Chitalia. They also differ in the more widely separated 

 middle coxae, with the broadly arcuato-truncate mesoster- 

 nal process fitting closely against the metasternal projec- 

 tion, on the same level, without depression of any kind 

 and without an intervening isthmus. The basal joint of the 

 hind tarsi is very slender, fully as long as the next three 

 combined, the latter decreasing slowly and regularly in length. 

 In some features Leptagria recalls the European genus 

 Melagria, but may be readily distinguished by the characters 

 of the table. We know at present but two species which may 

 be described as follows : — 



Form slender, subparallel, moderately convex, polished, pale brownish- 

 testaceous, the antennae distally, head and an apical abdominal cloud 

 darker, piceous; pubescence inconspicuous; head wider than long, 

 parallel, the base broadly arcuato-truncate with the angles rounded; 

 eyes well developed, rather prominent, the punctures very minute and 

 sparse; antennae extending nearly to the middle of the elytra, moder- 

 ately incrassate distally, the second joint much longer than the third, 

 seven to nine distinctly transverse, equal in length, the tenth decidedly 

 longer but still obviously wider than long, the eleventh short, obtuse; 

 prothorax small, somewhat wider than long, evidently narrower than 

 the head, the sides evenly rounded anteriorly, thence strongly converg- 

 ing but scarcely at all sinuate to the base, which is nearly three -fourths 

 as wide as the disk; sulcus ending abruptly near apex and base, the 

 surface strongly convex, very minutely, sparsely and obsoletely punct- 

 ulate; scutellar granules parted narrowly along the middle; elytra 

 nearly four-fifths wider and more than a third longer than the pro- 

 thorax, the sides evidently diverging from the base, rather strongly 

 arcuate posteriorly, extremely minutely and somewhat sparsely punctu- 

 late throughout, not impressed on the suture basally; abdomen sub- 

 parallel, rather wide, with nearly straight sides, posteriorly fully as 

 •wide as the elytra, very minutely, not very closely punctulate, the first 

 impression with a few coarser but subobsolete punctures, the second 

 and third gradually narrower and feebler, impunctate ; legs very slender, 

 the hind tarsi slightly shorter than the tibiae. Length 1.65 mm,; 

 width 0.38 mm. Texas (Brownsville),— H. F. Wickham. 



perexilis n. sp. 



Form and coloration nearly similar throughout, slightly stouter, equally 

 shining, the head nearly similar; antennae almost similar but rather 

 stouter and more incrassate, the joints six to ten decidedly transverse, 

 the tenth obviously longer than the ninth, the eleventh ogival, not as 

 long as the two preceding together, second much longer than the third; 

 prothorax larger, somewhat wider than long, the sides more angularly 

 prominent before the middle, thence converging and broadly, feebly 

 sinuate to the base, the surface less convex but similarly sculptured,
