f)'<))i) Kiihi in y.JV. India. 15 



setiferoiis-crenated, strongly but obtusely dilated in the middle. Elytra 

 rather finely and closely subrugosely punctured, with obsolete and punctured 

 costse. Pygidium elongate, slightly convex, very coarsely and rather sparsely 

 punctured and wrinkled. The tooth of the claws is near the apex, and 

 strongly curved ; the base, also, has a broad tooth. Antennae with joints 

 3 — 5, nearly equal 6 — 7, short, and conically produced. Terminal ventral 

 segment convex, polished, with the apex (and apical part) of the penultimate 

 segment coarsely punctured and tawny-setose. Long. 12 — 16 millim. 



Belongs to Division I. of the genus, as defined in Biol, Centr.- 

 Amer. Col. ii. 2, p. 186, which is rich in Central-American 

 species. 



Lachnosterna batillaria, n. sp. 



Tawny-red, glabrous above ; breast and base of the legs densely clothed 

 with long, silky pile. Clypeus moderately long, quadrate, with the angles 

 rounded and anterior edge straight, rather deeply concave, shovel-shaped ; 

 forehead sloping, plane, both annulate-punctate, with the central parts 

 smooth ; occiput without transverse plica, more densely and finely punctured. 

 Thorax with regularly rounded sides, and very obtuse hind angles ; margin 

 crenulate, surface rather sparsely and finely annulate-punctate, with a 

 smooth space on the disk. Elytra more densely punctured, towards the 

 suture rugulose, a broad sutural and two similar discoidal costae slightly 

 elevated, smoother than the rest of the surface, and limited by striae ; some 

 of the punctures, especially towards the sides and apex, have a short grey hair. 

 Pygidium strongly convex in the middle, annulate-punctulate, glabrous. 

 Ventral surface nearly plane, sutures deeply impressed, except in the 

 middle, where they are, as usual, obsolete ; middle of each segment, from 

 side to side, punctulated, terminal segment entire, simple. Claws long, with 

 the tooth short and acute near the base, and the basal part dilated. Anterior 

 tibite bidentate, the third (upper) tooth scarcely indicated. Antennae 10-jointed, 

 normal ; the club slender, and equal in length to joints 2 — 7, taken together. 

 Long. 18 millim. 



Two examples ; judging from the absence of sexual modifi- 

 cations in the ventral segments, — females. The legs and tarsi 

 are, however, rather long and slender, as is usual in the male of 

 this and the allied genera. The species has the facies of a 

 Rhizotrogus. 



Lachnosterna batillina, n. sp. 



Oblong, narrow, reddish-tawny, clothed with short hairs, but shining. 

 Clypeus short, subquadrate, a little narrowed anteriorly, concave, the fore 

 margin slightly sinuated and more elevated in the middle, very sparingly 

 punctured ; forehead convex, and more strongly annulate-punctured. Thorax 

 with moderately rounded crenulated sides, and obtuse hind angles. Elytra 

 closely punctulate, the lightly indicated costae scarcely smoother than the 

 rest of the surface. Pygidium scarcely convex, rather closely beset with 

 setiferous annular punctures. Abdomen punctate-pubescent throughout, 

 convex in the middle, apical segment simple. Claws as in L. batillaria, long, 

 dilated at the base within, and sharply toothed at the end of the dilatation. 

 Antennae as in L. batillaria. Anterior tibiae tridentate. Long. 11 millim. 



Very closely allied to L. hatillaria. Two specimens, appa- 

 rently females. 



Lachnosterna gradatifrons, n. sp. 



?. Slenderly oblung, a little rounded and dilated behind, above glossy 

 black, glabrous beneath, and legs chestnut-brown ; antennae and palpi paler ;
