272 EXPERIMENT STATION RECORD. 



.The species noted as affecting orchard and shade trees are Macropsis 

 apicatis, Bythoscopus distinctus, Pediopsis tristis, P. trimaculata, P. 

 viridis, P.ferruginoides, Idiocerus altematus, I. branneus, I. monoliferce, 

 I. verticis, I. snowi, I. maculipennis, I. provancheri, and /. cratazgi. The 

 first (M. apicatis), the author states — 



"May be so plentiful as to give a rough appearance to the bark in places, and, 

 while not apparently producing distortion of the twigs, probably because they are 

 placed so close to the surface as not to affect the growing tissue, the fact that many 

 of the twigs affected are deadened at the tip would indicate possible injury in this 

 manner. The eggs occur mainly on the under surface of the twig, but whether this 

 position is to give the egg more uniform conditions by protecting it from direct sun- 

 light or to the avoidance of strong light by the adult, or some other reason, is a 

 matter of conjecture. The deposition of the summer eggs has not been observed, 

 but it doubtless coincides with that for the winter brood. 



"The larva' are stout and short, similar in color and shape to the adult, but entirely 

 covered with coarse bristle-like hairs, rendering it easily recognizable. Larva; and 

 adults were found in abundance on the new growth at the end of the twigs of honey 

 locust toward the end of June, occurring in hundreds on a single tree, and although 

 isolated trees, trees in hedgerows, and those in the native timber were examined, as 

 well as others in different parts of the State, none were found entirely free from this 

 insect. The larvae had all issued by the last of the mouth." 



The secoud (B. distinctus) occurs on black walnut, butternut, and on 

 hickory and hackberry where they are adjacent to the first-rnentioued 

 tree. Full-grown larv* are found during the secoud week in June and 

 a second brood appears before the middle of August. 



The species of Pediopsis are only briefly noted, but they all agree in 

 being tree feeders, both as larva? and as adults. P. tristis appears to 

 be confined to plum trees and is often accompanied by P. trimaculata, 

 which often exceeds the former in numbers. The most common species 

 is P. viridis affecting most all the willows. The remaining species, P. 

 ferruginoides, attacks the narrow-leaved willows. 



Monograph of the Phymatidas, A. Handlirsch (Ann. K. E. Naturh. Hofmus., 

 TVien, 12 (1807), pp. 127-230, pis. 6, figs. 35).— -The work is divided into 3 parts. The 

 first part deals with the questions of literature, morphology, anatomy, embryonic 

 development, life history, geographical distribution, as well as the systemic posi- 

 tion and relationships of the family. The Phymatidas, especially considered as 

 approaching the Aradida; and Tingitidse, the author, for morphological reasons, 

 places in the neighborhood of the Reduviida^. Their closest relatives are thought 

 to be the Stenopodinian genera, Phimophorus and Aulacogenia. 



The family is distributed over the palearctic, oriental, and neotropical regions. 

 Some three-fourths of the known species belong to the New World. None are found 

 to occur in Australia, Africa, or Madagascar. The 2 species of Phyneata described 

 by J. Scott as from New Zealand are thought very uncertain. 



The second part of the work is entirely systematic. Nine genera and 73 species 

 are recognized, and of these 3 genera and 29 species are new. Three natural groups 

 are recognized: Phymatinse with 1, Macroeephalime, with 6, and Carcinocorime 

 with 2 genera. The 3 new genera, Cnizocoris, Glossopelta, and Agrenocoris, belong 

 to the second group. 



Report of the professor of biology and geology, J. H. Panton (Ontario Ayr. 

 Col. and Expt. Farm Rpt. 1807, pp. 11-24, figs. 15). — This notes briefly some 13 injuri- 

 ous insects and new fungi, with brief popular statements in each case as to proper
