REVISION OF LISTROCHELUS SAYLOR 101 



were like several swarms of bees all in the air over one's head at once. 

 Many came to the light of the tent, but the great majority of them 

 seemed to be flying quite high. The flight lasted from about 8 until 

 9:30. The day previous had been rainy and heavy rains had fallen 

 the past four days. July 13: This fhght has continued to a greater 

 or less extent each night since the first record — last night there were 

 millions of the beetles in the air, and at times one could hardly remain 

 out of doors because of them hitting the person in the face. Tent 

 roofs and sides were fairly covered with them, and a large handful 

 at a time could be picked up. I am told that many are found in the 

 ground of the gardens hereabouts, and in fact I saw a great many 

 turned up in a garden at the packing house. There are no trees 

 closer than 3 miles from camp, and these are limited to scrub oak 

 and several species of pine. The range around is covered with 

 grama grass and weeds. Two classes of the latter predominate, 

 namely Gutierrezia sp. (brown-weed) and Artemesia frigida (worm- 

 wood, or sage brush). Many native lupines abound. The soil is 

 mostly' a sandy clay loam. An unusual amount of moisture has 

 fallen this season and it has been well distributed. To date it has 

 rained 29 out of 59 days since we arrived in camp." 



PHYLLOPHAGA (LISTROCHELUS) NEOMEXICANA. new Bpeclea 



Figures 2, j; 4, h; 11, e-g 



Male. — Apparently not different externally from L. koehleriana. 

 The male genitalia are distinct in the two species; the characters of 

 the genitalia do not vary in the rather extensive series of L. koeh- 

 leriavxi at hand. 



Female. — Unknown . 



Length. — 13-15 mm. Width. — 6-6.5 mm. 



Types. — Two males, both from Roswell, N. Mex., collected by 

 Brant on July 2. The holotype is in the United States National 

 Museum (No. 53767), and the paratype is in the Saylor collection. 



Remarks. — Though only the two specimens are at hand, the aedeagus 

 is so different from that of L. koehleriana that I have no hesitation 

 in describing L. neomexicana; reference to the genitalic figures will 

 allow of ready separation of the two forms.

 otherwise rufocastaneous, elytra pruiuose or opaque, above with
