Blaberinae 



Blaberus colosseus (Illiger)"^ 



1802. Blatta colossea Illiger, Mag. Insektenkunde, i, p. 186. [Demerara. [ = British 



Guiana].] 



This insect, with the even larger B. gigantea, represents the 

 maximum size development found in the genus and is of the 

 palest general coloration. 



This species has been recorded from New Orleans, Louisiana, by 

 Saussure as the synonymous B. mexicana. 



Blaberus discoidalis"" Serville 



1839. Blahera discoidalis Serville, Hist. Nat. Ins., Orth., p. 76. [ 9 , San Domingo.] 



The species is moderately small for the genus, with tegmina and 

 wings extending little beyond the apex of the abdomen, this 

 particularly striking in the female sex; the general coloration is of 

 the normal moderately pale brown found in numerous species of 

 the genus. 



The New Jersey adventives before us are decidedly large for 

 the species. The female from Secaucus has the dark pronotal 

 marking exceptionally extensive, covering all but the rather nar- 

 row cephalic and lateral margins. 



This species appears to gain occasionally a temporary footing 

 in greenhouses in the United States, being introduced in tropical 

 plants. 



^"* The measurements of this specimen are: length of body, 20; length of pronotum, 

 7.1; width of pronotum (crushed), 9.2; length of tegmen, 25.6; width of tegmen, 7.8 mm.
