NOTES ON COCCID^ VI 



In Vol. Ill, No. 1, p.igc 108, the insect described as Eriococcus adenostomae 

 Elirliorn is Lecaniodiaspis rufescens Cockerell. 



On page HI the title and part of the description of Orthezia artemisiae 

 Ckll. were omitted by the printers and was as follows : 



Orthezia artemisiae Ckll. 



This insect (Fig. 143 B. P. C. Jr. Ent. Vol. Ill, No. 1., p. 406) was first sent 

 to the writer by Roy K. Bishop, Horticultural Commissioner of Orange county. 

 Since that time I have obtained it in the vicinity of Santa Paula. 



The long wliite egg sac makes it at once conspicuous and easy to detect. It 

 occurs in great numbers on the California sage {Artemisia californica) during 

 the later summer months. That it never increases to any damaging numbers 

 may be explained by the fact that it is parasitized by a dipterous insect which 

 is an egg feeder. In some dozen females I was able to obtain several of the 

 puparia, but was not fortunate enough to hatch out an adult fly. 



In describing this coccid, I can do no better than to duplicate here, Cocker- 

 ell's original description, which is as follows: 



"Orthezia artemisiae n. sp. Female: Immature form. Antennae and legs 

 piceous. Body covered with white secretion. Dorsum with two rows of denti- 

 form tufts ; the first four directed forwards ; the remaining seven, decreasing 

 in size caudad, directed backwards. Nine lateral tufts; the first on a level with 

 the second dorsal tufts, at right angles to the body ; the others directed back- 

 wards, and about of equal length, except the last two, which are longer and nar- 

 rower, the last being longest. Caudal tufts extending caudad of last lateral 

 tufts. 



"Mature Female: Differs by having the lamellae or tufts much elongated, 

 the first dorsal erect, longer than broad ; the remaining dorsal produced and no 

 longer dentiform. The arrangement is now practically as in adult O. urticae 

 (L.), except that the first dorsal lamallse are smaller (instead of larger) than 

 the third. The hindmost lateral lamellae are also somewhat less produced than 

 in urticae. Antennae and legs red-brown ; antennae eight-segmented, three 

 longest; five a little longer than four; six and seven about equal, and shorter 

 than four; eight about as long as five. Length of insect, without ovisac, S^/o 

 mm. Ovisac moderate, white, distinctly ribbed." 



"0. artemisae is nearest to 0. annae, but the latter has the lamellae less defi- 

 nitely formed, and differs also in the antennas." Can. Ent. XXX. p. 19-20, 1898.
