Giglio-Tos' reason for assigning hiUneata to synonymy under lactea 

 and then describing a new species, sumatrana, is certainly not clear. 



Sandakan, British North Borneo, (from C. F. Baker), 1 cf • 



Labuan Island, British North Borneo, 3 cf . 



When compared with alhella, males of fragilis are seen to agree 

 closely, differing from those of that species only as follows. Inter- 

 rupted dark line margining pronotum and mesal pair of dots nor- 

 mally well defined, particularly on the collar.^^- Tegmina and wings 

 distad with outer portion of marginal field almost opaque and strik- 

 ingly buffy or reddish. Supra-anal plate triangular with apex 

 acute, length slightly greater than proximal width. Cerci shorter, 

 distal joint flattened \vith apex rounded, slightly broader than the- 

 preceding joints. 



We regret that no females of this species are before us. 



Leptomantis lactea (Saussure). 



1870. M{iopterijx] lactea Saussure, Melang. Orth., I, p. 274. [9 ; Manila,. 

 Philippine Islands.] 



Mount Makiling, Island of Luzon, Philippine Islands, (from C. F.. 

 Baker), 1 9. 



The specimen at hand has the body much discolored and shows; 

 no dark markings on the pronotum, as did specimens in Saussure's- 

 series, other than the type. Such a condition would appear to 

 occur also in albella and fragilis. The specimen under considera- 

 tion is slightly larger than Saussure's type, in other respects agreeing 

 fully. The tegmina and wings are weakly milky, the outer portion, 

 of the marginal fields distad being slightly more 80.^= When com- 

 pared with females of alhella, the present female is seen to be larger 

 with pronotum distinctly heavier, its lateral margins minutely but 

 distinctly denticulate, not smooth as in that species. The measure- 

 ments of this specimen are: length of body 35, length of pronotum 

 13, least width of pronotum 1.3, length of tegmen 21, width of teg- 

 minal marginal field 1.2, length of exposed portion of wings when at 

 rest 4.7, length of cephalic femur 7.8 mm. 



Leptomantis tonkinse new species. (Plate I, figures 11 and 12.) 



This species is apparently nearest L. indica Giglio-Tos, but so 

 poorly is that species characterized that the degree of affinity can 

 not be satisfactorily determined. 



'^ Apparently these markings are sometimes absent, possibly due to dis- 

 coloration. Westwood makes no mention of this feature in describing the type 

 of fragilis, but describes it in full for the type of bilineata.
