THE CANADIAN ENTOMOLOGIST. 263 



Cladobius Beulahensis, n. sp. — Winged '^ : Rather large, robust ; 

 head and thorax black ; abdomen grayish-brown, dorsum with a broad, 

 dull black band on each segment, sides with large black spots ; on the 

 first four segments there is a considerable interval between the bands and 

 the spots ; ventral surface of abdomen immaculate, except that the last 

 segment bears a large transverse black spot ; insect thinly clothed with 

 short hairs ; legs very hairy, dark ferruginous \ knees, end of tibiae, and 

 tarsi black ; wings ample, hyaline, not darkened along the veins, stigma 

 large, grayish-brown, fork ample, but shorter than its stem ; antennas 

 reaching second abdominal segment, blackish, third segment ferruginous ; 

 Cauda broad and rounded, hairy, not produced ; nectaries short, distinctly 

 swollen, ferruginous, black at apex, very much longer than broad ; beak 

 reaching posterior margin of middle coxfe, or at least their base. Length 

 of insect, 3}4-3/4 mm. Measurements in /x : Antennal joints, (3) 500, 

 (4) 260-290, (5) 250, (6) 170, (6b) 310. Nectaries about 250. The 

 prothorax has a lateral tubercle. 



Young dark gray, slightly purplish.; femora dull whitish. 



Beulah, New Mexico, prox. 8,000 ft., Aug. 4, on Popidus tremuloides, 

 in little colonies (winged and young) on the twigs. The leaves of the 

 tree were much curled, I suppose by the aphides. Related to C. btcolor, 

 but not identical ; also clearly distinct from C. salicti. By the banded 

 abdomen it resembles C. piiosns (Pterocomma pilosa, Buckton), but it is 

 not the same. It is not C. saiicis, and it is certainly not C. populeus, as 

 that insect is figured by Buckton. There seems to be some confusion 

 about C. popiileus (sometimes called popidiieiis) ; it has been recorded 

 from Greenland (Riibsaamen) and Alaska (Pergande), and might be 

 expected in the Rocky Mountains,* but so far as I can make out our 

 insect is quite distinct from it. 



Aphis tnedicaginis, Koch. — Abundant at Pecos, New Mexico, on 

 Glycyrrhiza lepidota. Some were found on Sphceralcea Fetidieri growing 

 near the Glycyrrhiza. 



Lachnus vimifialis (Fonsc.) =dentatics, Le Baron. — Pecos, New 

 Mexico, 1903, on Salix. New to New Mexico. 



Chaitophorus negundinis, Thos. — Pecos, N. M., 1903 (Dr. M. 

 Grabham). C. populicola, Thos., was also found at Pecos. 



Thirty-eight AphididcC are known from New Mexico so far. 



*The willow-coccid Eriococcus borealis, described from Dawson City, N.-W. T., 

 has since been found by me at Beulah, New Mexico.
