THK CANADIAN KNTOMOLOGIST. 27 1 



Pseudingiista, has given us the best account of Conc/iaspis yet published. 

 With Mr. Green's Ceylon C. sociaiis, this will make the third species of 

 the genus so far discovered. The ^ pupa, now described, is very inter- 

 esting, as it is just like the pupa of a Diaspid. 



(9.) Llaveia axiniis (de la Llave). — Prof. Townsend found at .Salina 

 Cruz, on May 27lh, specimens of a large monophlelid, which I believe is 

 identical with the imperfectly described LI. axhius. The specimens are 

 red, with mealy powder, and are sparsely marked with small black spots ; 

 dried specimens appear more grayish, and look something like very large 

 Coccus cacti. The legs and antenna; are red-brown, the inner side of 

 tibia and tarsus presents a row of short spines, about 1 1 on anterior tibia, 

 and six, very small, on anterior tarsus. There are two rows of longer 

 spines on the under side of the femur. Dermis rather thickly beset with 

 short hairs. The largest specimen sent to me is perhaps not adult, and 

 has only nine-jointed antennae. Its dimensions are, long. 13 mm., lat. 

 65^, alt. 4^^ mm. It appears, however, that adults were certainly found 

 by Townsend, as among the material received at Washington were both 

 eggs and young larva;. Dr. Howard has kindly lent me a mounted 

 larva, from which I have made the following description : 



Larva oval, bright red, beset with short, rather stout spines. .Seven 

 very long hairs on each side of hindmost half of body, one to each seg- 

 ment, each accompanied by a much shorter and more slender hair, the 

 smaller hair on the penultimate segment longer than its representatives 

 on those anterior to it, and about half as long as the long hair of the 

 same segment. The long hairs of the caudal segment accompanied by 

 two smaller hairs, of which the innermost are the longest. Legs long, 

 femora moderately stout, those of front legs about as long as tibia, of 

 hind legs shorter than tibia. Tibia and tarsus very slender ; tarsus of 

 front legs equal with tibia, of middle legs a little shorter, of hind legs con- 

 spicuously shorter than tibia. Claw long, little curved. Eyes very 

 dark, subconical. Antennae 6-jointed, last joint or club very large, much 

 swollen, longer than 4 + 5, with three whorls of hairs. Second joint a 

 little longer than third, 3 and 4 equal, 5 shortest. The joints from i to 4 

 might be called subequal, and the formula then written 6(2134)5. 



I am inclined to suppose that Llaveia and Ortonia will prove to be 

 the same genus, differing at any rate not mor^ than do species novy 

 included under Icerya.
