 Ameles malaccana n. sp. 



Type: 9; Trong, Lower Siam. (Dr. W. L. Abbott.) [Cat. No. 

 6,955, U. S. N. M.] 



This species is probably related to A. abjeda Cyrillo { = spallanzania 

 Rossi et auct.) and A. decolor Charpentier of southern Europe. While 

 quite distinct from either of these forms, no satisfactory comparison 

 can be made without good figures or accurate descriptions, and as the 

 existing ones are based chiefly on the males, no comparative diagnostic 

 characters can be given. The central Asian A. alata Saussure is an 

 entirely different insect, the female having wings as long as the body. 



Size rather small ; form rather robust, abdomen moderately ex- 

 panded. Head very slightly broader than deep; vertex subtruncate, 

 juxta-ocular lobes rounded; eyes ovate when viewed laterally; ocelli 

 disposed in a small triangle ; facial shield moderately transverse, the 

 superior margin very slightly arcuate.' Pronotum over twice as 

 long as broad; collar broad and gradually expanding into the 

 rather well-marked, but evenly curved, supra-coxal expansion; 

 shaft contracting posteriorly; surface with sparse tubercles, median 

 carina slightly marked on the shaft, at the posterior margin flanked 

 l:)y a pair of moderate-sized blunt tubercles ; margins, except 

 the anterior and posterior, with rather even, short dentiform spines. 

 Tegmina very short, not equal to the pronotum in length ; apex obtuse, 

 narrowly rounded. Wings very slightly exceeding the tegmina in 

 length. Abdomen sub-fusiform, the apex rather strongly constricted, 

 the whole bearing a distinct dorsal median carina. Supra-anal plate 

 transverse, the apical margin subrotundate. Cerci not exceeding the 

 subgenital plate in length, depressed. Subgenital plate large, apex 

 rostrate', compressed. Anterior coxae very slightly longer than the 

 pronotum, the lower margin finely denticulate ; femora slightly longer 

 than the pronotum, very heavily built, external margin bearing five 

 large spines, one of which is blunt and apical, internal margin bearing 

 thirteen unequal spines, discoidal spines three in number; tibiae very 

 slightly more than half the length of the femora, the external margin 

 bearing nine spines, the basal ones much smaller than the apical, the 

 internal margin bearing eight spines, the basal ones smaller than the 

 apical; metatarsi slightly exceeding the remaining tarsal joints in 

 length. Median limbs slender, tibiae shorter than the femora, the 

 metatarsi not equal to the remaining tarsal joints in length. 



General color dull umber, obscurely and irregularly spotted and
