100 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I25 



Abdomen : Tergite of segment i tan in middle, dark brown on 

 sides, with short tan hairs; the pleurites dark brown, with long tan 

 hairs that reach segment 3. Segment 2 dark brown, gray-pruinose, 

 with some tan hairs and several black ones. Other segments dark 

 brown, completely gray-pruinose, with short black hairs and a few 

 yellow scalelike hairs. Sternites brown, with gray pruinosity. 



Genitalia : Cercus (pi. 28, fig. 125) dome-shaped, its height about 

 twice the length (width). Anal lobe (pi. 28, fig. 125) pointed at its 

 dorsal extremity and expanded ventrally, similar to that of aguirrei. 

 Genital rod (pi. 28, fig. 124) with basal dilatation oval, the base of 

 rod rather pointed, pigmented only along narrow central region ; 

 apical expansions of genital fork broad, ribbonlike, the inner basal 

 angle somewhat prolonged and slightly pigmented. Ovipositors (pi. 

 28, fig. 126) triangular in shape, the base slightly greater than the 

 length, the inner margins parallel and somewhat more heavily sclero- 

 tized than the rest of the structure. 



Pupa (pi. 36, fig. 278, and pi. 39, fig. 318). — (First description of 

 pupa other than respiratory apparatus.) No granulosity on thorax; 

 4 long, simple trichomes on either side of midline of thorax. Dorsal 

 surface of abdominal segments : No granulosity ; spines on segments 

 3 and 4 are anteriorly directed, those on segments 5-8 are posteriorly 

 directed; segments 3 and 4 with 8 simple spines in transverse row 

 somewhat before the posterior margin, the row divided in two by a 

 median separation ; segment 4 also with row of small but heavy 

 plaques, like minute spines, somewhat behind the anterior margin, 

 without median separation ; segment 5 with uninterrupted transverse 

 band of 90 simple spines somewhat behind the anterior margin, the 

 band composed of 2-3 irregular rows ; segments 6-8 each with an un- 

 interrupted single row a little behind the anterior margin, segment 6 

 with 102 spines, segment 7 with 90, and segment 8 with 64. Ventral 

 surface of abdominal segments : Band of granulosity across the an- 

 terior fourth of each segment; all spines are anteriorly directed; seg- 

 ments 3 and 4 each with a single simple spine on either side of the 

 midline about three-fourths the distance from the anterior margin, 

 the two spines well separated ; segments 5-7 each with transverse row 

 about three-fourths the distance from the anterior margin, composed 

 of 4 simple spines, the two spines on either side of midline well sepa- 

 rated, about equal to the median space between the two inner spines ; 

 each of the lateral margins of segment 9 with 4 simple and i bifid or 

 trifid long hairs. Terminal spines well developed, about 60 ju, long. 



Respiratory apparatus (pi. 36, fig. 278) of each side arising a little 

 behind the anterior margin of the thorax; composed of 4 inflated,
