Dromodesmus longipes, sp. nov. 

 PI. IQ. Figs. 128-133; PI. 20, Figs. i,U-i.3.S 



The general color of most of the types as at present is 

 brownish grey, with legs fulvous and antennae brown. But 

 the only specimen in full color, the male type, is deeply olivea- 

 ceous or nearly black above, excepting the processes or the keels, 

 which are yellow. Lighter, brownish yellow beneath. Anten- 

 nae brown. Legs lighter brown, fulvous beneath proximally. 



Antennae long (see PI. 19, Fig. 131, for proportions of 

 joints). Surface of head minutely granular, with fewer 

 longer setigerous granules. A'ertigial sulcus distinct to level 

 of antennae. 



Collum with anterior and lateral margins together forming 

 a nearly evenly convex curve. Caudal angles a little less than 

 rectangular, extended slightly caudad. (PI. 19, Fig. 128.) 



Keels of anterior segments bent up and carried a little 

 above level of dorsum, in going caudad becoming more nearly 

 horizontal. All margins of keels wholly smooth. Dorsum 

 of a typical metazonite with a distinct transverse furrow in 

 front, of which there is a median longitudinal furrow, often 

 irregularly developed, giving a number of quadrangular areas ; 

 a row of smaller areas along caudal border. Two transverse 

 rows of tubercles caudad of the transverse suture and one in 

 front, the latter of six widely separated tubercles. ( For form, 

 see PI. 19. Fig. 129.) 



Cauda triangular, with tip narrowly truncate ; a large 

 setigerous tubercle on each side, with a smaller one more 

 dorsal in position between it and the tip. Mesal margins of 

 valves raised. Anal scale angular behind, with a setigerous 

 tubercle each side of the angle. (PI. 19, Fig. 130.) 



Form of posterior legs of male as shown in PI. 20. Fig. 134.
