The scutum is usually comparatively narrowly elongate, meas- 

 uring approximately A.O ram. long and 2.5 mm. wide. Its color is 

 typically dark brown to black, but reddish specimens also occur; 

 the legs may be entirely reddish or reddish centrally on each 

 segment with paler anterior and posterior bands (see next para- 

 graph) . The scutal pimctations may be dense enough to suggest 

 H. rufipes , but those in the center are shallower and smaller 

 Than elsewhere, while in H. rufipes they are deep and quite uni- 

 form in size and depth. The parma may appear to be merely a 

 median festoon and is the same color as the rest of the scutum. 

 The subanal and adanal shields have rounded contours; the adanal 

 shields are quite large. 



Heavily punctate males, as seen among series from Libya, 

 Algeria, Egypt, Romania, and elsewhere may suggest H. turanicum 

 (page 531). The legs of H. marginatum , however, lack the con- 

 spicuous enamelling characteristic of those of H. turanicum . 



Females ; The genital apron is a large, robust widely trans- 

 verse oval or triangle with a strongly bulging profile; it is 

 most characteristic. The scutal punctation consists of numerous 

 small, shallow, distant punctations over the entire surface (they 

 may be alirost medium size and slightly deeper and closer), and a 

 few larger and deeper punctations scattered among them chiefly 

 on the anterior half of the scutiun. The basic punctation in some 

 specimens is so shallow as to give scutum a rather smooth appear- 

 ance, especially posteriorly. The central field between the cer- 

 vical grooves is usually lighter (more reddish) than the dark 

 lateral fields. The scutum appears to be exceptionally wide, 

 its length- width ratio being about equal or shorter than wide. 



Females of H. marginatum and H. turanicum are quite similar 

 but the bright enamelling of the leg segments of H. turanicvim 

 distinguishes them. In most specimens of H. ttu:anicum the 

 genital apron is not so widely triangular and the scutal punc- 

 tations are more numerous and discrete than in H. turanicum . 



The larva and nymph of H. marginatum have been described and 

 illustrated by Bernadskaia (T939C; and Feldraan-Muhsam (1948).
