A NYCTERIBID FROM A NEW MEXICO BAT. 

 H\ C". H. In IKK lOwNSKM). 



The following Nycteribid was taken from the breast of a bat 

 caught in Las Cruces, N. Mex., Oet. 5, 1891. It proves to belong 

 to the genus NycferiHa in the restrictetl sense. 



Osten Sacken says, in the 1878 edition of his catalogue, that 

 no North American species of lyycfiril'ia had u\) to that time been 

 described, but that the Museum of Comparative /oology in Cam- 

 briilge possessed a specimen of this genus from California. Since 

 1S78, Mr. Bigot has ilescribed a species from Mexico, which he 

 called \. iiiiwiiaiia (.Ann. Soc. Knt. Fr. 1885, p. 245). I am 

 unaware that any other North American species has been de- 

 scribetl. The present form is distinct from Mr. Bigot's species, 

 and may be recognized by the following description. 'I'he species 

 of bat upon which it was found has been determined by Dr. C. 

 Hart Merriam as Aiitrozoiis falliiitis. Dr. Merriam writes that the 

 type of this bat " came from Kl Paso. Texas, whence the species 

 ranges west to California."' 



Nycteribia antrozoi n. sp. 



Drownish yellow, legs paler; claws l^lack, bristles reddish brown. \Vliole body, 

 both ventrally and dorsal ly, and legs more or less covered with short bristle hairs, 

 also some longer bristles. He.nd thrown back, the disial 01 al region bearing a 

 gioup of short hairs and two long ones. 'Jlie pair of long hairs appears to arise 

 from the palpi, one from each palpus, and ihey are hardly three times as long as 

 the longest of the other hairs on the oral margin. 'Ihora.x broad ; its ventral as- 

 pect wide, flat, abruptly sloped off posteriorly, very evenly rouniled anteriorly, 

 with a longitudinal median suture; a lateral diagonal suture running posteriorly 

 outward at an angle of 45 degrees ficm the median suture, starting from latter a 

 short distance from anterior margin. Abdomen broad at base, tapering to a rather 

 truncate apex, composed apparently of four segments, the anal segment much the 

 longest and rather triangular in shape. Dorsum of next to last segment c|uite 

 circular on hind border; (he posterior border of each segment fringed with short 

 bristles, the second and third segments also with some stronger and longer mar- 

 gin:il bristles approaching niarcrochastx; on each side of middle. Last segment 

 with three or four marginal bristles of equal length on each side, but without any 

 longer bristles, the longest shorter than the bristles on margin of third segment. 

 N'entral aspect of abdomen different from dorsal; a compact even transverse row of 

 short strong posteriorly appressed black spines at base of venter; segments two 

 and three with marginal bristles, but not long ones. There is an anal pair of 

 elongate chitinous bristly appendages, which are bent forward beneath the abdomen 

 to which they are closely appressed, extending beyond posterior margin of third 

 segment, tapering to tips which are black. Legs of about equal length; the
