T. ohliquus by its more transversely truncated elytra, oblique 

 only at the sutural angle. Head with much elongated muzzle ; 

 front and emargination of the eyes clothed with golden pile. 

 Thorax quadrate, with sides slightly rounded ; surface convex, 

 regularly punctate-reticulate ; the short lateral golden fascia 

 joins the anterior marginal one near the anterior coxse. Scu- 

 tellum black, with a spot of golden pile at the apex. Elytra 

 black, closely reticulate-punctate, the lateral margin as well 

 as oblique discal vitta rufo -testaceous. Body beneath finely 

 griseous pubescent ; a lateral stripe on mesosternum and meta- 

 sternum and apical margins of ventral segments golden tomen- 

 tose. The abdomen is slightly vespiform in both sexes, more 

 slender in the male. The antennaj are pitchy red, the fifth 

 joint being dilated at apex and joints 6 to 10 serrate and 

 thickened ; in T. laticornis (Klug) the fifth joint is linear.

This species is an exact mimic of a small bee of the genus 

 Megachile (or allied thereto), which frequents the same flowers.

The resemblance in facies and colours between this and the 

 typical species of the genus is very great ; but it diifcrs in the 

 elytra being a little prolonged, narrowed and rounded at the 

 apex, and in the antennae having the sixth to eleventh joints 

 very greatly compressed and dilated, with the fifth joint slender 

 and linear.
