HALYZIA.— PSYLLOBOEA. 165 



sutural one of the succeeding three is hooked outwardly and recurved towards the 

 base on the sutural side — this spot is usually detached from the suture, but in one 

 example it forms a common pear-shaped spot on the suture. 



We have received three examples of this species, two of them being from San 

 Geronimo. A specimen from each locality is figured ; the one from Panama is rather 

 smaller than the Guatemalan representatives. 



3. Halyzia championi. (Tab. X. fig. l.) 



Oblonga, lsete, dilute flava ; prothorace quam elytra multo angustiore, basi punctis duobus nigris lateribus 

 modice explanatis et reflexis, subdiaphanis ; elytris creberrime minute punctatis, singulis punctis novem, 

 2, 3, 3, 1 dispositis, nigris. Long. 4| millim. 



Hab. Panama, Volcan de Chiriqui 8000 feet (Champion). 



The sides of the thorax converge towards the front, but are considerably rounded at 

 the hind angles ; the front margin is almost straight, and the head can be retracted at 

 least as far as to hide the eyes beneath it ; the base is sinuous, and is marked with two 

 round dots (like those in the Eastern Thea cincta), and this character alone will distin- 

 guish H. championi from any Halyzia known to me. Of the elytral spots, two are near 

 the base, one of them being on the humeral callus, and one between it and the suture ; 

 then three almost in a straight row, but the inner one a little nearer the apex than the 

 others, then three in a chevron ; and one subapical small dot. In the number and 

 position of the elytral spots the species resembles Neohalyzia perroudi. 



Only one example of this pretty Halyzia has been found, which I dedicate to its 

 captor, Mr. G. C. Champion. 



PSYLLOBORA.

Psyllobora is, as Crotch has remarked, the New-World representative of Thea. It is . 

 simply a convenient geographical division, several species of Thea, e. g. T. variegata (from 

 St. Helena and Africa) &c, being absolutely conformable to the type of Psyllobora, 

 and some others having the expanded margin of typical Halyzia. The Psyllobora? are, 

 however, generally to be distinguished by the style of marking ; and among them are 

 found the smallest species of Coccinellidae, not exceeding the smaller Scymni in stature. 

 About forty species are recorded by Crotch, chiefly from the South- American continent, 

 one or two species only being found in the United States. 



According to Mr. Champion some of the Psyllobora? are found commonly on 

 orange-trees.
