DRAGONFLIES IN 1901. 3^ 



of hairs between antennae, a tuft on the vertex, and two tufts 

 containmg some very long hairs (or bristles) on occiput ; hind 

 margin of occiput concave. Eyes small, bluntly conical (nearly 

 spherical) at front lateral corners of head. Antenncs 7-jointed ; 

 basal two short and swollen; next three rather longer, more 

 slender, and each with a long hair ; distal two longer and quite 

 slender, possibly having had a whorl of hairs at one time ; length 

 of anteuucie about 4 mm. Mask (PL I. a) large, deeply spoon- 

 shaped, covering the face, and reaching back to the insertion of 

 the mid-legs; mediam lobe obtusely pointed with slopes slightly 

 concave ; lateral lobes with outer lateral margin slightly concave, 

 inner lateral margin convex, distal margin finely crenated and 

 divided into eight teeth, each bearing spines, on some teeth as 

 many as six in number (PL I. h) ; moveable joint rather short, 

 blunt* ; mental setfe, eleven in each comb ; lateral setfB, about 

 seven on each side (eight in one case). Prothorax narrow, pro- 

 duced laterally into a point on each side bearing a few long stiff 

 bristles. Pleura rugose, with a few long stiff bristles. Wings 

 rough, with scattered long stiff bristles like those on pleura. 

 Legs, fore about 105 mm. long, mid about 15 mm., hind about 

 18 mm. ; hairy except, apparently, femora of mid and hind pairs, 

 which, however, are rough ; they all bear a number of long, 

 scattered, stiff' bristles (many broken off) ; the femora with a 

 couple of dark bands. Abdomen very rugose ; stiff hairs along 

 the distal margin of the segments, these being longer in the mid- 

 dorsal line ; one or two still longer stiff bristles among the rest 

 on most of the segmental margins ; a slightly lighter mid-dorsal 

 line, the colour being a little darker on each side of it ; lateral 

 margins hairy, especially in tufts near the front and back of each 

 edge of the segment, on segment nine the marginal hairs much 

 longer ; lateral hooks on segments eight and nine, those on nine 

 being much the longer ; no dorsal hooks. Appendages rough, 

 pointed, hind ones a little longer than dorsal one, laterals rather 

 more than half hind ones. 



Gomphus vulgatissimus was found fairly numerous between 

 25th and 28th May by one of the streams in the New Forest ; but 

 specimens were as a rule not very easily taken. They were at that 

 date rather immature, and were generally seen settled upon, or 

 flying round, some of the larger bushes and small trees. Near 

 Oxford, Messrs. A. H. Hamm and W. Holland found the range of 

 this insect to be rather more extended than previously. 



Cordidegaster anmdatus was common in some parts of the 

 New Forest in August, and on the 3rd of that month a female 

 was watched as she was ovipositing in BLickwater stream by 

 dipping the tip of her abdomen rather forcibly, but apparently 



'''■ Possibly the points may have been broken off in specimens mounted 

 for microscopical examination ; but all were alike.
