MORGAN HEBARD 91 



Type. — 9 ; Pamplona, Santander, Colombia. Elevation, 7700 

 feet. May, 1916. From A. Maria. [Hebard Collection, Type 



No. 441.] " 



Size much smaller than in P. americana, close to that of penmana; body robust, 

 abdomen expanding and decidedly broadest meso-distad. Head with sutures 

 distinct but represented by mere lines, occiput smooth and convex. Eyes 

 small, much shorter than cheeks. Antennae with ten joints which are sup- 

 plied with very few microscopic hairs; first joint very elongate and slender, 

 nearly as long as width between antennal sockets; second joint minute, quad- 

 rate; third elongate, slender, three times as long as width, which is subequal 

 throughout; fourth twice as long as greatest width; succeeding joints increasing 

 in length and more slender distad, but all showing a weak convexity of the 

 lateral margins, not tubular as is the third. Pronotum subquadrate, sur- 

 face weakly convex proximad with a very fine medio-longitudinal sulcus; 

 lateral margins weakly cingulate and feebly diverging caudad; caudal angles rec- 

 tangulate, more broadly rounded than the rectangulate, sharply roundedcephalic 

 angles; caudal margin transverse. Tegmina represented by small, broad ovate, 

 lateral pads, extending very slightly beyond the caudal margin of the mesonotum. 

 Wings absent. Metanotum with caudal margin broadly concave. Abdomen 

 smooth, broadening to fifth dorsal segment, stink glands obsolete. Ultimate 

 dorsal abdominal segment broad, smooth, with a weak medio-longitudinal 

 sulcus becoming gradually heavier toward the caudal margin, along wliich 

 margin, between the bases of the forceps, is a narrow, transverse, depressed 

 area. Forceps heavy, triquetrous proximad, flattened distad and curving 

 weakly to the acute apex; internal margin with a heavy tooth just beyond end 

 of proximal third, succeeded by a few, irregular, decidedly smaller, blunt teeth. 

 Penultimate ventral abdominal segment with distal margin nearly rectangulate 

 with apex broadly rounded. Limbs elongate and slender. Caudal metatarsus 

 with ventral surface heavily supplied with hairs and with an internal and 

 external row of rather closely set spines,'' the external row not continued to 

 distal portion of joint. , 



Length of body, 15.6; head, 3.8; pronotum, 2.9; exposed portion of tegmen, 

 L8; forceps, 5.1; caudal femur, 4.3 mm. Width of occiput, 3.2; pronotum, 3; 

 tegmen, 1.4; lateral portion of tegmen, .8; dorsal portion of tegmen, 1; abdo- 

 men at fifth dorsal segment, 5.6 mm. 



^ Lacking an internal fringe of lamellae as found in Anisolahis maritima, 

 Euborellia annulipes and scudderi, or an internal fringe of very closely set hairs 

 as in Psalis americana and compacta and in Spandex percheron. The arma- 

 ment of the ventral surface of the metatarsus may prove a valuable generic 

 feature in the Psalinae. At the present time the genera Psalis, Anisolahis, 

 Spandex, Metalabis and Euborellia offer a number of vexing problems. With- 

 out a monographic study of this group we would hesitate to erect a new genus 

 for the present species with its distinctive metatarsal armament. When such 

 work has been done, however, it is probable that this and other features will 

 oblige generic separation.
