220 THE CANADIAN ENTOMOLOGIST. 



wiicolor, Fh, ( = galbanata, Van D.), but is slightly larger and differs 

 widely in the form of the genitalia, both male and female. 



Chlorotettix breviceps, n. sp. 



Length, 6. 25 mm. Vertex not longer at middle than at eyes. 

 Ocelli black, scarcely farther than their width from the eyes. Colour 

 throughout pale brownisli ; two longitudinal whitish lines on scutel. 

 Last vental segment twice the length of preceding, hind margin very 

 broadly, slightly notched. Ovipositor about equalling pygofers. 



Described from two females in the Herbert H. Smith collection, 

 taken at Chapada, Brazil, in May. Nearest viridia, but the vertex 

 shorter, the ocelli smaller and further from the eyes, and the colour 

 different. This insect has somewhat the aspect of an Idioceriis. 



Chlorotettix minima, n. sp. 



Length, 5 mm. or slightly more or less. Ocelli large and very close 

 to the eyes. Vertex distinctly, though but little, longer at middle than 

 at eyes. Colour pale yellowish . Last ventral segment of female twice 

 the length of preceding, lateral angles broadly rounded ; medially with a 

 deep narrow notch, extending more than half the length ; the angles on 

 either side of the summit of the notch projecting obliquely towards each 

 other and sometimes nearly touching ; in one specimen these projecting 

 angles are nearly obsolete. Valve of male shorter than preceding segment 

 and scarcely angled at middle. Plates rounded basally at sides, beyond 

 middle becoming suddenly narrow and parallel-sided for rest of length. 



Described from one male and several females in the Herbert H. 

 Smith collection, taken at Chapada, Brazil, in April and May. The 

 smallest species of the genus yet described. The form of the ventral 

 notch varies, as it does in most species of the genus. In general form 

 the species recalls unicoior, Fitch. 



SOME NEW SPECIES OF COCCID^. 



BY J. D. TINSLEY, MESILLA PARK, N. MEX. 



Dactylopius Quaintancii, n. sp. 



Adult?. Length, 2 mm. Width, 1.5 mm. Shape, ellipsoidal, 

 much flattened. Colour, dark grayish-brown, the body is so covered with 

 white secretion that its true colour only shows on the ventral surface, 

 the colour of the dorsum appearing quite while. The white secretion 

 mealy, projecting slightly on the lateral margins, but not forming well- 

 marked filaments ; posteriorly it is produced into two very short, but 

 well-defined, caudal filaments ; on the dorsum it is slightly raised into a 

 longitudinal ridge.
