narrower and the coloration differs a good deal in detail, though 

 agreeing broadly. Upon color I place no reliance. 



8. MEXICANA Bormans. 



Dominica. -August (Busck). 



This specimen agrees well with de Bormans type now in the Hof- 

 Museum, Vienna. It dot's not scorn to be a common species; it is 

 well characterized by the long bifid pygidium of the male. 



9. BREVIFORCEPS Caudell. 



CaudelPs type [1907 2 , p. 174] agrees with /.. luzonica very closely; 

 the pronotum seems a little wider posteriorly (in luzonica -ides also 

 rounded). The color is a little darker. It also resembles L. mseklini. 



Further material is required before its true affinities can be 



determined. 



10. TRINITATIS Bruner. 



Trinidad, -bine, one male and one female (Busck). 



Dominica. August, one female (Busck). 



Cuba. -Cayamas, one male (Schwarz). 



Caudell's original [1907 1 , p. 169] seem- allied with L. chalybea, but 

 differs in the redder abdomen, smaller size, narrowed, truncate 

 pygidium, and basally dilated forceps. The females I can hardly 

 distinguish; those from Trinidad and Dominica really seem to be 

 L. chalybea, but I refer them here, following Caudell, as they were 

 taken together w ith the males. 



11. ROTUNDATA Scudder. 



Mexico. -Orizaba, January 9 to 1(>, 1902 (II. Osborn), one female 

 [Rchn, 1905 2 , p. 306], a bleached female. 

 Accession No. 20097, male and female. 



12. SCHWARZI Caudell. 



Guatemala. Cacao, Trece Aguas, Aha Vera Paz, male and female. 



This is Caudell's type [1907 2 , p. 173]. The quadrate penultimate 

 ventral segment of the male suggests affinity with the smaller forms 

 of Spongiphora, especially with S. pygmea, but the pygidium of the 

 male is rounded, and the fourth antenna! segmenl is short. 



13. MINOR Linnaeus. 



Philippines. Bacor, one female (P. L. Stangl). 



14. AURICOMA Rehn. 



Costa Rica. Piedras Negras (Schild and Burgdorf), one female. 

 Cat. \'o. 7080. Type of Rehn [1903 1 , p. 292]. 



This species is unfortunately based upon a single female, and so its 

 true position can not be satisfactorily determined until the male is 

 discovered. The short, stout, conical forceps distinguish it from the 

 female of /.. chalybea. It is probably allied to /.. rotundata. 



15. NIGROFLAVIDA Rehn. 



Australia. Queensland, Cairns (Koebele), Cat. No. 8168, one 

 female. Type of Rehn [1905 1 , p. 507]. 



This is a very distinct species. The male has since been described 

 by me [1908 4 , p. 18].
