HEMIPTERA 141 



extremely slender annuliform collar ; anterior margin slightly emarginate, base sub- 

 truncate. Proxyphus marginate laterally. Costal margin of elytra very narrow, slightly 

 dilated basally. Clavus distinct. Membrane biareolate. Hamus absent. Anterior 

 and intermediate coxae as long as, or a little longer than the femora, incrassate, 

 posterior femora a little remote from lateral margins of abdomen ; posterior tibiae six 

 times as long as tarsi, third tarsal segment by a little the longest, second and third 

 inserted subapically. Claws somewhat large, dilated internally near the base, arolia as 

 long- as the claws, free, a little thicker at the base, ribbon-like.

Plate IV. figs. 18—20. 



Dark blackish-brown ; base of vertex, legs (except broad bands on the posterior 

 femora), first segment of antennae etc., pallid ; base and apex narrowly of exocorium, 

 posterior part of scutellum narrowly, rufotestaceous ; membrane hyaline, rufotestaceous, 

 more or less fumate apically. Beneath more or less sordid rufotestaceous, sterna and 

 pleura more or less blackish. Second segment of antennae 2f to 3^ times longer than 

 first, three-fourths longer than the head, and 3^ longer than the third segment which is 

 a trifie longer than the fourth, each segment a little thinner than the preceding ; first 

 and the basal half of the second — smooth ; apical half of second and the two ultimate, 

 pilose. Pronotum subrugulose transversely, except on the anterior callosities, lateral 

 margins sinuately divergent, lateroposterior angles rounded, base nearly three times as 

 wide as apical margin. Elytra smooth, somewhat shining', rounded laterally ; corium 

 without median nervure, costal nervure vanishing before attaining half the length of the 

 corium. Cuneus rounded basally. Antennae and eyes in a line, and about the middle 

 of the head, as seen in profile. Fourth segment of rostrum reaching nearly to apex 

 of posterior coxae, one-sixth longer than third, first three subequal in length. 



$. Eyes very large, prominent, one of them one-fourth to one-third wider than 

 the vertex ; head three-fourths longer than one eye. 



?. Eyes much smaller, vertex nearly as wide as the two together. Head more 

 than twice as long as one eye. Seventh abdominal segment beneath widely roundly 

 emarginate, terebra reaching to middle of abdomen. 



A very variable species, both structurally and in colouring. Pronotum and 

 scutellum sometimes widely pallid, exocorium rufobrunneous ; antennae occasionally 

 more or less annulate, pallid and blackish. Abdomen beneath : each segment apically 

 blackish, basally rulescent, or entirely bluish-black. Tibiae apically and basally black. 

 Posterolateral angles and a wedge in middle of the base of pronotum, pallid.
