paler lines are drab or dirty whitish on the thoracic segments, but in- 

 distinct behind, though the sub-dorsal is rather more noticeable 

 throughout, as on it are the black tubercular dots minutely ringed 

 with dirty whitish, o£ which tint also are the minute roundish-oval 

 spiracles, and also the ocellated spot with its centre black and extra 

 long hair, on the third segment ; a fine soft hair of light brown 

 colour proceeds from each tubercular dot, several from the head, the 

 second and anal segments; the ventral legs, light shining pinkish-grey, 

 are fringed with black hooks. 



The pupa is enclosed in a cocoon spun within the hammock, and 

 composed of a coarse dirty whitish silk reticulation of oval form, five- 

 eighths of an inch long ; the pupa itself is seven-sixteenths of an inch 

 in length, of moderate stoutness, broadest across the thorax and wing 

 covers, rounded above and sloped suddenly towards the head, which is 

 but little produced, somewhat flattened beneath, wing-covers rather 

 long and close to the body, the flexible rings of the abdomen taper to 

 a blunt rounded tip furnished with two minute thorny points wide 

 apart ; the colour is dark mahogany-brown, darkest on the back of the 

 abdomen, the tip black, the wing-covers and under parts rather lighter 

 brown, the whole surface shining.

AcANTHiA versus Salda. In the Ent. Mo. Mag., vol. xi, p. 186 

 (1875), Messrs. Douglas and Scott, in some synonymic notes on 

 Hemiptera, have the following on "Salda versus AcantJiia.'" —" In the 

 Syst. Eutom., 693, 159 (1775), Fabricius established the genus Acan- 

 tJiia, the first or typical species being Cimex lectularius, L., and he 

 included fourteen other discordant species. In the Ent. Syst., iv, 67, 

 211 (1794), he preserved the genus Accmthia and increased the number 

 of species to forty-five, but still kept C. lectularius as the type. But 

 in the Syst. E-hyng., 112, 20 (1803), he restricted Acanthia to two 

 species — lectularia, L., and hemiptera, Fab., and referred the species 

 previously placed in the genus to the new genera Salda, Aradus, Syrtis 

 and Tingis ; and this arrangement has since been generally followed. 

 Professor Stal, however, in his "Enumeratio Hemipterorum," iii, 148 

 (1873), has substituted the genus Acanthia, Fab., for Salda, Fab., but 

 this is certainly in contravention of Fabricius's idea, and therefore
