106 PROCEEDINGS OF THE ACADEMY OF [March, 



Allied to S. trinitatis Bruner, with a specimen of which it has 

 been compared, but differing in the less prominent eyes, the broader 

 interspace between the same, the more tectate dorsum of the prono- 

 tum, the broader and differently shaped distal portion of the tegmina 

 and very different character of the apex of the abdomen. 



Size small; form shghtly compressed, a distinct median carina 

 present from the cephalic margin of the dorsum of the pronotum 

 to the apex of the abdomen, the dorsum for this reason being tectate; 

 surface of the thoracic segments, dorsum of the head and to an 

 extent of the limbs ruguloso-punctate. Head with its dorsal length 

 three-fifths that of the pronotum in the male, half the length of the 

 same in the female; occiput distinctly arcuate and provided with a 

 pair of converging irregular channels; interocular space about half 

 the greatest width of the fastigium, provided with a shallow but 

 distinct sulcus which extends to the fastigial margin; fastigium 

 distinctly broader than long, rounded rectangulate, very slightly 

 acute in the male, the immediate angle subtruncate, surface with a 

 pair of rather low parallel ridges flanking the central sulcus, margins 

 with a distinctly elevated rim; fastigial process slightly protuberant 

 when seen from the side, subtruncate, forming an appreciable 

 angle with the dorsum of the fastigium and gently curving ventrad 

 into the slightly retreating face; frontal costa continuous, very 

 slightly expanding ventrad of the ocellus, punctate dorsad, sulcate 

 from between the antennae ventrad; supplementary facial carinse 

 ■ > slightly sinuate and slightly divergent ventrad; 



V, ,y areas usually occupied by the lateral foveolae 



•.'. .7 strongly punctate; eyes elliptical, longer and 



narrower in the female than in the male, length 

 \\ / very considerably more than that of the infra- 



ocular portion of the gense, distinctly prominent 

 in both sexes. Pronotum with the greatest 

 caudal width of the disk contained one and 

 one-quarter (cf) to one and one-third (9) times 

 in the length of the disk, distinctly tectate; 

 cephalic margin slightly arcuate, caudal margin 

 rotundato-truncate with a well-marked median

 Dorsal outline of in the female than in the male; median carina 

 turn 'o^f t*y°pe" distinct, subequal, cut by three transverse sulci, 

 (X 4.) metazona about half the length of the prozona; 



lateral angles not at all strongly marked, slightly converg-
