140 THE ENTOMOLOGIST. 



Atoyac in Vera Cruz during May, and has the metathorax 

 transaciculate, not " deeply punctured," as Cresson describes 

 it ; the basal nervure is continuous. It was originally brought 

 forward upon a single female collected in Comal Co. 



6. JOPPIDIUM FUSCIPENNE, Brull6. 



Cryptus fuscipennis, Brulle, Nat. Hist. Ins. Hym. iv. 1846, 

 p. 189, female;- c/. Cam. Biologia Centr.-Amer. 1885, 

 Hym. i. p. 211. J. yucatanense, Cam. lib. cit. p. 211, 

 pi. ix. fig. 18, female. J. donahilis, Cress., Proc. Acad. 

 Philad. 1873, p. 139, male and female. 

 No doubt can, I think, be experienced that Brulle's descrip- 

 tion refers to J. donahile, and it was placed in the present genus 

 by Cameron in 1885 ; the metathorax is rather transaciculate than 

 " rugueux," but the "deux chevrons paralleles" are obviously 

 the two transcarinae, which are often centrally incomplete. It 

 is an abundant Mexican species, found by Sumichrast at Cordova ; 

 subsequently described from a single female as new by Cameron 

 from Valladolid in Yucatan (this type differs from the usual 

 form of J. donabile only in its paler — by no means whitish, as 

 figured— flagellar base). I have examined eighty examples, 

 among which the male much predominates, from Venta de 

 Zopilote at 2800 ft. in October, Chilpancingo at 4600 ft. in July, 

 Temex in northern Yucatan, Cuernavaca in Morelos in June, 

 Acaguizotla at 3500 ft. in October, Guadalajara in Jalisco in 

 July, and Dos Arroyos in Guerrero at 1000 ft. in September. 

 This and J. ccsruleipemie are the only Mexican species with 

 entirely rufescent thorax and unicolorous wings. 



7. JOPPIDIUM BELLICOSXJM, Hal. 



Cryptus bellicosus, Hal., Trans. Linn. Soc. 1836, xvii. p. 318, 



female. C. nitidipeniiis, Brulle, Nat. Hist. Ins. Hym. iv. 



1846, p. 188, female. Ichneumon macrocercus, Spin., Gay's 



Hist. tis. Chile Zool. vi. 1851, p. 484, male and female. 



The above three authors record their species, which have not 



before been synonymised, respectively from the Straits of 



Magellan, Chili, and " Se halla en las provincias centrales, 



Santiago, &c." Dalla Torre misspells Spinola's specific name; 



and incorrectly associates Cryptus bellosus, Curt. (Ariti'anis signa- 



torius, Fab.), noted at Proc. Ent. Soc. iv. 1845, p. Ivii, with 



Haliday's species. This insect is very different from all the 



others of the present genus in its narrowly clear white internal 



orbits, and is probably worthy of generic rank in its slender and 



elongate antennae, short metathorax, small areolet, postfurcal 



upper basal nervure, and tremendously elongate terebra ; it is 



precluded from the genus Cryptus by the elongate cheeks and 



mandibles. The size varies considerably through the whole
