With regard to tlie antennae, Blackburn overlooked the con- 

 tradiction contained in Pascoe's description of 2\ brevicorne 

 (Journ, of Ent. 1866, p. 454). In the Latin part, this reads 

 " antennarum clava triarticulata," while in the longer English 

 notes below, he writes " club of the antennte four-jointed." 

 From my examination of the five species tabulated below, I find 

 the club to be as follows : — 



T. punctipenne'^di&c. — CXwh of 3 joints, easily differentiated 

 from the preceding joints. 



2\ brevicorne Pasc. — Club of 4 joints, the 8th transverse, but 

 more triangular than the 9th joint. 



T. gracile Pasc. — The slender club may be considered as having 

 three or four joints, the 8th being intermediate in size between 

 the 7th and 9th, but so much smaller than 9, and in shape like 

 7, that I should consider the club as rather 3-jointed than four. 



T. insigne, n.sp. — Club of 4 joints, easily differentiated from 

 the preceding joints. 



T. quinque-coriiutum, n.sp.— Club of 4 joints, easily differen- 

 tiated. 



The five species can be readily tabulated by the character of 

 the horns of the male as follov/s : — 



{l.)Clypeal hoi^ns sep-ATixte, starting from near the corners of the clypeus, 

 and nearly vertical. 

 Frontal horns gently incurved, pointing upwards, with semicircular 

 fringe of red hair from near the apex on the outside to about | 



way down the inside punclipenne Pasc. 



{2.)Glypeal horns shorter than in (1), separated, but not starting from 

 opposite corners of the clypeus, and diverging. 

 Frontal horns semicircularly incurved, pointing inwards, with smaller 



fringe of red hair round the apex, above and below ... 



brevicorne Pasc. 



{3.)Clypeal horns connected at base, starting from the middle of the 

 clypeus, forming the letter Y, with the conmion base wide. 

 Frontal horns moderately incurved, pointing upwards, nearly as in (1), 

 with fringe of yellow hair starting from near the apex on the 



outside and continued half way or more on the inside 



gracile Pasc. 



{i.)Clypeal horns abbreviated into wide conical tubercles at the corners of 

 the clypeus.
