SINEA. 295 
shaped in both sexes, but considerably narrower in the males than in the females: it is 
widened to the apex of the fourth segment and narrowed thence to the tip, the outer 
apical angles of the fourth segment, and those of the fifth also, in the males, being 
sometimes prominent or subdentiform. ‘The connexival margins are crenulate or finely 
denticulate. JI am unable to find any certain character by which to distinguish some 
of the females before me from those ot S. raptoria. Stal’s type ( 2 ) has been seen. 
A male from Cerro Zunil is figured.

A common Central-American species, extending southwards to the State of Panama. 
Stal’s first description appears to have been made from a single imperfect female 
example, with the long spine near the apex of the upperside of the anterior femora 
broken off. In some specimens (as in the type) the second and third spines of the 
series on each side of the ante-ocular portion of the head are reduced to small rounded 
tubercles, but in others they are as long as the anterior one. ‘The anterior lobe of 
the pronotum is set with scattered rounded or short subconical tubercles; the posterior 
lobe is very coarsely rugose, without distinct gibbosities on the disc; the lateral angles 
are moderately acute. ‘The abdomen is very similarly shaped in both sexes, somewhat 
rounded at the sides, but narrower in the male than in the female; it is gradually 
widened to the apex of the fourth segment and narrowed thence to the apex, the outer 
apical angles of the fourth segment being more or less prominent in the male; the 
connexival margins are feebly serrulate. 
S. defecta is very like an insect from the Southern United States sent to me by 
Prof. Uhler as S. spinipes (Herr.-Schaff.), a species not identified by Stal; but in the 
latter the lateral angles of the pronotum are more acute and the spines on the head 
are longer*; S. rileyi, Mont., from California, must also be a nearly allied form. The 
comparatively short third spine or tubercle of the ante-ocular series will separate the. 
present species from many of its allies. 
Ninety specimens have been examined. An example from Cuernavaca is figured. 
* These specimens, from Maryland and Florida, agree very well with Herrich-Schiiffer’s figure, though his 
species is stated to be from “ South America.”
