brown in the male and almost yellow in the female. Yerbury met 

 with it in large numbers at Walton-on-Naze, sweeping it on the first 

 occasion (26/6/09) from the ditch separating the salt from the fresh 

 water marsh, and two or three weeks later he again found it in the 

 same locality rimning actively about on the sea wall. 



Pygmsea, Zett. — A common and well-known indoor insect, found 

 more rarely in the woods or fields. Our insect is the dark or type 

 form, the pygmsea of Zetterstedt, and it is doubtful whether we have 

 typical hracliyneura, Egg, the variety in which the thorax is red or 

 yellow. The nearest approach to it is given by an obscm-ely reddish 

 thorax and red antennae in a few examples only out of the many 

 I have examined. Individuals, however, with yellow legs but in other 

 respects black are more often met with. Becker, dismissing the type 

 in little more than a couple of lines, devotes his description to the 

 variety hracliyneura, and speaks of the hind tibiae being tenderly (zart) 

 ciliated. In my judgment, however, the cilia are both strong and 

 sparse, at any rate in the insect commonly accepted as pygmsea 

 with us. 



Lata. — Two males, taken by sweeping in Stoke Wood 20/9/08. 

 Agreeing in size and many other particulars with angelicas, it may be 

 differentiated from that species by the duU frons, the not only slender 

 but also to my eye the somewhat lengthened fore tarsi, by the stout 

 abdomen and the form of the hypopygium with the absence of bristles 

 or of any special hairy development on it. 



Angelicse. — An autumnal species, frequenting commonly the 

 flowers of Angelica and Heracleum, and also to be obtained by general 

 sweeping. Its small size and bare pleurae, distinctly if only moderately 

 shining frons with its closely approximated supra-antennal bristles — 

 an xmusual condition in these very small forms, the nonnal fore tarsi 

 (neither specially slender nor stout) together with the small bristle at 

 the coi'uers of the hypopygium leave its identification in little doubt. 



Longipalpis. — A scarce and very interesting species, of which only 

 five males have been obtained ; the dates and localities being Stoke 

 Wood 2/8/05, 11/6/06, 11/6/06, Westhide 7/6/06, and Coldborough 

 Park 20/8/06. The female has not been met with or possibly has been 

 overlooked, since it would almost certainly lack the striking character 

 which has suggested the name of the species, namely, the very large 

 and almost bare palpi. These remarl able organs resemble in shape 

 the large palpi of Phora nudipalpis rather than those of projecta. 



Gregaria. — The only occasion on which I ever met with this tiny
