66 THE CANADIAN ENTOMOLOGIST. 



SO that they are not half as high as broad ; surface thrown more or 

 less into concentric folds ; colour bright orange ; median dorsal area 

 ferruginous, with radiating ridges and the usual orifices, the minutely 

 transversely ribbed larval exuvia in the middle. Young, up to about 

 2 mm. long, orange-ferruginous, with rather obscure radiating ridges. 



Second stage : female with the cephalothoracic end narrower than the 

 abdominal, and with a constriction between the thorax and abdomen. 

 Abdomen emarginate posteriorly, as in the same stage of T. Mexicana. 

 No spine found. A couple of pale ferruginous (chitinous) triangular 

 plates, each presenting near the middle a round patch of greatly crowded 

 and very numerous gland-orifices, each of which under a high power 

 exhibits a central nucleus, from which radiate five lines. Near one 

 corner of the triangular plate is a smaller patch of similar orifices, 

 here about twelve in number. Anal ring with ten long bristles ; the ring 

 is transversely oval, and is divided into an anterior and a posterior part. 

 The anterior part, bearing four bristles, is deeply notched in the middle 

 anteriorly ; the posterior part, bearing six bristles, is deeply notched in the 

 middle posteriorly. The lac is very hard to dissolve. The insects show 

 the usual crimson pigment. 



Hab. — Garoet, Java, Dec. 7, 1901, on grape-fruit (Citrus); collected 

 by Mr. C. L. Marlatt. The second-stage females are attacked by a 

 parasitic fungus, their bodies being full of the threads in some instances. 

 The adults show large parasite holes, and what the parasites have left 

 has been almost entirely consumed by a host of small hairy mites, 

 evidently a species of Tyroglyphus, as they agree well with Fig. 54 

 in Marlatt, Bull. 14, N. S., Div. Ent., Dep. Agr. (1898), p. 103. Owing 

 to these conditions I was unable to obtain a good specimen of the female 

 adult for mounting. 



The species is easily known from T. decor ell a by the absence 

 of ribbing beyond the second stage. 



A CONTRIBUTION. 



Mr. E. P. Venables, Vernon, B. C, thoughtfully considering the 

 needs of the Society, has donated to it some British Columbia beetles, the 

 most of which are new to its collection, thus increasing by so much its 

 powers of usefulness to others for the determination of specimens.
