Centrali- Americana ' as " Sparatta pelvimetra var. rufina,^' agrees 

 Avith the descriptions of typical 8. pelvimetra, Serville, even to 

 the thorax being reddish ; and as such I shall regard it, unless 

 further material, when obtained, proves it to be a distinct 

 species. 



Sparatta ClarTcii and S. pygidiata differ from 8. ScTiotfi, Dohrn, 

 in the antennae. Those of 8. Schotti are described as brown, 

 with joints 9-12 pale. There is a female specimen labelled 

 8. Schotti from Mexico in the Godman and Salvin collection, 

 which has brown antennse, with the two basal joints blackish 

 (8 only preserved). The pygidium is moderately long and 

 broad, with the lateral angles well marked, and the central part 

 projecting rectangularly and longer than the basal part. It is 

 evidently distinct, for the head and pronotum, which ought to be 

 red in typical 8. Schotti, are shining black. It may be called 

 >S^. Bormansi. 



Sparatta semirufa, sp. n. (PI. XX. figs. 4, 4 a.) 



Long. Corp. cum forcip. 10-12 millim. ; long, forcip. 2-3"5 

 millim. 



E-ufo-testaceous ; tegmina and exposed part of wings violet- 

 black, shining ; antennae 14-jointed, and, as well as the palpi, 

 luteous or brownish yellow ; head with a large square brownish 

 patch in front, mouth-parts clothed with yellowish hair ; pro- 

 notum usually with a short dark dash on each side ; elytra with 

 the margins, and sometimes the base, shading more or less into 

 testaceous. Porceps long, with the basal half nearly straight, 

 and with several serrations on the inner edge as far as a strong 

 tooth just beyond the middle, then gradually incurved. In the 

 female they are stouter, and the tooth, which is placed before the 

 middle, is much smaller and more obtuse, and the denticula- 

 tions preceding it are much smaller than in the male. The 

 pygidium in both sexes is short and broad, with the lateral 

 angles projecting strongly outwards, and the central part 

 moderately convex. 



Sab. Igaurassu (near Pernambuco), Brazil. 



This species agrees with the very brief description of ^S*. Schotti, 

 Dohrn, except that in 8. Schotti the antennae should be brown, 

 with joints 9-12 pale.
