136 THE CANADIAN ENTOMOLOGIST. 



A NEW ROACH FROM THE PHHJPPINES. 



BY A. N. CAUDELL, WASHINGTON, D. C. 



Salganea huineralis^ new species. — Size medium. General colour 

 black, tlie under surface of the legs and of the body, except the last 

 abdominal segment, or subgenital plate, and the mouth, except the 

 mandibles, and also the vertex, reddish. The base of the elytra in the anal 

 field is also tinted with reddish. Antennae dark, hairy. Wings and elytra 

 mostly missing. Anterior femora unarmed. Pronotum very slightly 

 notched anteriorly, the disk with the usual irregular V-shaped depression 

 and unetjual elevations, but not distinctly tuberculate, the entire surface 

 punctate. Base of the elytra smooth in the anal field, the costal field 

 densely and coarsely punctate. Abdomen punctured, finer below along 

 the median line, the segments transversely sulcate anteriorly above., more 

 profoundly so towards the sides of the last three ; seventh segment laterally 

 irregularly crenulate, the latero-posterior angles divergent. Supra-anal 

 plate rugulosely punctate, the posterior margin dully serrate ; subgenital 

 plate marked as the supra-anal plate, posteriorly emarginate. Cerci short, 

 triangular, hairy, reddish in colour. 



Length, 30 mm. ; pronotum, 7.5 mm. ; width, pronotum, 11 mm. ; 

 abdomen, 14 mm. 



Type No. 9812, U.S.N.M. 



One female, one nymph, received from CS. Banks, of Manilla, P.I.; 

 no definite locality given. 



This species seems to be the most nearly allied to Salgaiiea rugulata 

 of Saussure. but is decidedly larger than that species. The organs of 

 flight are much mutilated, as is so often the case with members of this 

 genus, as well as Pa?iesthia, and probably other related genera. The elytra 

 and wings are apparently chewed off, and so uniformly as to appear like a 

 short-winged form, if not carefully examined. Of the tiiree species of 

 Salganea and Panesthia examined by me, more than one half of the speci- 

 mens are thus mutilated. I can assign no plausible cause for the 

 phenomenon. 



The nymph is reddish yellow, lighter below, except towards the tip of 

 the abdomen. The punctures of the surface are not so deep nor distinct 

 as in the adult.
