NEODECUSA, new genus 



Li facies exactly like Leucocras pedum Kraatz but at once distin- 

 guished by the 10-segmented antennae and the short narrow tongue 

 which is slightly longer tlian broad with parallel sides and rounded 

 apex, the right mandible with only a single small tooth, the left 

 edentate, in all other respects similar to that genus. From Decusa 

 Casey it differs in the longer first segment of the posterior tarsus, 

 which is as long as the second, third, and fourth together and the 

 fifth much shorter than the first as in T^eucocraspedum. The struc- 

 ture of the mouth parts in Decusa is unknown. 



145. NEODECUSA FORMOSAE, new species 



Moderately shining, head, thorax, and abdomen black or pitchy, 

 elytra pitchy brown. Antennae and legs reddish yellow. In build 

 and color resembling Leucocraspedtim scorjno Blackburn but slightlj'^ 

 smaller, with longer antennae, the penultimate segments not trans- 

 verse, the terminal segment longer, the puncturation of the head, 

 thorax, and abdomen scarcely differs in the two species but that of 

 the elytra distinctly finer. Antennae with first and second seg- 

 ments of equal length, the third segment a little shorter and more 

 slender than second, fourth as long as broad, fifth as long as fourth 

 but stouter, sixth to ninth as long as broad, gradually increasing 

 in size, tenth in male as long as the five preceding together, in female 

 as long as the three preceding together. Male, sixth sternite with 

 feeble arcuate emargination. Length, 1.75 — 2 mm.
