does not appear that they have been noticed by naturalists as found in 

 this country, although met with in great abundance on the continent, 

 where they are said frequently to descend with the showers of rain in 

 stormy weather. The notice which appeared in No. 14 of ' The En- 

 tomologist,' not having been replied to by any succeeding correspon- 

 dent, I suspect that this curious crustacean has not hitherto been 

 noticed, or is altogether unknown as an inhabitant of our ponds and 

 ditches ; and it will indeed be a singular circumstance, should such 

 prove to be the case, that it is found in one of the most inland coun- 

 ties of the kingdom. — John Evans ; Grove House, Worcester, May 17,

185. Description of Pancalia grandis. I herewith forward you a 

 description of a very beautiful insect ; and as I believe that it has not 

 yet been described in English works, perhaps you will do me the fa- 

 vour of inserting it in ' The Entomologist.' From its size and beauty 

 I have given it the specific name of Pancalia (grandis). Anterior 

 wings narrowish, golden yellow, glossy, (terminating in a forked ap- 

 pearance towards the hinder margin) ; at the base is a semiquadrate 

 black fascia, uniting with the costa, which is purple to near the mid- 

 dle, where it is interrupted by a small, parallel, light yellow spot, be- 

 tween this and the apex is a large oblique dash of the same hue ; the 

 border, which is broad, brownish purple, extends from the apex to a 

 little before the middle of the inner margin, where it is interrupted by 

 a narrow transverse band ; a streak in the middle of the disk, and an- 

 other above, uniting before, with the costa, all shining silvery and 

 edged with deep black ; on the inner margin beyond the middle, and 

 between the opposite two spots on the costa, is another, larger, trian- 

 gular, also pale yellow ; posterior wings fuscous, strongly ciliated ; 

 head and corselet metallic purple ; tip of antennae chalky white ; pal- 

 pi yellow. The insect observed at different angles has considerable 

 variation in its tints. Expansion of the wings 6 — 65- lines. I received 

 three specimens from Mr. E. Baugh of Bewdley, who captured them 

 in the adjoining forest, one of which I presented to Mr. Bentley. —

186. Notes on a Species of Sty lops. On the 3rd of May, 1838, one 

 of my brothers brought me two specimens of Andrsena convexiuscula, 

 from both of which I obtained a Stylops, which circumstance induced 

 me to make immediate search for more of these bees, and I succeeded 

 in capturing several, almost all either containing the larva of Stylops, 

 or showing evident signs of a Stylops having escaped from them, but 

 none with the perfect insect. However, on May 6th, I had the good
