These charts represent the counts in about 262 specimens of 

 T. 0. ordinoides, 387 of T. o. atratus, 37 T. o. elegans from the 

 Sierra Nevada and 41 from the San Bernardino mountains, 

 108 T. 0. vagrans, 235 T. o. bisciifatiis, 75 T. o. Jiauunondii, 

 and 40 T. o. couchii. The numbers vary slightly for the differ- 

 ent charts. The chart of gastrostege counts, however, is based 

 upon smaller numbers, since it includes only male specimens.
