coxal plate very short, moderately ^vide, but not attaining tlie sides. Legs 

 moderately stout, last joint of tarsus as long as the four preceding taken 

 together. 



This genus closely resembles Trinodes, but the latter has the prosternum 

 prolonged sub-acutely behind, entirely dividing the mesosternum, and 

 the anlennal cavities are wanting. 



A. hispidus Mels. Sub-oval, convex, black, covered with sparse, very 

 long, erect, brown hairs. Elytra brown or black. Head sparsely pubes- 

 ceat. Antennae ll-jointed, testaceous, club 3-jointed, darker. Thorax 

 sparsely punctured and pubescent. Scutellum naked. Elytra black or 

 rufous, coarsel}', moderate]}^ sparsely punctate, pubescence sparse, ver}-- 

 long. Bodj' beneath light brown, pubescent. Abdomen coarsely punctate, 

 pubescence more dense. Length .05 inch ; 1.5 mm. (Figs. 74, 77.) 



Male. Antennae terminated by a 3-jointed club, of which the joints 

 1-2 are small, 3 half as long as the entire antenna. (Fig. 75.) 



Female. Antennae bearing a 3-jointed club, the last joint of which is 

 equal to the two precetling taken together. (Fig. 7G.) 



In addition to the anatomical characters already given, we may recog- 

 nize the insect by the small size and long erect pubescence. 



Occurs in the Middle and Southern States. 



ORPHILUS Erichs. 



Head with small but distinct ocellus. Eyes moderately prominent, 

 moderately coarsely granulated, emarginate in front. Antennae ll-jointed, 

 bearing a 3-jointed club. Thorax very convex, nearly as long as wide at 

 base, apex only one fourth as wide as the base, which is bisinuate, sides 

 arcuate, lateral margins nearly straight, only the posterior half can be 

 seen from above. Hind angles moderately prominent. Scutellum dis- 

 tinct. Sides of elytra nearly parallel, antennal cavities not well defined, 

 confined to the anterior half of spaces between prosternum and side mar- 

 gins, which space is marked just behind middle, with a deep pit to receive 

 the knee of the anterior leg, behind which is the usual transverse fossa for 

 the middle leg. (Fig. 82.) Prosternum small, declivous, produced behind 

 but not passing the anterior coxae, which are very large and approximated. 

 Mouth parts and prosternum covered by the anterior legs. Mesosternum 

 large, as broad as long, rounded in front, widely separating the mesocoxae. 

 (Fig. 80.) Hind coxae short and wide, reaching the sides of the body. 

 Coxal plates also wide, covering the anterior portion of the femur for its 

 entire length. (Fig. 81.) Femora very stout, attaining the sides, punc- 

 tured, channeled beneath for the tibiae, anterior libiie very broad and flat, 

 with a groove on the anterior surface to receive the tarsus. (Figs. 83, 84.) 

 The middle and posterior tibiae are more slender. Tarsis moderately 

 slender, last joint equaling the four preceding added together. 



The characters upon wiiich to rely for a proper appreciation of this genus 

 are, the insignificant prosternum ; large, entire mesosternum ; the largo
