Penicillidia jenynsi (Westw,), Speiser, Arch. Naturg. 67 (1) 

 1901, p. 38. 



1 ^ and 8 $ ^ (and 1 larva) sent from Tainau, Formosa ; 

 found on Minioptcras schrcihcrsii (H. Sauter). Type $ and 

 the other specimens in the Cambridge Museum. The $ 

 is here described for the first time, only the $ having been 

 known hitherto. 



Dr. P. Speiser informs me, after examining some of the 

 specimens, that they belong to the species regarded by him 

 as P. jenynsi, and described by him (/. c.) under that name. 

 As Westwood's type of P. jenynsi unfortunately cannot be 

 found, it has not been possible to make a compari.sou in 

 order to ascertain whether the form under consideration 

 is certainly identical with the P. jenynsi of Westwood. 



The colour of the lirnily chitinised parts is rather pale yellowi.sh- 

 brown. Both sexes agree with Speiser's description in the following 

 particulars : length about 2-5 mm. ; head with numerous strong 

 bristles between the eyes : the bristles continue down the margins of, 

 but are absent from the surface of, the cheeks ; maxillary palps with 

 numerous .strong bri.stles, the terminal ones very long ; nnder surface 

 of thorax * markedly curved in the longitudinal direction, with a 

 dark middle line .somewhat impressed at the ends. The legs are as 

 described by Spei.ser. 



* The curvature of tlie surface renders it hard to estimate correctly 

 the projiortion of lengtli to breadth. In the table given by Spei.ser 

 (op. cit.f p. (JG) P. jcnynsi is ])laced in a section of the genus in whicli 

 tlie thorax is longer llian broad. In the specimens from Formosa 

 the breadth appears at any rate equal to, if not sliglitiy greater than, 

 the length.
