A NEW MEMBER OF THE FAMILY THAUMASTOCORID^. 



By H. G. Barber, Roselle Park, N. J. 



Kirkaldy, 1907,^ established the new subfamily Thaumasto- 

 corinse of the family Lygseidae " on a single carded specimen " of 

 Thausmastocoris australicus, new genus and species, from 

 Queensland, Australia. His subfamily characterization based 

 upon the " structure of the head, labium, legs, etc.," was very 

 meager. Dr. Bergroth, 1909,- in describing from Tasmania a 

 new genus and species, Baclosygum depressmn, assembles the 

 chief characters from Kirkaldy's generic description of TJiau- 

 mcistocoris combining these with the characters of his Ba^lozygum 

 to formulate a more definite demarcation of the subfamily Thau- 

 mastocorinse. It is important to note in the words of this author 

 that his diagnosis of the subfamily " so far as the abdomen is 

 concerned is founded on the genus Baclozygum since Kirkaldy 

 was unable to examine the single gummed example of Thaumas- 

 tocoris and he tells me the specimen was lost in the drawing." 



Dr. Bergroth's characterization of this subfamily in Latin may 

 be translated as follows : 



" Jugse much longer than the non-sulcate tylus. Rostrum 

 not reaching posterior margin of the prosternum. Clavus 

 towards apex distinctly ampliated, commissure at least equally 

 as long as the scutellum. Membrane without veins. Anterior 

 legs inserted in the middle of the disk of the prosternum, ace- 

 tabulae closed up. Apex of the tibia between the two seg- 

 mented tarsi furnished with a membranous lobuliform cadu- 

 cous appendage somewhat distant from the tarsi. Venter of 

 male furnished with eight visible segments (besides the geni- 

 tal), the last two segments and the genital one asymmetrical, 

 apex of this on the left side (right seen from below) sinuate, 

 the latter [genital] obliquely suboval, genital aperture situated 

 on the right side. Venter of the female furnished with seven 

 visible segments, seventh segment large covering genital seg- 

 ment below. (Otherwise as in subfamily Geocorinse. Spiracles 

 not investigated.)"
