Abstract
The present paper deals with the chromosomes of seven forms of the Myrmeleonoidea covering six species of the Myrmeleonidae and one species of the Ascalaphidae. The results are summarized in Table 1.
It was suggested that the basic number of 14 in the Myrmeleoninae and that of 16 in the Dendroleoninae. Interesting is the fact that the Palparinae which is regarded as the most primitive one in the Neuroptera possesses the largest chromosome number so far observed in this order.
The V-shaped centriole was observed in Hagenomyia micaus.
