1. H^MATOPOTA 335 



behind the middle of the eye Avith a smallish rounded spot and then contract- 

 ing to a line, and subsequently with two dentations (especially downwards), 

 but ending in a point almost at the eyemargin level with the lower part of the 

 large lower frontal callus ; hindmargin of the eye all brownish purple and 

 narrowly uniting all the bands except the middle one, and with a projection at 

 the middle towards this middle band ; the second and fourth brownish purple 

 bands converge narrowly on the front margin almost to each other ; this 

 description (made from a female taken at Barton Mills in Suffolk) does not 

 exactly agree with fig. 223, more especially in the shape of the isolated middle 

 band, and I find that the eyes vary somewhat in these markings, the lower 

 purple band sometimes enclosing the fourth almost simple light band (not 

 indented so much as in fig. 223), while the middle purple band may be entire 

 from front to back. Antennae about one and a half times as long as the head ; 

 two basal joints black, but mainly covered with grey dust which leaves only 

 almost the end half of the basal joint shining black on the upper side and 

 rather more at the sides ■ basal joint rather dilated for a considerable length 

 about the middle (but not obviously ovate) and quite two and a half times 

 as long as its broadest part, bearing small black bristles all over and with 

 some thin pale hairs beneath on the basal half ; second joint short cup-shaped, 

 extending on the upper side cap-like over the third joint, and bearing black 

 bristles similar to those on the basal joint ; third joint much longer than the 

 basal joint, obscurely brownish red on the basal half of its first segment 

 ( = all except the three terminal segments), but otherwise dull brownish black, 

 and this first segment (apparently composed of two segments, because of the 

 annulated constriction at about a quarter from the base is more than three 

 times as long as broad, thickest at about a third from its base but thinner 

 at its base and end than all about its middle, and with several short black 

 bristles above and a few beneath at the end of the constriction near its base ; 

 the three terminal annulations about as thick as the end of the basal segment 

 and hardly tapering, the first two being subquadrate and the terminal one the 

 longest. 



Thorax greyish black (not dull black as in the male) with five yellowish 

 grey or grey lines which all begin quite in front, and of which the middle one 

 is narrow and entire while the next pair are rather interrupted at the suture 

 but are continued (more or less indistinctly about raidM^ay) to the hindmai-gin ; 

 the lateral stripes are broad and rather vague and divide indistinctly just 

 after the suture but reunite later on so as to enclose a greyish black island 

 spot ; along the hindmargin the grey strij^es are more or less connected. 

 Pubescence pale greyish yellow, short, rather depressed and rather sparse all 

 over, though several longer erect black hairs occur on the prsealar calli and 

 also a few above the wing-base ; pleurje ashy grey, bearing all over long 

 rather silky greyish white pubescence. Scutellum all dark brownish grey, 

 bearing only moderate pale pubescence. 



Abdomen in a well-marked specimen greyish brown-black but ashy grey on 

 a moderately broad dorsal line, on all the hind and side margins, and on a pair 

 of moderately large rounded spots on each segment (after the basal one) in 

 the middle of the brownish black space, and sometimes whitish ashy grey on 

 the sides, but on the fifth to seventh segments these ashy grey markings tend 

 to coalesce and towards the tip occupy nearly the whole of the segments. 

 When viewed from behind the dark markings appear to form blackish brown 

 circles on the second to fourth segments, of which the inner arc is broad and 

 the upper arc on the third and fourth segments is partly hidden under the hind- 

 margin of the preceding segment, while on the fifth and sixth segments the 

 brown markings are fairly well defined, and when viewed from behind the grey 

 markings appear pale ashy grey with a slight yellowish tinge. In other 

 specimens the grey markings may be more extensive and less defined, though 

 at the same time the pair of spots on the second segment may be small ; tlie 

 fifth to seventh segments often have inconspicuous ferruginous sides. 

 Pubescence short depressed and more extensively greyish yellow than in the 

 other species, but more or less blackish on the dark brown ground colour, and 

 longer and less depressed down the sidemargins, while it is black on the 

 sidemargins of the fifth to seventh segments except at the hind corners. 

 Belly darker yellowish ashy grey or whitish grey with a broad slightly darker
