556 ]\Ir. John Scoft's Mvnogruph of the 



lioiicd l)y Forster; and tlie only ppccimcns of recent cap- 

 ture I have seen are one taken hy Dr. Power at Darenth, 

 in June, another at Lee, in August, and a third by 

 Mr. Douglas. According to Ilahday, he found T. (jalii 

 on the yellow ladies' bed-straw (^Galium verum); and 

 Letliierry says he takes T. vclutina very commonly upon 

 the same plant in August and September.

I have hesitated to refer the T. acutipennis, Forst., 

 to this species, as the differences he points out in the 

 antennas and elytra are so much at variance Avith that 

 of Zetterstedt. There is no doubt, however, but that the 

 T. Saundersi, i\Ieyer-Diu', belongs here, as I possess the 

 specimens Avhich he sent to Mr. Saunders, Avith his own 

 label attached.
