Longicorn Coleoptera of Tropical America. 1 29 



T. obliquus 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 antennas 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. 



II. Elytra cuneiform, reaching a little beyond the base of the 

 abdomen.

The resemblance in facies and colours between this and the 

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

 elytra being a little prolonged, narrowed and rounded at the 

 apex, and in the antenna:; having the sixth to eleventh joints 

 very greatly compressed and dilated, with the fifth joint slender 

 and linear.
