TWO NEW PTINID.4^.. 



BY C. SCHAEFFER, MUSEUM OF THE BROOKLYN INST. OF ARTS AND 



SCIENCES. 



A number of new species, either entirely new or known only from 

 Mexico or Central America, have been brought back by me from the 

 lower Rio Grande. The description of these new species, together with a 

 list of the species known to occur in that region, will be published by me 

 in the Bulletin of the Museum of the Brooklyn Inst, of Arts and Sciences. 

 The two following species are here described in advance, in order that 

 they may be included in the revision of the Ptinidae on which Prof Fall 

 is at work. 



The types are in the collection of the Museum of the Brooklyn 

 Institute of Arts in Sciences. 



Trichodesfna Texana, n. sp. — Cylindrical oblong, form of sordida, 

 black, twice as long as wide, with white and fulvous recumbent pubescence, 

 intermixed with longer erect hairs. Antennae brown, last three joints 

 longer than the preceding. Head black, densely granulated, pubescence 

 white, intermixed with fulvous. Thorax broader than long, sides arcuate 

 in front, sinuately narrowing to the hind angles, disc gibbous, hardly 

 sulcate at the gibbosity, surface granulate and densely clothed with white 

 and fulvous short recumbent hairs, intermixed with longer erect hairs, 

 gibbosity with four black spots, two at the summit and two below these, 

 no brush-like tufts. Elytra as broad as the thorax at middle, regularly 

 striate, with coarse, deep, closely-placed punctures, very densely clothed 

 with white recumbent pubescence, reaching nearly to the apex, terminated 

 by a few black spots ; apex sparsely clothed with fulvous pubescence. 

 Body beneath black, shining, with dense gray pubescence.- 



Length, 4-5 mm. 



Esperanza Ranch, near Brownsville, Tex. 



This species seems to be very near T. albina, Gorh.*, but, judging 

 from the description and figure, is distinct from it. All the specimens I 

 have laken are quite constant, except in the distinctness of the hind angles. 

 These are in some specimens distinct, and the sinuation before them is 

 very pronounced, in others the angles can be called rounded, in these the 

 sinuation is much less pronounced.
