This specimen agrees fully with the North American series before 



us of this unpleasant domiciliary insect.

The species has already been recorded from Lombok, by Bormans. 



SPARATTIN^. 



Sparatta pygidiata Kirby. 



1896. Sparatta pygidiata Kirby, Jour. Linn. Soc. Lond., Zool., XXV, 

 p. 527, PI. XX, figs. 10 and 10a. [Rio [de Janeiro, Brazil].] 



Kaiteur, British Guiana, VIII, 12, 1911, (F. E. Lutz; taken sifting), 3 9, 

 [A. M. N. H. and Hebard Cln.]. 



We refer these specimens to pygidiata with doubt. We feel that 

 the genus Sparatta will be found to include a great number of yet 

 undescribed species. The synonymy and association of species 

 under Sparatta, Parasparatta and Prosparatta, given by Burr in the 

 Genera Insectorum, shows a number of serious errors. The specimens 

 before us do not agree with Brazilian material in the Academy 

 collection of S. clarkii and S. semirufa. Males of the present insect 

 may show it to be not pygidiata, but an undescribed species.
