2. Palpa7-es latipennis, Rbr. 



I have never seen the type of Rambur, which McLachlan considers 

 to be a good species. After Rambur's description, I have considered to 

 belong to P. latipemiis, two males from Angola and a female from the 

 Senegal ; one of the males is not now before me. After comparison with 

 the types of Walker, I considered M. cephalotes Walk, (not Rambur) to 

 be identical with his Af. fwfuracens (not Rambur's species, vvhich Mc- 

 Lachlan, after comparing the type, found new to him), and both were 

 identical with my species. Prof Peters brought home a male from Loanda 

 a httle smaller than the two males from Angola, but perfectly identical ; 

 it is now in the Berlin Museum. From those four specimens my detailed 

 description is made in Peters' Reise nach Mossambique, vol. v., p. 99. 

 My manuscript was delivered in 1853, printed in 1854, but published only 

 in 1862. As I have not received any separata, and as the book is rather 

 expensive, my work is very little known. I shall even now consider my 

 species as P. latipe/mis Rbr., until the contrary is shown by evidence 



Length of body, male, 66 m.m.; female, 55 m.ni. (not perfect). Exp. 

 alar., male, 1 18-136 m.m.; female, 144 mm. The appendages of the 

 male, now broken, were 3 m.m. long, and similar to those of P. iticlemens. 



The species, though visibly smaller, is so similar to P. i?iciemejis that 

 it was very nearly believed that P. latlpennis is a western variety, or at 

 least a representative variation of P. inclemens from the east coast. The 

 fact will have to be decided by a much larger material than the specimens 

 at my disposition. The differences are (I can not now compare the 

 appendages) the dilatation of the black middle band on the vertex, and 

 the want of a transversal black band below the antennse ; the color of legs 

 is more yellow, but in one specimen nearly brown ; the front wings are 

 narrower, less obtuse on tip, the large spots smaller, the apical one rudi- 

 mentary ; the hind wings are narrower, less obtuse on tip, the three basal 

 bands smaller, connected with each other, the first basal band nearly rudi- 

 mentary, forming only an indication of a narrow horseshoe-like incision ; 

 on the hind margin a number of rounded brown spots. 



Knowing the variability of large Myrmeleon, of course my opinion of 

 the difference of P. inclemens and latipcnnis has to be supported by a 

 larger material ; if I am right, and if P. latipennis Rbr. is surely different, 

 a new name should be given for my species.
