longitudinal series of wartlike white prominences. Viviparous (ovoviviparous), the 

 young leaving the egg before being excluded from the body of the parent. 



Legs and antennee dark brown, the distal margins of the antennal joints broadly 

 pallid. Antennae ii-jointed, slender, joints i, 2 and 11 subequal in length and 

 longest, the others subequal and shorter, 3 about as long as troad; 4 and 5 shorter 

 than 3 and broader than long, 5 shortest ; 6 to 10 longer than broad. 3 may be as 

 long as 2. Femur rather stout. Tibia longer than femur. Tarsus curved, about 

 half as long as tibia. Claw pallid, broad, narrowing to a point. Mouth parts small. 



Larva at period of hatching i mm. long, bright red, sparsely powdered with white 

 meal, legs and antennae black. Antennre 6-jointed, 6 much longest; formula 6(21)* 

 3(54). End of body with 6 long hairs on each side, of which the first three and last 

 are about equal, and the other two very much longer. The two especially long ones 

 are very close together. 



Habitat: Mescalero Reservation, a short distance below the 

 Agency, at base of stems of Gntierrezia sarothrcs, October 2. Orthezia 

 nigrochicta Ckll., occurred in numbers on the same plants. On July 

 26, 1S92, Prof. Tovvnsend found a single specimen q>{ Jcerya on Gntier- 

 rezia tnicrocephala about 10 miles south of Navajo Springs, Arizona. I 

 did not see the specimen which was sent to Dr. Riley, but it was very 

 possibly /. townsendi. 



A tew weeks ago Prof. Townsend discovered at Mesilla an Icerya 

 on stems of PliicJiea borealis, while collecting PJienacocciis heiianthi, 

 which abounds on the same plant. This is larger than /. to^vnsendi 

 (long. 6.5, lat. 5.5, alt. 5 mm.), dark purplish grey, speckled with 

 white secretion, with very distinct longitudinal rows of yellow-white 

 mealy protuberances. These wart-like protuberances number about 8 

 in the dorsal row ; the sublateral row is anteriorly single, of three, then 

 giving way to two rows, of about 6 each. There is also a lateral row of 

 about 9. The legs and antennae resemble those of tozvnsendi. On 

 breaking open the body, I found a quantity of orange-yellow fluid, in 

 which the larvae had not yet reached the hatching stage, and so could 

 not "be compared with those of townsendi. This Icerya on Pluchea I 

 propose to call /. townsendi var. pluchece, as its characters scarcely war- 

 rant us in regarding it as a distant species. /. tozvnsendi is closely 

 allied to /. roscB; and especially, it would seem, to /. aiistralis, which 

 Maskell regards as a variety of rosoi. 



It may be remarked here that Icerya {Froticerya) rileyi Ckll,, 

 was found in abundance on mesquite a few miles south of Tularosa ; a 

 new locality. 



Dactylopius dasylirii, sp. nov. 



9. Length 4 mm. or slightly less, dark olivaceous, covered with white meal.
