This form is very close in general appearance and structure to G. 

 marmoreus Pocock, so far as may be judged from the description. 

 It is separated because of a number of apparent differences, most 

 obvious of which is the much greater size and different form of the 

 penes. In Pocock's figure these are represented as shorter than the 

 legs and as curving apart; in the present form the penes are nearly 

 twice as long as the legs and much stouter. The inferior process of 

 the penult tergite is proportionately shorter and is more slender and 

 acute, while that of the preceding tergite is much narrower and more 

 acute. Striation of tergites as in G. marmoreus. Color from some- 

 what dusky chestnut to nearly black, with symmetrical series of yellow 

 marks along the dorsum and sides, these often becoming more obscure 

 caudad, and in one specimen are obsolete throughout. The antennae 

 are also blackish with a pale annulus about the proximal end of each 

 article. Labrum and a stripe across vertex of head yellow as in 

 G. marmoreus. 



Length, 5-6 mm.
