44 THE CANADIAN ENTOMOLOGIST. 



some larger gland-orifices scattered here and there in this area. The 

 skin, in the places where it is colourless, is minutely granular. In the 

 sublateral ventral regions is a considerable quantity of short, light, 

 reddish-brown hair. I find no compound glands, such as exist in /. 

 Etiia7-ti. 



Hub. — Campinas, Brazil, May 12, 189S, on Mimosa (?). {A. Hempel, 

 215 d.) 



Mytilaspis banibusicola, n. sp. — 9 • Scale a little over 2 mm. long, 

 very narrow, of uniform width, rather convex, white ; with dark sepia- 

 brown exuviae, which are sculptured in a cancellate manner. After boil- 

 ing in liquor potassae, the scale dissolves to a milky substance, which 

 consists of fragments of minute moniliform threads. 



$ . Greatly elongated ; four rounded produced very distinct lobes, 

 all wide apart, the median ones the larger; in the interval between the 

 lobes a short bifid process ; immediately laterad of each median lobe a 

 very long gland-hair or squame, nearly twice as long as the lobe ; a 

 similar squame a short distance beyond each second lobe, and three 

 more at long intervals on the margin beyond. Beyond the second, third 

 and fourth squame or gland-hair the margin in each case presents two 

 obtuse elevations, not always very distinct. No groups of ventral glands, 

 but many pairs of transversely elongate gland-orifices scattered over the 

 pygidial area. Embryos in 9 very large. 



Hab.- — Campinas, Brazil, May 12, 1898. On stem of bamboo, with 

 Asteroiecanium bambtisce, Boisd. {A. Hempel, 215 c). M. bambusicohi, 

 by the absence of circumgenital glands, etc., approaches M. striata, 

 Maskell. The brief preliminary description published by Green of his 

 M. e/o?igata is rather suggestive of our species. Fortunately, I have some 

 M. eloiigata from Mr. Green, found on leaves of Arj/tidinara, at Pundu- 

 loya, Ceylon. The insect is now doubtfully referred by Green to Chion- 

 aspis, and it may well go there, having a Diaspis-Wkt ^ scale, with a 

 vaguely indicated keel. The $ scale will easily be known from bam- 

 busicola by its light orange-brown exuviae. 



The following species of Mytilaspis will be published in the Revista 

 do Museu Patilista (Brazil), but it is desirable to present an abstract of 

 the characters in an entomological journal : 



Mytilaspis argentata, n. sp — $ scale about 2^ mm. long, often 

 curved, very narrow — linear, in fact — but covered and broadly margined
