276 Mr. R. Shelford's Studies of the BlattidcV. 



IV. The Type of U'pilavijmc hrasilicnsis, Fab. 



Fabricius' description in his " Systema Eatomologia;," 

 1775, p. 272, of this species is as follows : — 



" B. pallida, abdominc atro. 



" Habitat in Brasilia. 3Ius. Dom. Banlcs. 



" Paulo major B. lapponica. Tota pallida, abdomine 

 subtus atro. Antenna.^ fuscEe." 



So brief a description of a member of a genus including 

 numbers of cryptically-coloured species, renders its deter- 

 mination by subsequent authors almost impossible. The 

 synonymy of the species according to Brunner (Nouv. 

 Syst. d. Blatt. 18G5, p. 159) is :— 



EiyilmniJra brasilicnsis, Burm. Handb. ii, p. 505 (1838). 



Blatta maculicollis, Serv., Ins. Ortli. p. 02 (18o9). 



? Blatta (jrisea, De Goer, Mum. Ins. iii, p. 570, n. 7, pi. 

 44, f. 9 (1778). 



? Blatta f/risca, Oliv. Enc. Moth. T. iv, p. 810, n. 35. 



? Fhyllodromia hurmcistcri, Gucr. lie de Cuba, Anim. 

 Art. p. 845 (1857). 



None of these species can be recognized with certainty, 

 since the descriptions of them are inadequate and the 

 types of some are missing. The Hope Museum at Oxford 

 contains some drawings made by the late Professor West- 

 wood of several of Serville's types, amongst others the type 

 of Blatta maculicollis, and on conipariug this with the Fa- 

 brician type of Blatta hnsilie-iisis in the Banksian cabinet 

 at the British Museum I have come to the conclusion that 

 the two species are distinct. Brunner's own description 

 does not apply to the Fabrician type, nor to the drawing 

 of maculicollis, and I would therefore suggest the name of 

 BinlampTci hurmcistcri, Guer., for this species. B-pilampra 

 Imrmeistcri has been well described also by de Saussure 

 (Mem. Mex. Blatt., p. 181), though I am by no means cer- 

 tain if this author had the opportunity of seeing Guerin's 

 type which came from Cuba. Examples in the Oxford 

 Museum from Jamaica, Guiana and Brazil appear to be 

 identical with each other and they correspond well with 

 Brunner's and de Saussure's descriptions. It remains then 

 only to give a detailed description of the Fabrician type.
