270 THE CANADIAN ENTOMOLOGIST. 



simple oval glands. Mouth-parts large, yellowish. Dermis not minutely 

 wrinkled. Antennal formula (34) (12567) 8. 8 with some bristles, one 

 longer than itself. 



Hab. — On bark of branch of some woody plant, Salina Cruz, Mexico, 

 May 29, 1896. (Townsend : Div. Ent., >fo. i\()\.) L. radiatus is much 

 more depressed than quercus, not marked like dendrobii^ rounder than 

 acacice, differently coloured from eucalypti, darker, rounder and smaller 

 than rttfesceiis, darker and more distinctly radiately ribbed than yuccce. 

 It seems to be very near to Lecaniodiaspis atherospermce (Maskell), by its 

 small size, 8-jointed antenna, and very minute figure-of-8 orifices ; yet it 

 differs in some particulars, and is, I believe, not the same. Z. atherospermce 

 is from Australia, but it may not be a native of that country. Mr. Maskell 

 himself remarks that it is more like the neotropical dendrobii \\'\2i\\\\\Q 

 other Australian members of the genus. 



(8.) Conchaspis Newsieadi, n. sp. — $ scales crowded on the bark, 

 overlapping ; subcircular to oval, dirty white, low conical, diam. 2^ mm. 

 Apex sublateral, no radiating ridges. 



$ oval, orange-brown, similar to C. angrceci in most respects. 

 Antennas 6-jointed, joints subequal, variable. Femur longer than tibio- 

 tarsus, coxa about twice as broad as long. The round gland orifices with 

 cremate edges (so strongly crenate as to appear raoniliform) are very 

 distinct ; the hindmost segment that shows them is the fourth from the 

 end, this has a pair, close together, on each side. The next segment has 

 on each side four close together, one a little mesad of these, then two at 

 considerable intervals mesad. The next has on each side five in an 

 irregular row, and two pairs at considerable intervals mesad. The 

 next has five and one mesad. The details of the arrangement will differ 

 on the two sides of the same specimen. Long marginal hairs as usual in 

 the genus. Lobes at end of bod-y indistinct. 



(J scale similar to that of the 9 '" texture, but small and elongate. 



cJ Pupa red-brown, antennae stout, of about 7 joints, reaching be- 

 yond base of the large rounded wing-pads ; end of abdomen with a short, 

 stout caudal stylus, blunt at tip ; on each side of the last abdominal seg- 

 ment, by the base of the stilus, are three bristles, two very small, one 

 longer. 



Hab. — On Zuchil tree {P/u??iieria), Vera Cruz, Mexico, Feb. 26th. 

 (Townsend: Div. Ent., No. 7159.) I take the liberty of connecting with 

 this insect the name of Mr. R. Newstead, who, under the name of
