light scattered scales, these scales thinner than the ones on occiput ; the 

 punctures not so coarse as in denticollis or movallus. Antennae ex- 

 tending a little below the humeri, the five distal joints heavier and 

 darker brown. Prothorax nearly as broad as elytra and considerably 

 wider than long, with a o-toothed margin and tooth at basal and apical 

 angles; depressed along basal margin especially over the scutellum, 

 convex otherwise, a flat area over the head and conspicuously 

 pinched in behind the eyes ; punctation rather deep and confluent and 

 in longitudinal lines; scales dense, closely appressed and concealing 

 punctation. Elytra about twice as long as the prothorax, broad, con- 

 vex, with sharp little humeri and no basal callosity, the rows of punc- 

 tures not so closely placed as in denticollis ; scales rather broad and 

 closely appressed. Body beneath shining under less dense scaliness, 

 abdomen with finer scales, first segment moderately densely but not 

 very coarsely punctate ; a round depression at tip of female abdomen 

 and a more triangular one on male. Legs short and heavy, a trace of 

 a blunt tooth on hind femora and a sharp tooth on inner side of an- 

 terior tibiae. Length 3.2 to 5.5 mm. ; width 1.8 to 2.7 mm. 



Type and paratypes. — Type male and two female paratypes, 

 U.S.N.M. No. 59026. 



Type locality. — Jacksonville, Fla., collection of Ashmead. 



Other localities. — Florida: Archer, Brooksville (P. J. Darlington), 

 Dunedin (W. S. Blatchley), Homestead (R. H. Beamer) ; Georgia: 

 Baconton; South Carolina: Florence (R. H. Beamer) ; North Caro- 

 lina: Southern Pines; Virginia: Virginia Beach (A. P. Morse); 

 Alabama: Delchamps, Mobile (H. Soltau) ; Mississippi: Hancock 

 County (H. Soltau) ; Louisiana: Covington (H. Soltau). 



Remarks. — This is one of the most distinct of North American spe- 

 cies of Myochrous. The broad heavy thorax, which is a third as long 

 as the beetle, with its peculiar pinched-in depression behind the eyes, is 

 very striking. The legs are short, the scales are coarser than in 

 denticollis, and the elytral punctures are less dense.

 Myochrous movallus P. H. Johnson, Can. Ent., vol. 63, p. 148, 1931. 



From 4 to 5 mm. in length, elongate oblong, dark reddish brown, 

 densely covered with brown and white scales, often giving the beetles 

 a speckled appearance ; thorax nearly as long as wide, inconspicuously 

 3-toothed, decidedly convex and with a depression along the base and 

 suggestion of a median depressed line ; elytra also rather convex. 



Head densely covered with brown and white, closely appressed 

 scales forming a brown, irregularly star-shaped pattern on front, 

 a median depression down front and a somewhat indistinct ridge on 

 either side of the occiput extending down to above the eyes ; surface
