A NEW GEOiMETRID GENUS, AND A NEW SPECIES FROM 



THE EXTREME SOUTHWEST. 



BY RICHARD F. PEARSALL, BROOKLYN, NEW YORK. 



(Continued from pag-e 332, Vol. XLII.) 



In continuing my paper, the title becomes doubly appropriate, for it 



is necessary to erect still another genus for the reception of a species, 



whose position would seem to fall between Pherne Hulst and Stenaspilates 



Pack., although it differs from these associated genera in having veins 6 



and 7 long-stemmed in secondaries. It is to be regretted that none of the 



examples before me is a cC , so that my diagnosis refers only to the 9 



form, but I seek to supplement it by pre- 

 senting a figure of the venation herewith, 

 and call the genus 



Apicrena, nov. gen. 

 $ . — Palpi long, beak-like, the terminal 

 joint long and drooping ; antennag long, 

 strongly pectinate to tips. Front loose 

 scaled, with conic hair-tuft above clypeus. 

 Tongue developed, thorax and abdomen 

 without tufts, the latter heavy. Fore 

 tibiae unarmed, hind tibiae long, slightly 

 swollen, with two pairs of spurs. Primaries 

 long, falcate at apex, margin doubly 

 crenate to vein 4, straight to anal angle, 

 12 veins, 10 and 11 from cell, 8, 9 and 10 

 joining beyond cell at a point, 11 barred 

 with 12 above cell, 6 and 7 from point, 3 

 and 4 separate. Secondaries rounded at apex, margin with a strong excision 

 between veins 6 and 4, vein 8 parallel to cell for half cell's length, 5 

 wanting, 6 and 7 long stemmed, 3 and 4 separate. No fovae present. 



Type Apic7'ena calca^'ia, n. sp. 



Expanse, 32 mm. All above white, more or less sprinkled with pale 

 chocolate scales, the primaries, thorax and head being quite evenly 

 coloured and darker, while the abdomen and secondaries are nearly white, 

 the latter thinly sprinkled, but shading slightly darker toward margin. 

 Along costa of primaries a few fine black scales are scattered, clustering
