width of prothorax is to width of elytra as 22.5 is to 36 

 (male Jierriclci) ; as 27 is to 46 (female herricM) ; as 24 is to 36 (male 

 ohlongus); as 27 is to 41 (female ohlongus). Abdomen coarsely punc- 

 tate. Compared to ohlongus and minor, herricki shows the following 

 differences: Rostrum more deeply sulcate; eyes more prominent 

 (more prominent in male); antennae stouter, the second funicular 

 segment somewhat longer and in a few cases very nearly as long as 

 first; pronotal tubercles much more prominent and more sharply 

 defined; elytral setae longer; abdominal punctures larger; legs heavier, 

 the tibial denticulations coarser. 



The deep rostral sulcus, the prominent eyes and pronotal tubercles, 

 and the coarse abdominal punctation are the distinctive characters 

 of this species. 



Localities. — Mississippi (Easter, the type locality), (Waveland, 

 Soltau), (Picayune, W. M. Mingee) ; Alabama (Wadley, H. H. Smith) 

 (Bay Minette, Biological Survey, from stomach of meadow lark). 



MESAGROICUS PLUMOSUS, new species 



One specimen. Length, 5.2 mm. Width, 2.6 mm. Brown, with 

 pale vittae along sides of prothorax and on humeri. Rostrum as 

 long as head, flat above, median groove narrow, surface either side
