644 REVISTA CHILENA DE¡ HISTORIA NATURAL 



(Lám. LXXIV, E) eutire, iu sorae specimens not visible, 

 being covered by the sub-marginal papillae. Sub-margiual 

 papillae rouiided atthe apex, slightly chitinized, so closely 

 set together that they join each otlier. Dorsum iinraarked, 

 abdominal segments distiuct. Vasiform orifice (Lám. 

 LXXIV, F)siib-cordate, elongate, cephalic margin straight, 

 the caudal portiou of the oriñce crossed by many reticulate 

 Unes; operculum of the same shape as orifice, bluntly 

 roimded at the caudal margin, filling one-half of the orifi- 

 ce; Úngula with four, indistinc lobes, setose and with two 

 small setae arising from the caudal lobes. A pair of long 

 setae are found on the caudal margin of the case. 



Adults. UnknoAVu.

Trialeurodes sliawiindiis, n. sp. 



There is only one slide of this species in the Bureau 

 coUection, Avith many individual pupa cases on that slide. 

 The material was collected in Chile on an unknoAVu 

 plant. 



Pupa case. (Lám. LXXIV, Fig. G.) Size; 0.72 mm. in 

 length, 0.48 mm. in width; light yelloAV iu color with 

 tinges of orange. Margin (Lám. LXXIV, H.) slightly cre- 

 nulate, Avith eveu, shallow teeth; from each tooth exten- 

 ding mesad 0.03 mm. is a shalloAV groove, mesad of each 

 marginal tooth is a small sub-marginal papilla. Dorsum 

 marked with light reticulate Unes, a roAV of small setae 

 arouud the entire dorsum, just mesad of the sub-marginal 

 área. Vasiform orifice (Lám. LXXIV, I) sub-cordate, elon- 

 gate, Avith cephalic margin straight, lateral margins thic- 

 kenedand chitinized; operculum sub-cordate, filling one- 

 half of the orifice. Lingula setose, twice lobed, Avith tAVo 

 long setae arising from the caudal lobes; abdominal seg- 

 ments distiuct Avith six small papillae in a Une along the 

 lateral extremities of the abdominal sutures, and one on 

 either side of the cephalic portion of the vasiform orifice. 

 Candad of the orifice and 2.01 mm. from the margin are 

 two small setae. 



Adults. UnknoAvn.
