182 THE ENTOMOLOGIST. 



" rufipalpis certissime," and the other "Ex. Gl. Hermanella, G. 

 Ehsha, 6/7/84" — no doubt the example seen by Marshall and 

 noted by him in ' Trans. Entom. Soc.,' 1885, p. 266. I find that 

 the terebra is not longer than the abdomen (it is certainly not 

 broken), and therefore scarcely agree with Marshall in consider- 

 ing the insect to be rufipalpis, Nees, which has the terebra longer 

 than the body. Being "set" in an awkward position I have 

 been unable to satisfactorily examine the specimen ; the palpi, 

 however, are certainly rufous. 



The only other British record is that of Curtis ('Guide,' 2nd 

 ■ed., col. 116). 



Genus 3, Microdiis, Nees." 



Very similar to the last, though the face is not produced to 

 anything like the same extent and the mesothorax is perhaps 

 more distinctly trilobed. As at present understood, the genus 

 is co-extensive with Eumicrodus, Forster,f and the subgenus 

 Theropliilnsl of Wesmael. 



Ten species are now known as British. I have omitted 

 M. breviccnidis, Piein.§ as I find that the single male recorded by 

 Marshall ij should undoubtedly be referred to the genus A gat his ; 

 the specimen is still in Fitche's Collection. As described by 

 Marshall, it has a distinct nervure separating the first cubital 

 cell from the first discoidal (further proof of the doubtful value of 

 this character as a means of classification), and is also anomalous 

 in having the first abscissa of the radius obsolete. The antennae 

 are 27-jointed, as stated on a label attached, and not 29 as 

 noted by Marshall. Underneath the card on which the speci- 

 men is mounted is written " Bred, 24/7/75, fr. 1. case of Coleopliora 

 troglodytclla, Guestling, Hastings"; there is also a small green 

 label bearing the number 11. This insect is very near A<jathis 

 anglica, though, of course, differing in the characters mentioned 

 above ; it is certainly not a Microdas, the face being characteris- 

 tically produced.
