4 Inlieritaiice and Evolution in Orthoptera IT 



t^AB%, A%B@, BB^, B&B&) so closely resemble each other that they 

 were grouped together, and their jjrogenies not bred out. 



On Plate II it is attempted at this time to illustrate only twelve of 

 the fourteen true forms (multiple allelomorphs) used in this paper and 

 thirty-six of the hybrids, and those forms and hybrids carrying ©. The 

 distinctness of patterns is nowhere overdone and in some instances 

 underdone. Some of the forms illustrated in my former paper appear 

 again, a few of them, e.g., EE, II, and some of the hybrids, much better 

 represented. The form QQ resembles CO greatly except for the red 

 legs which are conspicuous, but it behaves as a true form. The form LL 

 (not illustrated) has three light brown stripes running longitudinally 

 along the pronotum, with the rest of the pattern somewhat mottled as 

 in most of the others. The form N'N (not illustrated) has a rufous 

 brown, somewhat bronzed, pi'onotum as the striking feature of its 

 pattern. Along with LI and N]^, many hybrids, and forms and hybrids 

 containing 0, used in the matings are not illustrated. 



The results are given in the form of tables. The arrangement is 

 such that the ancestry of the individuals of any mating niay be traced 

 back, and the progeny traced forward, as far as there are any records. 

 In the matings the gametic composition of the jjarents and the somatic 

 compo.sition of the offspring are given, and, unle.ss marked (R), the male 

 is on the left and the female on the right. The first line of figures 

 (totals) gives the actual numbers and the second line the Mendelian 

 expectation. The letters indicating the ])rog<!ny are placed alpha- 

 betically, from left to right. 



At this time the arrangements of the tables will suffice for the 

 presentation of tJie data. Matings 1-159 show exclusively the behaviour 

 of multiple allelomorphs, a continuation of the fii-st instalment. Matings 

 1G0-46S exhibit the behavinur of the chai-acter (") (or tlie factor for it). 

 This part also indicates further the behaviour of thi' multiple alldo- 

 niorplis; for there is no possibility of observing such a character, or 

 factor, as except along with chai'acters like A, B, 6', B, etc., and 

 their hybrids, from which it is, by its natui-e, inseparable. (Two other 

 characters ajDparently of the nature of 0, one of them appearing as 

 white specks on the femora and anterior promitum and inconspicuous, 

 the other a bright redness all over, head, body and legs, as well as 

 pronotum, almost as conspicuous as 0, have been discovered, but the 

 fjrms bearing them are only now being bred.) The cultures of both 

 groups have been carried on simultaneously, and, as the cross references 

 indicate, individuals fi-om one grouj) were frequently used for matings 

 in the others.
