90 Ur'ii, 



formed ; fig. 1 on the plate represents an antenna of this character, 

 the true condition is shown in the margin ahove. 



The species belongs to Signoret's 4th section of the genus, which 

 includes L. hihernncidorum, cojfece, hemisplitericum, &c. 



One of the stems of Combretum was closely covered with a tough, 

 silky web which a Lepidopterous larva had formed over the adherent 

 scales of Lecania ; it had probably fed on the bodies of the insects, 

 for the scales were reduced to small fragments. In a cocoon of the 

 silky material was a pupa, but it was dead. Is this another cocco- 

 phagous species ? {cf. Ent. Mo. Mag., vol. xxiv, p. 225). 



Lecanium distinouesbum, n. sp. 



? adult. Oval, slightly attenuated and pointed posteriorly, the form frequently 

 irregular and the size less than the dimensions given below ; convex, smooth, shining, 

 brown, indistinctly and irregularly mottled with whitish ; ultimately a median lon- 

 gitudinal carina is developed on the abdominal portion, with three or four deep foveae 



on each side of it. Legs and antennae atrophied. 



Length, 5, breadth, 3, height, 2'5 mm. 



In the immature state, that is just before oviposition, broad-oval, flat-convex, 

 light reddish, a transverse line on the first third, a large median blotch posterior to 

 it, and a long blotch on each side of this, white. Antennte (fig. 4a) of 7 joints, taper- 

 ing ; Ist short and wide ; 2nd shorter ; 3rd very long, nearly as long as 4-7 together ; 

 4th and 5th much shorter, subequal ; 6th about the same ; 7th a trifle longer than 

 6th, with a few stiff hairs at apes ; the 3rd, 4th and 5th deeply notched on inner 

 side. Legs (fig. 4b), tibiaj but little longer than tarsi, the latter with two long, and 

 claws with two short, digitules. In a few days the scales collapsed, the colour became 

 red-brown, and the light markings disappeared; yet the bodies were full of un- 

 extruded eggs. In a still earlier stage the form of the scale is more regularly and 

 narrower oval, almost pointed at each end. 



(J adult. Scale white, glassy, of the ordinary Lecanium form. The imago of 

 the ordinary character, bright pieeous ; wings pale, the apical half of the costa 

 carmine. Legs fuscous, hairy. Antennte (fig. 4c) of 10 joints, with sliort, stiff, pale 

 hairs, on the last joint three of the apical ones clubbed. Length, lo mm. 



Larva ochreous ; antennae of 6 joints ; the 3rd, -1th, 5th and 6th with one 

 specially long hair, the 6th also with one more very much longer than any on it or 

 the other joints ; the tarsi and claws with the usual digitules. 



A pale median dorsal blotch is usually to be seen on the young $ scales of 

 several species of Lecanium, e. g., L. pyri, Schrk., L. tiliis, Linn., L. variegatum, 

 Goethe, &c., but I have not observed the other pale markings herein noted, nor seen 

 them described, in any other species except L. fuscum. Yet, as I regard such 

 evanescent markings as incidents and signs of immaturity, some or all of them may 

 be of general occurrence, but not noticed, because the scales are not observed in the 

 young state.
