432 TANANID.^ 



calli represented by an indefinite moderately shining rather greyish black 

 isolated stripe on each side running from the lower eye-angle to the mouth- 

 edge ; pubescence consisting of moderately numerous long black hairs which 

 are absent from the facial and oral calli and from a small space between and 

 just above the oral calli, and some yellow hairs occur outside the oral calli ; 

 jowls (behind the buccal calli) greyish yellow, with the pubescence all yellow 

 on their lower part and behind the mouth but black on their upper part and 

 near the eyes ; back of the head flush with the eyes, blackish grey, and 

 bearing a very minute black bristly postocular fringe ; vertex dull black, 

 elevated, and bearing mainly black hairs but sometimes with some jiale hairs 

 intermixed ; frons obscure greyish yellow, with only just the top angle 

 shining black. Proboscis black, twice as long as the palpi ; palpi brownish 

 or slightly greyish black, hardly dilated anywhere but long and cylindrical, 

 and bearing rather bristly black pubescence but with some yellowish hairs 

 beneath about the base. Eyes bare ; facets on nearly the louver half smaller 

 than those on the u]iper part, but with no sharply contrasted division at the 

 semicircular boundary line, and on the back part the small facets extend 

 upwards a little but not nearly to the vertex ; eyes in life (fig. 247) similar 

 to those of the female, brilliant green, but darker green (or when viewed from 

 above bluish) and not at all coppery on the larger facets, which occupy the 

 two-thirds of the ej^e above the brown middle band, or from another point of 

 view the upper two-thirds of the eyes green and the lower third yellowish 

 green ; the tAvo brown spots near the middle are united in a long thin bright 

 brown line which extends from near the foremargin (at almost as high up as 

 the top of the facial callus) to more than two- thirds across the eye, slightly 

 dilated at the discal end of the line {i.e., on the usual middle 

 spot) and very slightly contracted before that ( = the connect- 

 ing line between the two spots) ; lower brown spot small and 

 narrow, and also very transverse, and placed as in fig. 247 ; 

 it is only when viewed from above in certain lights that the 

 usual upper spot on the disc of the eye can be traced as a 

 rounded and faintly brown spot placed as in fig. 247, and in 

 just about the same light and from almost the same point 

 of view a slight brown spot can be traced on about the 

 middle of the back margin of the eye which indicates where 

 Fici. u-.—chryi<jpi the usual emargination would occur if the whole hindmargin 

 Left eye"i/i'ife. ^^ ^^® ^^^ Were darkened as in C. ccecutiens, and the lower 

 brown margin of the eye can be seen to be faintly extended 

 further up the back of the eye almost to this spot. Antennae dull black, 

 slightly greyish and in some lights rather shining ; basal joint not much 

 larger or stouter than the second, and bearing conspicuous long black bristly 

 pubescence all over; second joint with similar but shorter pubescence, and 

 with an apparent annulation or constriction at about three-fourths its length ; 

 third joint subulate, but slightly thinner about its base, and rather upturned 

 at its tip. 



Thorax black, slightly shining but with faint indications of two broad 

 greyish stripes separated by a narrow dark one ; humeri and prothorax 

 greyish ; pubescence fairly abundant and suberect, mainly black but with 

 numerous shorter depressed thinner brownish yellow hairs intermixed, though 

 the two rather shining black stripes outside the faint grey stripes are usually 

 restricted to rather shorter black hairs which are connected in front with the 

 denser stripe of black pubescence against the dorso-pleural suture ; the 

 brownish yellow hairs become moi'e erect about the hindmargin of the disc and 

 though inconspicuous almost supersede the black hairs tliere and on the disc 

 of the scutellum ; a dense stripe of black pubescence occurs on the outer 

 side of the ridge against the dorso-pleural suture, but on the posterior part of 

 the dorsal side of this ridge there are some dense tawny or blackish tawny 

 (rarely inconspicuous) hairs, which are continued over the wing-base and 

 connected with similar hairs on the postalar calli. Pleurje grey dusted, with 

 the pubescence dense and tawny (but not so bright tawny as in C. ccecutiens) 

 on the prothorax, on the upper and hind parts of the mesopleurae, and on the 

 metapleurae ; the pubescence on the lower anterior part of the mesopleurce is 

 sparse and sometimes black, and on the sternopleurse less scarce than in
