Now, as I found some days ago tbat these females began to fix 

 themselves to form their egg-bags, I supposed it was the moment to 

 look for the males, and I had the good fortune to find one. It is 

 quite diffex'ent from the female, its size being only 0.75 mm., or f 

 of a millimetre ; the head is rounded, with two eyes on the side, and 

 two eye-like black spots under in place of the mouth parts, which are 

 wanting ; the 9-jointed antennae are 0.29 m., or i of a millimetre, the 

 thorax and abdomen elongated and much in the same form as in all 

 other males in the Coccidce, but the wings are totally wanting and only 

 very short, little, rounded appendices indicate the place where the 

 wings should be. At the end of the abdomen, two little hairs on each 

 side support a snow-white elongated caudal seta, which is half a milli- 

 metre long, but as it is formed only by secretion it disappears when 

 put into liquid under the microscope ; between these two white tails 

 is the pointed and rather incurved penis. 



The insect takes its place in classification close to Oossyparia, 

 Sign, (the Coccus uhni, auct.), where the male is also wingless ; although 

 Signoret describes it and gives the figure as being a nymph, I am sure 

 it is a well-formed male, having seen the act of pairing many times. 

 I would suggest for the "grass-root mealy-bug^^ which can no more 

 remain as a true Coccus, the name of Fonscolojnhia graminis, in honor 

 of the author who first described it in 1834, under the rather long 

 name of Coccus radicum graminis.

OCCrRREXCE OF TWO SPECIES OF TRICHOPTERYGIA NEW TO 

 BRITAIN (INCLUDING ONE NEW TO SCIENCE). 



BY THE EEV. A. MATTHEWS, M.A. 



Several specimens of the Tricliopteryx, which I now describe 

 under the name of T. seminitcns, have long been standing in my 

 collection as doubtful examples of T. attenuata. 



But having recently examined them very carefully, I feel con- 

 vinced that they belong to a species distinct from any yet known. 

 I have also seen examples of this form in collections which have been 

 sent to me for examination, and in all such cases have returned them 

 named " T. attenuata ? " 



Any one, therefore, who possesses a specimen so named by me, 

 will probably find that it agrees with the description I give o£ 

 T. seminitens.
