230 MB. M. JACOBY ON THYTOPHAGOUS COLEOPXEEA [Mar. 6, 



Lefevrea abdominalis Jac. 



Of this species described by myself (Proc. Zool. Soc. 1897, 

 p. 529) both sexes have now been sent by Mr. Marshall, taken by 

 him " in cop." They prove that the male is of totally different 

 coloration to the other sex and of smaller size, but whether this 

 is always the case I have not enough material before me to judge 

 from. I give here the description of the male insect : — 



Blackish ameous, the basal joints of the antennas and the legs 

 more or less fulvous : thorax strongly and somewhat closely punc- 

 tured ; elytra finely punctate- striate anteriorly only, greenish- 

 aeneous ; a humeral spot of semitriangular shape, flavous. 



Length 2 millim. 



In comparing the description of the typical form, the female, it 

 will he seen that the latter is larger, devoid of the elytral humeral 

 spots, and that the abdomen is fulvous : these differences are great 

 and peculiar, but there is certainly no difference in the sculpturing 

 between the two sexes, nor in the structure of the antenna? ; and if, 

 as I remarked above, the differences between the two sexes are 

 constant, it proves again how important it is to know the sexes in 

 descriptive entomology before one can judge a species with certainty. 



Lefevkea hiesuta, sp. n. 



Black, the antennas and legs pale fulvous ; thorax strongly 

 punctured and pubescent ; elytra more finely punctured in rows, 

 pubescent, flavous, the sutural and lateral margins and a spot near 

 the middle greenish black. 



Length 3 millim. 



Head blackish, with an aeneous tint, sparingly punctured and 

 pubescent, the clypeus not separated from the face, the labrum and 

 palpi fulvous ; antennas entirely flavous or fulvous, not quite ex- 

 tending to the middle of the elytra, the lower joints nearly equal 

 in length, the terminal six joints widened ; thorax scarcely twice 

 as broad as long, the sides rounded, the angles not produced, the 

 surface of equal width, dark aeneous or greenish, remotely and 

 strongly punctured, the interstices clothed with long pale hairs ; 

 scutellum rather broad, piceous ; elytra slightly wider than the 

 thorax, subcylindrical, rather finely punctate-striate, flavous, the 

 surface clothed with long greyish-white hair, the sutural and lateral 

 margins dark greenish, the sides with a subquadrate dark greenish 

 spot immediately below the middle and attached to the lateral 

 margin, another similar very small spot is (sometimes) seen within 

 the humeral callus ; below black with a slight metallic gloss ; legs 

 fulvous, the femora unarmed, the tibiae not emarginate, the claws 

 appendiculate ; prosteruum narrow, convex, and truncate at the 

 base. 



Hah. Salisbury, Mashoualaud (G. Marshall). 



From the other species of the genus described by me in a pre- 

 vious paper (Proc. Zool. Soc. 1897, p. 527) the present one differs 

 entirely in the long pubescence of the upper surface and in its 

 coloration, but not in structural characters.
