and yellowish; ventral scope shining cream-colour; wings strongly

 pical more or less cuneiform mark; middle tibiae with a yellow mark 

 extending from before middle to apex; hind tibiae with a yellow 

 band, interrupted not far from base; tarsi ferruginous, more or 

 less blackened at base, their hair mainly ferruginous; hind basitarsi 

 with a broad yellow band; no pulvilli; first abdominal segment 

 with a diamond-shaped yellow mark at each extreme side; second 

 segment with a larger mark on each side, deeply notched inwardly, 

 and a pair of transverse, discal stripes; third segment w'ith an

This has nearly the face-markings of A. porterm persomdatum 

 Ckll., but persomdatum is considerably larger, the spots at side of 

 face are lower down, the abdominal markings are much paler, and 

 the abdomen is not so densely punctured. I asked myself whether 

 A. wallisi could possibly be a colour-variety of A. tenidflorcB Ckll., 

 but it differs as follows, aside from the colour-markings: eyes paler 

 and lighter green; teeth at lower corners of clypeus larger, nearly 

 equal (the outer one much smaller in tenniflorce) ; lateral tooth-like 

 angles of sixth abdominal segment very prominent ; broad depressed 

 apical margins of abdominal segments excessively, minutely and 

 densely punctured, not shining (shining and less densely punctured 

 in teniiiflora). 



PHENACOCCUS BETHELI AGAIN. 



BY T. D. A. COCKERELL, BOULDER, COLORADO. 



When recently describing P. betheli in The Canadian Entomo- 

 . logist, I remarked that it was possibly a subspecies of P. cockerelli 

 King. I was surprised, a few days ago, to receive from Mr. E, 

 Bethel a quantity of P. betheli on branches of Amelanchier, collected 

 by Mr. L. J. Hersey at Steamboat Springs, Colorado. This looked 

 suspicious, as Steamboat Springs is the type locality of P. cockerelli. 

 However, the new material is twice the size of cockerelli, and yet 

 the legs are not merely relatively, but actually smaller, and the 

 fourth antennal joint is very short as in the Grand Canon insect. 

 The insects, on being boiled in caustic potash, stain it a deep wine 

 red. The larva is light orange. 



Although I transmitted the original cockerelli material to Mr. 

 King, I did not study it. I have, however, studied abundant 

 material, agreeing with King's description, found by Mr. L. C.
