Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1906 edition. Excerpt: ...tarsal joint long, but less so than the first, lamellate denticles of fifth in two long and dense rows, of which one reaches to the articular cavity, the chelar claw with four or five lameliate denticles and a distinct antcapical tooth. Abdomen smooth. without sculpture, but not very shining. Length with abdomen extended 4.5 mm. HAB. Nogales, Arizona; bred from the same Delphacid. an adult, (Stobaera sp.) as the preceding; number 2463. I have retained this name for the present in my table of genera, though it may be synonymous with Dryinus, of which I have not a satisfactory description, nor any authentic European examples for comparison. It is certain that D-ryi'1iu.r 0rmc11ia'i's Asl,1mcomes very near to my Neodryimrs, but in that species, if the thorax be viewed from in front. the position of the parapsides is distinguishable, though the furrows are almost effaced. In Neodryinus proper there is no trace of these furrows. The very remarkable habit of the larva of Ncodryinus in covering its cocoon with the ruptured larval sac, which it removes from the leafhopper, is not found in any other genus of Dryinidae, nor does it occur in the case of D. ormenidis. To the Australian species of Ncodryimis, I now add two new species from Arizona. One of these was bred, and its cocoon greatly resembles those of the Australian species, as also does the mature insect. Dryinus alticola and D. iiiaciilicoriiis of Cameron, from Central America, are, I suspect, closely allied to these Arizona species. Black, the hind and middle tarsi, the fourth. fifth and more or less of the apical part of third joint of the antennae. clear teslaceous or ferruginous: scape of antennae dark fuscous, yellowish beneath. Front femora inwardlv with a rufescent line on the...show more
