the body, ferruginous-brown, paler at the anterior or basal margin, 

 and with a short humeral black line ; prothorax brownish black, the 

 anterior margin testaceous ; vertex of head blackish. A variety 

 from Bermuda, according to Saussure, has the thorax brownish black 

 with a testaceous line on each side of the anterior margin. 



Widely diffused in the West Indies and East Indies; New 

 Orleans ; Paris, France (Sauss.); S. America ; St. George's, Nov., L. 

 Mowbray, var. 



In this genus the prothorax is roundish, not truncated posteriorly? 

 but convexly arched or angulated in the middle. 



Madeira Cockroach; "Knocker.'''' (Panchlora Jfaderce (Oliv.) 

 Sauss.) 



This large species is very common in storehouses. When mature 

 it is nearly 2 inches long (48" jm ), including the elytra, which extend 

 about s mm beyond the end of the abdomen. It is fuscous or yellowish 

 brown, the elytra paler or more yellowish than the bod3 r . The pro- 

 notum is short and broad, ornamented with a double row of dots, 

 which form a lyre-shaped or V-shaped figure with the angle rounded ; 

 or sometimes it is shield-shaped. Supposed to be of African origin, 

 but now widely diffused in the East and West Indies ; Africa ; 

 South America ; Mexico, etc. 



This is probably the species called by the Bermudians "Knocker" 

 or "Drummer," owing to the loud noise that it makes at night. 

 At least it was the only large species that I found in places where 

 the noise had been heard. This name and the noise have, however, 

 usually been attributed to a different and larger species (Blabera 

 gigantea (L.) Sauss.) in the West Indies, but I am not aware that 

 the latter has been found in Bermuda. Possibly several large species 

 have the power of making the same noise. This was first recorded 

 by Uhler, from Heilprin's collection. Probably other undetermined 

 species of cockroaches occur in Bermuda.

 We were told that this small species occurs in some dwellings, but 

 obtained no specimens. It is widely diffused in most countries.
