This species is very closely related to maculata. The specimens 

 at hand are all smaller, with cephalic femora very slightly but ap- 

 preciably more slender than any examples in the large series of 

 maculata before us. In addition, all but one entirely lack a black 

 transverse line bordering the unguicular sulcus distad. 



The black markings of the cephalic coxse and femora are shown 

 by the present material to be extremely variable. In the Philippine 

 specimens the cephalic coxae are black proximad on their internal 

 faces for a distance equalling about one-fourth their length, the 

 adjacent portions of the prosternum dark, the femora without 

 marking at the unguicular sulcus, with bases of ventro-internal 

 spines maculate w^ith black, the surface of the limb above these 

 markings pale. 



The Basilan male is marked as is characteristic for maculata, 

 but with entire ventral surface of prosternum suffused. The Basilan 

 female is a very dark individual, but shows the same black mark- 

 ings as the Philippine males; in this individual the pale area above 

 the ventro-internal spines of the cephalic femora being very con- 

 spicuous and in sharp contrast with the dark general coloration. 



The Society Islands male has the cephalic coxse black proximad 

 on their internal faces for a distance equal to about one-half their 

 length, the prosternum immaculate, the femora with half of area 

 proximad of unguicular sulcus black, with bases of ventro-internal 

 spines blackish.

^^ In the Academy collection. Recorded by Rehn, Notes Leyden Mus. XXXV, 

 p. 123, (1912). The female from Goenong Soegi, Lampong, Sumatra, referred 

 at that time to nemoralis, we assign to maculata, as originally recorded by Rehn, 

 Proc. Acad. Nat. Sci. Phila., 1903, p. 704, (1903).
