126 PRELIMINARY LIST 



Dactylophis solani Cockerell. Det, Cockerell. 



Forh Collins, Ane^ust 23d on roots of Solannm rostratum 

 (Baker). Questiona-bly this species on the crowns of sugar 

 beet roots at Grand Junction, August 26th (Gillette). 

 Kernies galliformis Eiley. Det. Cockerell. 



Manitou, November 27th on Quercus undulata (Gillette). 



Kermes gillettei Cockerell. 



"Scale of female 8 mm. long, 7.5 broad, 7 high. Distinctly segmented: dorsum with 

 rounded tuberosities, not very shiny. Scale covered with minute dark brown specks. 

 General color ivory-wliite and dark brown mottled, the extent of the white or tlie brown 

 variable, but usually a distinct white dorsal band, and more or less brokeii-up subdorsal 

 ones- Derm by transmitted light reddish brown, with large oval gland-pits. Young larva 

 very elongate, subfusiform. with the greatest breadth anterior to the middle; pale 

 purplish pink. Caudal tubercles large and broad, each presenting two stout bristles, of 

 which the inner fmesad) one is much the shortest. There is also a moderately long bristle 

 on the outer side of each tubercle, near its base. Segmentation distinct; each segment 

 with a short spine or bristle on lateral margin. Antennae cylindrical, hardly at all 

 tapering, 6-,iointed; 3 and 6 equal and longest; 4 and 5 equal and shortest, these being 

 about as long as broad ; 2 very little longer than 4, and very much siiorter than 3; H almost 

 as long as 4 plus 5. Last joint rounded at the tip, bearing several hairs. Antennae color- 

 less. Rostral loop extending beyond base of third pair of legs. Mentum at least two- 

 jointed. Legs quite ordinary. Claws long, sharp, and a little curved. Tibia short. 



Hab. Manitou, Colorado, U.S.A., on twigs of Quercus undulata. Collected by Prof. 

 C. P. Gillette. Very distinct from K. galliformis, Riley, the only Kermes hitherto 

 described from North America. Its nearest ally is evidently Kermes gibbosus, Signoret, 

 which was found on oaks near Vienna. 



The larvae described above were found inside the scale of the female." 



We copy the above from a separate of Mr. Cockerell's 

 paper in " The Entomologist," which bears no date. The 

 practice of publishing original descriptions of single 

 American species in foreign journals which are to a large 

 extent ina^cessil^le to American entomologists, cannot be 

 too strongly condemned. 

 Physokeruies coloradensis Cockerell. 



"Female scale with the same general shape as P. abietis and attached in f lie same 

 way to the twigs. Diameter 7 mm., smooth, shiney, rather pale brown, inflated, subreni- 

 form, with a median constriction. Derm yellowish brown, reticulate, the reticulations 

 hexagonal. Large gland-pits looking like perforations. Mouthparts small, rostral loop 

 short. Legs not to be found, apparently absent in the adult. Antennae small, six- 

 jointed, but tho .ioints obscure. Last joint with several hairs. Joints subequal, except 

 the second and fifth, which are shorter; the second shortest, bearing a long hair; fourth 

 perhaps a very little longer than third, and longest; fifth constricted, simulating second 

 joints, the second of them shortest. 



Habitat Manitou, Colorado, November 2f)th, 1894, on Pinus edulis. Collected by Prof. 

 C P. Gillette. It is attacked by a brownish Ohalcidid parasite. 



From European P. abietis it is distinguished by its size and by the antennae. No 

 species of the genus has hitherto been found in America." 



This species was described in "The Entomologist" with 

 the preceding species. A spruce should have been given as
